One clarification:When I create a jffs2 filesystem on /dev/mtd2 using the process described in:
http://linux.omap.com/pipermail/davinci-linux-open-source/2008-January/004858.htmlThe kernel in /dev/mtd1 is no longer bootable. U-boot does not recognize the kernel as valid anymore.
Philip -------- Original Message -------- Subject: NAND Flash usage Date: Mon, 21 Apr 2008 14:32:44 -0400 From: Philip Balister <[EMAIL PROTECTED]>To: davinci-linux-open-source@linux.davincidsp.com <davinci-linux-open-source@linux.davincidsp.com>
I'm working with a Lyrtech SFF SDR board, I have Linux running on the board using root over NFS. I boot the kernel from NAND flash. I have created three partitions in the flash, but when I flash_eraseall I wipe the kernel out of NAND. After I flash_eraseall I can mount a jgffs2 filesystem and create a filesystem as shown in: http://linux.omap.com/pipermail/davinci-linux-open-source/2008-January/004858.html Does anyone have any ideas? I've modified the evm board files to suit this board. Philip Here is the partition table in the board file: struct mtd_partition davinci_evm_nandflash_partition[] = { { .name = "Bootloader", .offset = 0, .size = 5 * SZ_128K, .mask_flags = MTD_WRITEABLE, }, { .name = "Kernel", .offset = MTDPART_OFS_APPEND, .size = SZ_2M, .mask_flags = MTD_WRITEABLE, }, { .name = "File System", .offset = MTDPART_OFS_APPEND, .size = MTDPART_SIZ_FULL, .mask_flags = 0, } }; Here is cat /proc/mtd: [EMAIL PROTECTED]:~# cat /proc/mtd dev: size erasesize name mtd0: 000a0000 00020000 "Bootloader" mtd1: 00200000 00020000 "Kernel" mtd2: 07d60000 00020000 "File System" [EMAIL PROTECTED]:~# I set the mtd debug level higher, here are seemingly related messages: DaVinci NAND Controller rev. 2.1 Warning: NAND config: Set A1CR reg to 0x0432018c, was 0x0432229c, should be done by bootloader.
