We wish to flash a JFFS2 Linux root filesystem and kernel image into the 512MB NAND on the AM1808 EVM and then boot completely from NAND.
Steps are given below
- compiled uboot with nand support
- UBL and uboot for nand are flashed on NAND
- given boot arguments are:
setenv bootcmd 'nand read.e 0xc1180000 0x780000 0x4600000; nboot.e 0xc0700000 280000 0x220000; bootm 0xc0700000 '
setenv bootargs console=ttyS2,115200n8 rw ip=172.16.19.14 nfsroot=172.16.13.100:/home/filesys,nolock mem=32M
While booting, MTD partition for NAND is not created.
How to get MTD NAND partition?
Can someone please help me understand the recommended method for programming the NAND filesystem and kernel image?
The boot logs (nfs boot) are attched inline,
U-Boot > boot
nand - NAND sub-system
Usage:
nand info - show available NAND devices
nand device [dev] - show or set current device
nand read - addr off|partition size
nand write - addr off|partition size
read/write 'size' bytes starting at offset 'off'
to/from memory address 'addr', skipping bad blocks.
nand erase [clean] [off size] - erase 'size' bytes from
offset 'off' (entire device if not specified)
nand bad - show bad blocks
nand dump[.oob] off - dump page
nand scrub - really clean NAND erasing bad blocks (UNSAFE)
nand markbad off [...] - mark bad block(s) at offset (UNSAFE)
nand biterr off - make a bit error at offset (UNSAFE)
