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, 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 is the following: + + * 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) + * + * 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 change page size (default 2048 b) + -o change oob size (default 64 b) + -e 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. -- cgit v0.10.2 From 22fe68fbdc6baf4d55782fd9803e6133c49b533d Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Tue, 8 Nov 2011 23:18:23 +0000 Subject: iMX28: Fix ARM vector handling This patch introduces proper ARM vector handling for i.MX28 CPU. This issue wasn't addressed because the interrupts weren't enabled on any ARMv5 core, therefore the issue wasn't noticed earlier. In previous implementation, the vectoring code used by i.MX28 CPU when an exception happened was that of the SPL. With this change, the branch target when an exception happens can be reconfigured by U-Boot.

This patch adds the minimal support for OMAP5. The platform and machine specific headers and sources updated for OMAP5430. OMAP5430 is Texas Instrument's SOC based on ARM Cortex-A15 SMP architecture. It's a dual core SOC with GIC used for interrupt handling and SCU for cache coherency. Also moved some part of code from the basic platform support that can be made common for OMAP4/5.

omap5: emif: Add emif/ddr configurations required for omap5 evm Add the emif configurations required for omap5 soc.Add the correct ddr part configurations required for omap5 evm board. EDB8164B3PH from ELPIDA is the part used on the board. Also changes are done to retain some part of the code common for OMAP4/5 and keep only the remaining in the Soc specific directories.

Configuration header(CH) is 512 byte header attached to an OMAP boot image that will help ROM code to initialize clocks, SDRAM etc and copy U-Boot directly into SDRAM. CH can help us in by-passing SPL and directly boot U-boot, hence it's an alternative for SPL. However, we intend to support both CH and SPL for OMAP4/5. Initialization done through CH is limited and is not equivalent to that done by SPL. So U-Boot has to distinguish between the two cases and handle them accordingly. This patch takes care of doing this.
