Hi There I am trying to use new code( 2010.03 ) on my development board(mini2440) found out there is no command (dynenv and mtdparts) anymore. Are there any replacement for them? Thanks Craig

[U-Boot] [0/6] Patch serie UBI min I/O size fixes
by Holger Brunck 04 Apr '11

04 Apr '11

This patch serie fixes a problem in the UBI layer. The min I/O size has currently a fixed value of 1 for NOR flashes. But for NOR flashes the min I/O size has to be equal to the size of the writebuffer of the flash. Therefore the mtd layer was enhanced with the writebuffer which was later on used in the ubi layer to set the min I/O size. This patches fixes problems with flash types with a writebuffersize > 128 Byte and is mainly taken from the similar linux patches. See MTD mailing list posts: http://lists.infradead.org/pipermail/linux-mtd/2010-December/033460.html Without the u-boot patches attaching to a ubi device with a min I/O buffer larger than 128 would fail. Best Regards

[U-Boot] [STATUS] U-Boot v2011.03 released - Merge Window OPEN
by Wolfgang Denk 04 Apr '11

04 Apr '11

Hello all, U-Boot v2011.03 has been released and is available from the git repository and the FTP server. KNOWN ISSUES: - The cleanup after the reorganization of the ARM code has not been completed yet. At the moment, some 100+ RM boards are *broken* and *do not compile*. Board maintainers or other interested parties are requested to adapt their boards within the current merge window. All boards that have not been converted by the end of this merge window, i. e. that are still broken then, are considered unmaintained and without interest to the community and will be removed. - We still have not found a new network custodian yet. Are there any volunteers? The Merge Window for the next release (v2011.06) is open until Sun Apr 17, 2011, 23:59:59 CEST = 16 days remaining. The next release v2011.06 is scheduled for June 12, 2011.

[U-Boot] Booting kernel from NAND flash on AT91SAM9 custom board using fsload
by Nicholas Kinar 04 Apr '11

04 Apr '11

Hello, I've designed a custom circuit board based around the AT91SAM9RL64 processor from Atmel. This is an ARM9 AT91SAM9 series chip. The Atmel evaluation kit for this processor is supported by U-Boot, and the configuration header file can be found in the u-boot-2010.09 source code distribution (/include/configs/at91sam9rlek.h). To support my custom hardware, I've made small changes to the /include/configs/at91sam9rlek.h configuration file and to the files in the /board/atmel/at91sam9rlek/ directory. On my custom circuit board, the AT91bootstrap first-order bootloader is loaded from SPI Dataflash. In turn, the AT91bootstrap code loads U-Boot to SDRAM memory and then jumps to the load address. The U-Boot binary is also stored on SPI dataflash. I am able to successfully load U-Boot on my custom hardware, and I am able to use the nand subsystem commands to access the NAND flash. I would like to use the fsload command to load the Linux kernel from a JFFS2 filesystem written to the NAND flash, but to me it is not immediately clear what I need to modify in the U-Boot code to be able to do this. Perhaps the YAFFS filesystem would be more appropriate? I've found several mailing list threads on a related question, but I still can't determine how to boot from NAND flash. Does fsload only support NOR flash, or is it possible to use fsload on NAND flash? [1] http://lists.denx.de/pipermail/u-boot/2007-December/027578.html [2] http://www.mail-archive.com/u-boot@lists.denx.de/msg28173.html [3] http://old.nabble.com/NAND-boot-from-file-td7930776.html [4] http://blackfin.uclinux.org/gf/project/u-boot/forum/?_forum_action=ForumMes… As suggested in thread [4] above, I tried replacing jffs2_1pass.c with jffs2_nand_1pass.c in the fs/jffs2 directory. Also as instructed in the README.NAND, README.JFFS2 and README.JFFS2_NAND files found in the /doc/ directory, I've tried defining the following in my /include/configs/at91sam9rlek.h configuration file: #define CONFIG_JFFS2_NAND 1 #define CONFIG_CMD_JFFS2 #define CONFIG_SYS_MAX_FLASH_BANKS 1 #define CONFIG_CMD_NAND 1 However, after making these changes, the compilation process does not work, with the following error being reported: make[1]: Entering directory `/home/nkinar/DEVICE-CODE/uboot/u-boot-2010.09/common' arm-none-linux-gnueabi-gcc -g -Os -fno-common -ffixed-r8 -msoft-float -D__KERNEL__ -DTEXT_BASE=0x23f00000 -I/home/nkinar/DEVICE-CODE/uboot/u-boot-2010.09/include -fno-builtin -ffreestanding -nostdinc -isystem /home/nkinar/CodeSourcery/Sourcery_G++_Lite/bin/../lib/gcc/arm-none-linux-gnueabi/4.5.1/include -pipe -DCONFIG_ARM -D__ARM__ -marm -mabi=aapcs-linux -mno-thumb-interwork -march=armv5te -Wall -Wstrict-prototypes -fno-stack-protector \ -o cmd_jffs2.o cmd_jffs2.c -c cmd_jffs2.c: In function 'mtd_device_validate': cmd_jffs2.c:172:24: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'flash_info' cmd_jffs2.c:172:24: error: 'flash_info' undeclared (first use in this function) cmd_jffs2.c:172:24: note: each undeclared identifier is reported only once for each function it appears in cmd_jffs2.c:172:35: error: expected expression before ']' token cmd_jffs2.c: In function 'get_part_sector_size_nor': cmd_jffs2.c:275:22: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'flash_info' cmd_jffs2.c:275:22: error: 'flash_info' undeclared (first use in this function) cmd_jffs2.c:275:33: error: expected expression before ']' token cmd_jffs2.c:279:2: error: 'flash_info_t' undeclared (first use in this function) cmd_jffs2.c:279:16: error: 'flash' undeclared (first use in this function) make[1]: *** [cmd_jffs2.o] Error 1 make[1]: Leaving directory `/home/nkinar/DEVICE-CODE/uboot/u-boot-2010.09/common' make: *** [common/libcommon.a] Error 2 What do I need to update in U-Boot to be able to use fsload on my custom hardware?
