To keep the +kernel tree clean now, this document describes also some steps how +to add code for a new OMAP processor or OMAP based board to the OMAP Linux 2.6 +kernel tree. This is what the third section of this document is about. + +Section 4 of this README reports some rules to be followed to write +clean code to make it ready for easy inclusion into public OMAP Linux kernel. + +For more information also see TI's 'Linux Community for Texas Instruments OMAP +Processors' web page: + +http://linux.omap.com + +There, various downloads and resources can be found (e.g. documentation how +to build the kernel, how to use u-boot with OMAP Linux, pre-built tool chain +etc.). + +The mailing list for OMAP Linux is hosted there, too: + +http://linux.omap.com/mailman/listinfo + + +1. General hints how to start with OMAP Linux +-------------------------------------------------------------- + +The minimal setup is a arm-linux-gcc cross compiler, make, and some editor. +You will also most likely need a JTAG to flash the bootloader for the first +time. + +The first step is to get a bootloader for your board, u-boot is the +recommended one: + +http://www.denx.de/en/Software/GIT + +Then you need to compile it with the same cross compiler as you would use +for the Linux kernel. Then you need to flash it to the board either via the +serial port, or by using a JTAG. + +Once you have the bootloader running, you can compile the kernel. + +You can get the OMAP sources either from the OMAP GIT tree, or by +applying patches. The OMAP GIT tree has the most up to date sources +and is the recommended one. + +- Using GIT and cloning OMAP GIT tree please follow the README at: + +http://www.muru.com/linux/omap/README_OMAP_GIT + +Hint: If you are sitting behind a firewall and have to use a proxy for +internet access, you can access GIT by http by setting the +http_proxy envirionment variable: + +http_proxy=http://proxy_username:proxy_password@proxy_name:proxy_port/ + +If you use bash shell, then this might look like: + +export http_proxy=http://foo:123@abc.host.com:8080/ + +with: + +foo: Your user name for the proxy +123: Your password for the proxy +abc.host.com: The name of your proxy you use for internet access +8080: The port used on to access the proxy + + +- Using Patches: + +If you don't want to use GIT, then you can do the same thing with patch. + +Download the latest OMAP Linux patch from: + +http://www.muru.com/linux/omap/ + +Get a matching Linux kernel from: + +ftp://ftp.kernel.org/pub/linux/kernel/v2.6/ + +For example, if you download Linux-2.6.4-omap1 from muru.com, then you need +linux-2.6.4 kernel from kernel.org: + +$ wget ftp://ftp.kernel.org/pub/linux/kernel/v2.6/linux-2.6.4.tar.bz2 +$ tar xjf linux-2.6.4.tar.bz2 +$ cd linux-2.6.4 +$ cat ../Linux-2.6.4-omap1 | patch -p1 + +Note: If OMAP patch from muru.com is against a kernel release candidate, +marked by -rcX, then kernel can be found on kernel.org under v2.6/testing/ + +Now, if you have a local kernel tree, either by GIT or by patch, you +should look into arch/arm/configs/ to see which of the various omap_xxx +configurations there you want to use. For example, if you have a OMAP1510 +based Innovator board, you select omap_innovator_1510_defconfig by + +$ make omap_innovator_1510_defconfig + +at top level directory (linux-2.6.4 in the example above). + +Then you can compile the kernel with + +$ make vmlinux + +Or make Image or make zImage or make uImage. + +Once you have the kernel compiled, you can upload it to the board via serial +port or JTAG (see below). + +Then you need a root file system either as initrd or on the flash. + +Once you have the system booting to Linux, you can use pretty much any Linux +applications cross compiled for ARM. + + +2. JTAG usage +-------------------------------------------------------------- + +If the flash of your board is really 'empty' and no bootloader is on the board +(e.g. u-boot) then you need a JTAG connection. With JTAG you can write +a bootloader to board's flash or download OMAP Linux kernel. For OMAP +commercial JTAG tools are available, so you have to pay for it. + +Examples are TI's Code Composer Studio (CCS) or Lauterbach's TRACE32 JTAG. + +- Linux kernel download with CCS + +You can use CCS to directly load an ELF file to your board. For example, use +arch/arm/boot/compressed/vmlinux. zImage isn't suited because it is not an ELF +file. CCS looks for .out files, so copy arch/arm/boot/compressed/vmlinux +to vmlinux.out and load it using CCS. Or use the filter *.