-
-0) Files of the M28/M28EVK port
--------------------------------
+Files of the M28/M28EVK port
+----------------------------
arch/arm/cpu/arm926ejs/mx28/ - The CPU support code for the Freescale i.MX28
arch/arm/include/asm/arch-mx28/ - Header files for the Freescale i.MX28
board/denx/m28evk/ - M28EVK board specific files
include/configs/m28evk.h - M28EVK configuration file
-1) Prerequisites
-----------------
-
-To make the M28 module or the M28 module or M28EVK board bootable, some tools
-are necessary. The first one is the "elftosb" tool distributed by Freescale
-Semiconductor. The other tool is the "mxsboot" tool found in U-Boot source tree.
-
-Firstly, obtain the elftosb archive from the following location:
-
- http://foss.doredevelopment.dk/mirrors/imx/elftosb-10.12.01.tar.gz
-
-We use a $VER variable here to denote the current version. At the time of
-writing of this document, that is "10.12.01". To obtain the file from command
-line, use:
-
- $ VER="10.12.01"
- $ wget http://foss.doredevelopment.dk/mirrors/imx/elftosb-${VER}.tar.gz
-
-Extract the file:
-
- $ tar xzf elftosb-${VER}.tar.gz
-
-Compile the file. We need to manually tell the linker to use also libm:
-
- $ cd elftosb-${VER}/
- $ make LIBS="-lstdc++ -lm" elftosb
-
-Optionally, remove debugging symbols from elftosb:
-
- $ strip bld/linux/elftosb
-
-Finally, install the "elftosb" binary. The "install" target is missing, so just
-copy the binary by hand:
-
- $ sudo cp bld/linux/elftosb /usr/local/bin/
-
-Make sure the "elftosb" binary can be found in your $PATH, in this case this
-means "/usr/local/bin/" has to be in your $PATH.
-
-2) Compiling U-Boot for M28
----------------------------
-
-Compiling the U-Boot for M28 is straightforward and done as compiling U-Boot
-for any other ARM device. For cross-compiler setup, please refer to ELDK5.0
-documentation. First, clean up the source code:
-
- $ make mrproper
-
-Next, configure U-Boot for M28EVK:
-
- $ make m28evk_config
-
-Lastly, compile U-Boot and prepare a "BootStream". The "BootStream" is a special
-type of file, which the i.MX28 CPU can boot. This is handled by the following
-command:
-
- $ make u-boot.sb
-
-HINT: To speed-up the build process, you can add -j<N>, where N is number of
- compiler instances that'll run in parallel.
-
-The code produces "u-boot.sb" file. This file needs to be augmented with a
-proper header to allow successful boot from SD or NAND. Adding the header is
-discussed in the following chapters.
-
-3) Installation of U-Boot for M28EVK to SD card
------------------------------------------------
-
-To boot an M28 from SD, set the boot mode DIP switches according to i.MX28
-manual chapter 12.2.1 (Table 12-2), PORT=SSP0, SD/MMC master on SSP0, 3.3V.
-
-An SD card the i.MX28 CPU can use to boot U-Boot must contain a DOS partition
-table, which in turn carries a partition of special type and which contains a
-special header. The rest of partitions in the DOS partition table can be used
-by the user.
-
-To prepare such partition, use your favourite partitioning tool. The partition
-must have the following parameters:
-
- * Start sector .......... sector 2048
- * Partition size ........ at least 1024 kb
- * Partition type ........ 0x53 (sometimes "OnTrack DM6 Aux3")
-
-For example in Linux fdisk, the sequence for a clear card follows. Be sure to
-run fdisk with the option "-u=sectors" to set units to sectors:
-
- * o ..................... create a clear partition table
- * n ..................... create new partition
- * p ............. primary partition
- * 1 ............. first partition
- * 2048 .......... first sector is 2048
- * +1M ........... make the partition 1Mb big
- * t 1 ................... change first partition ID
- * 53 ............ change the ID to 0x53 (OnTrack DM6 Aux3)
- * <create other partitions>
- * w ..................... write partition table to disk
-
-The partition layout is ready, next the special partition must be filled with
-proper contents. The contents is generated by running the following command (see
-chapter 2)):
-
- $ ./tools/mxsboot sd u-boot.sb u-boot.sd
-
-The resulting file, "u-boot.sd", shall then be written to the partition. In this
-case, we assume the first partition of the SD card is /dev/mmcblk0p1:
-
- $ dd if=u-boot.sd of=/dev/mmcblk0p1
-
-Last step is to insert the card into M28EVK and boot.