* to select +vmlinux directly. Remember to run arm-linux-strip on ELF file first as CCS +get stroppy about unstripped ELF files. + +If you want vmlinux to be linked to run at a specific address, you can use +the CONFIG_ZBOOT options in the kernel build. But first try without +CONFIG_ZBOOT as the compressed image should be able to run from address +zero (if your CCS .gel files map address zero.) + +Otherwise, use something like this: + +CONFIG_ZBOOT_ROM=y +CONFIG_ZBOOT_ROM_TEXT=10408000 +CONFIG_ZBOOT_ROM_BSS=10800000 + +Also note that CCS is pretty useless for debugging Linux as it doesn't +properly handle virtual memory. In other words, once the MMU is +turned on and Linux is using virtual memory, CCS can no longer +properly disassemble, set breakpoints or read memory. + + +- Linux kernel download with Lauterbach TRACE32 + +To be done. + + +3. How to add new processor or board to OMAP Linux kernel tree +-------------------------------------------------------------- + +It is assumed that the OMAP processor to be added is based on an already +supported ARM core (e.g. ARM925 or ARM926). How to add support for new ARM +processor core that is not supported by ARM Linux is not scope of this document. + +1. If a new OMAP processor should be added, identify the ARM core of this +processor. E.g. at time of writing this document in March 2004 OMAP730 (ARM926 +core), OMAP1510 (ARM925 core) and OMAP1610 (ARM926 core) are supported. + +For a new board or device, identify the OMAP processor on the board. E.g. at +time of writing this document in March 2004 four boards are supported: +Innovator1510 (OMAP1510 processor), Innovator1610 (OMAP1610 processor), +Perseus2 (OMAP730 processor) and H2 (OMAP1610 processor). + +Please refer http://www.muru.com/linux/omap/ to get latest information on the +list of boards supported. + +/* Discussion needed: How to handle the tons of compatible processors? +E.g. what to do if OMAP16xx is mainly identical with OMAP16yy? */ + +2. Start with arch/arm/mach-omap[1/2]/Kconfig and add a new processor or board +option. + +To add a new processor add a new config option to the "OMAP Core Type" choice. +See examples for the syntax. The config option has to be called "ARCH_OMAPxxxx" +where xxxx is the number of OMAP processor. Don't forget to select a existing +clock frequency or to add a new one in "OMAP Feature Selections" section for +your new processor. + +To add a new board or device, add a new config option to the "OMAP Board Type" +choice. See examples for the syntax. The config option for boards has to be +called "MACH_OMAP_yyyy" where yyyy is the board name. Don't forget to add a +short help. + +Note: Kernel 2.6 Kconfig system will automatically expand the configuration +names with a leading "CONFIG_". So "ARCH_OMAPxxxx" will be expanded to +"CONFIG_ARCH_OMAPxxxx" and "MACH_OMAP_yyy" will expand to +"CONFIG_MACH_OMAP_yyyy". In code this can then be used by macros like +"#ifdef CONFIG_ARCH_OMAPxxxx" and "#ifdef CONFIG_MACH_OMAP_yyyy". + +Note: How to handle boards which are compatible or extensions of other boards? +See MACH_OMAP_H2 for example. The H2 depends on MACH_OMAP_INNOVATOR and expands +it. This is done by an additional select MACH_OMAP_INNOVATOR in MACH_OMAP_H2 +configuration option. With this the whole MACH_OMAP_INNOVATOR configuration is +selected and an additional symbol CONFIG_MACH_OMAP_H2 is available to +distinguish between INNOVATOR and H2 where necessary. + +3a. Only for new processors: Add the ARCH_OMAPxxxx to the correct ARM core in +arch/arm/mm/Kconfig. E.g. ARCH_OMAP730 in CPU_ARM926T configuration. + +3b. Only for new boards: Register the board within ARM Linux machine +registration system from RMK. For the CONFIG_ section use the same name like +in arch/arm/mach-omap[1/2]/Kconfig. E.g. MACH_OMAP_yyyy. For MACH_TYPE_ section use +OMAP_yyyy where yyyy is the board name like above. + +Note: The elements of RMKs machine registration are used in +arch/arm/tools/mach-types. While kernel compilation +include/asm-arm/mach-types.h is generated automagically from this file. The +content of mach-types.h then is used for machine identification by kernel +bootcode and can be used for board identification. + +Note: The ARM Linux machine registration system from RMK can be found under: + +www.arm.linux.org.uk/developer/machines/ + +Note: Only OMAP based boards should be registered to RMKs registration +system. Not processors. + +4. Add a processor or board specific header file in include/asm-arm/arch-omap/. +Use board-yyyy.h with yyyy board name or omapxxxx.h with xxxx processor number. + +5. Add a processor or board specific section into include/asm-arm/arch-omap/ +hardware.h. Use examples for syntax and use CONFIG_ names as defined in +arch/arm/mach-omap[1/2]/Kconfig. + +6. Add processor or board specific macros to board-yyyy.h or omapxxxx.h. The +macros to these specific files have to be named OMAPxxxx_ with xxxx processor +number to make them unique. + +7a. Only for new boards: Add a file board-yyyy.c with yyyy board name to +arch/arm/mach-omap[1/2]/. Put board specific initialization code and resource +description into this file. The first element of MACHINE_START must be equal to +MACH_TYPE_ section of machine registration (see arch/arm/tools/mach-types after +machine registration at RMKs registration system). + +Put only code into this file that is board specific and not common. See other +board files for examples. + +7b. Only for new processors: Add processor specific IO description and +iotable_init() to arch/arm/mach-omap[1/2]/io.c. See examples for the syntax. + +If you have introduced new clock definition in 2., add support for this new +clock in include/asm-arm/arch-omap/clocks.h