-
-NOTE: If the user needs to adjust the start sector, the "mxsboot" tool contains
- a "-p" switch for that purpose. The "-p" switch takes the sector number as
- an argument.
-
-4) Installation of U-Boot for M28 to NAND flash
------------------------------------------------
-
-To boot an M28 from NAND, set the boot mode DIP switches according to i.MX28
-manual chapter 12.2.1 (Table 12-2), PORT=GPMI, NAND 1.8 V.
-
-There are two possibilities when preparing an image writable to NAND flash.
-
- I) The NAND wasn't written at all yet or the BCB is broken
- ----------------------------------------------------------
- In this case, both BCB (FCB and DBBT) and firmware needs to be
- written to NAND. To generate NAND image containing all these,
- there is a tool called "mxsboot" in the "tools/" directory. The tool
- is invoked on "u-boot.sb" file from chapter 2):
-
- $ ./tools/mxsboot nand u-boot.sb u-boot.nand
-
- NOTE: The above invokation works for NAND flash with geometry of
- 2048b per page, 64b OOB data, 128kb erase size. If your chip
- has a different geometry, please use:
-
- -w <size> change page size (default 2048 b)
- -o <size> change oob size (default 64 b)
- -e <size> change erase size (default 131072 b)
-
- The geometry information can be obtained from running U-Boot
- on M28 by issuing the "nand info" command.
-
- The resulting file, "u-boot.nand" can be written directly to NAND
- from the U-Boot prompt. To simplify the process, the U-Boot default
- environment contains script "update_nand_full" to update the system.
-
- This script expects a working TFTP server containing the file
- "u-boot.nand" in it's root directory. This can be changed by
- adjusting the "update_nand_full_filename" varible.
-
- To update the system, run the following in U-Boot prompt:
-
- => run update_nand_full
-
- In case you would only need to update the bootloader in future,
- see II) below.
-
- II) The NAND was already written with a good BCB
- ------------------------------------------------
- This part applies after the part I) above was done at least once.
-
- If part I) above was done correctly already, there is no need to
- write the FCB and DBBT parts of NAND again. It's possible to upgrade
- only the bootloader image.
-
- To simplify the process of firmware update, the U-Boot default
- environment contains script "update_nand_firmware" to update only
- the firmware, without rewriting FCB and DBBT.
-
- This script expects a working TFTP server containing the file
- "u-boot.sb" in it's root directory. This can be changed by
- adjusting the "update_nand_firmware_filename" varible.
-
- To update the system, run the following in U-Boot prompt:
-
- => run update_nand_firmware
-
- III) Special settings for the update scripts
- --------------------------------------------
- There is a slight possibility of the user wanting to adjust the
- STRIDE and COUNT options of the NAND boot. For description of these,
- see i.MX28 manual section 12.12.1.2 and 12.12.1.3.
-
- The update scripts take this possibility into account. In case the
- user changes STRIDE by blowing fuses, the user also has to change
- "update_nand_stride" variable. In case the user changes COUNT by
- blowing fuses, the user also has to change "update_nand_count"
- variable for the update scripts to work correctly.
-
- In case the user needs to boot a firmware image bigger than 1Mb, the
- user has to adjust the "update_nand_firmware_maxsz" variable for the
- update scripts to work properly.
+Follow the instructions from doc/README.mx28_common to generate a bootable SD
+card or to boot from NAND flash.