and arch/arm/mach-omap[1/2]/clocks.c. + +8. Only for new boards: Add "obj-$(CONFIG_MACH_OMAP_yyyy) += board-yyyy.o" with +yyyy board name to arch/arm/mach-omap[1/2]/Makefile. This is used to compile your new +board specific initialization code from 7a. + +9. Check if other of the existing files have to be adjusted for the new +processor or board. Things to check: + +- Pin multiplexing +- GPIO configuration +- Power Management +- Clocking +- Interrupt controller and interrupt configuration +- Additional board specific things (e.g. FPGAs) + +If other existing files or device drivers have to be changed, use the following +mechanism for processor specific things: + +#ifdef CONFIG_ARCH_OMAPxxxx + if (cpu_is_omapxxxx()) { + /* Do the OMAPxxxx processor specific magic */ + } +#endif + +Note: cpu_is_omapxxxx() macro is defined in include/asm-arm/arch-omap/hardware.h +and uses OMAP_ID_REG for runtime processor identifcation. + +For board differentiation use board macro from include/asm-arm/mach-types.h: + +#ifdef CONFIG_MACH_OMAP_yyyy + if (machine_is_omap_yyyy()) { + /* Do the board specific magic */ + } +#endif + +Note: If technically possible and already implemented the OMAP Linux kernel +has support for a "one binary fits all" machanism. That is, the goal is to be +able to enable support for multiple OMAP processors and/or boards in Kconfig +system. Then it is decided by bootparameters and at runtime on which processor +and/or board the kernel is actually running on. With this machanism it is +possible to use the same kernel binary on different OMAP processors or boards +without recompiling. This is achived by the cpu_is_omapxxxx() and +machine_is_omap_yyyy() macros. + +On the other hand, for memory limited embedded systems it should be possible +to compile the kernel with support for only one processor/board combination. +For this a kernel binary is necessary which isn't bloated with code for all +other (unused) processors and boards. This is achived by using the preprocessor +CONFIG_ARCH_OMAPxxxx and CONFIG_MACH_OMAP_yyyy macros around the runtime +cpu_is_omapxxxx() and machine_is_omap_yyyy() selection. + +At the moment, the price for this flexibility is a increased number of #ifdef's +throughout the code. + +10. Configure the kernel by make menuconfig or make xconfig and select the new +processor or board. + +11. Compile the kernel by an appropriate cross compilation toolchain. Make this +until the code compiles error and warning free. The kernel should also be +compiled with the various debug checking thingies enabled (e.g. +CONFIG_DEBUG_SPINLOCK, CONFIG_DEBUG_PAGEALLOC etc.). + +/* ToDo: Anything to say about toolchain? */ + +12. Download the kernel image to the board and test it until it works ;-) + +It's not in the scope of this document how to do this (use a appropriate +bootloader or JTAG download). + +Note: The kernel initialization code expects some special values in the +registers R0, R1 and R2 of the ARM processor. These registers have to be +written by bootloader or debugger before starting the kernel. R0 has to be +zero, R1 has to contain the machine number from machine registration in +arch/arm/tools/mach-types. R2 points to the physical address of tagged list +in system RAM. For more information see Documentation/arm/Booting. + +While testing a new processor or board configuration, it is recommended to +enable low level debugging. This uses low level output functions to print kernel +messages on serial line before console is working. Enable it by + +Kernel hacking -> Kernel debugging -> Kernel low-level debugging functions + +in kernel configuration system. + +13. Check that no other processors or boards are broken by the new code. A first +test is to successful compile the other omap_xxx configurations from +arch/arm/configs/. Do this by e.g. + +cd linux +make omap_innovator_1510_defconfig +Compile the kernel + +Even better: Enable support for several processors and boards in Kconfig +system and compile kernel successfully. + +14. Only for new boards: Add a new default board configuration to +arch/arm/configs. Use omap_yyyy_xxxx_defconfig with yyyy boardname and xxxx +processornumber as filename. + +15. If the new code works, compiles without warnings and seems to break no other +configurations, post a patch to linux-omap-open-source@list.ti.com. + +With sending a patch to the community, it is reviewed, can be used and tested by +other users. It then can be included into the public OMAP kernel tree. + +16. Then adapt device drivers or write additional drivers for non-existing +processor peripherals or board devices. Improve and maintain the code for your +new processor or board. + +------------------------------------------------------------------ +Last modified 15.

However, we cannot customise + * keyboard/mouse settings in this case. So we live with the defaults + * as setup by the Juno UR8HC007-001 whatever they may be. + * 2. Keyboard auto repeat does not work. See 1 above. : ) + * + * + * TODO: + * + * 1. Complete DPM/LDM stubs and test. + * 2. Add SPI error handling support, i.e. resend, etc.,. + * 3.
