Hi,
I use ti-sdk-am335x-evm-05.05.00.00 source code for AM335x evm board, and then I can load SPL, U-boot, uImage and ubi.img to nand flash. I can boot from nand flash, but it was fialed when mount UBIFS filesystem via nand, the log is as below:
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

When creating UBIFS filesystem, I use the following command to create ubi.img:
mkfs.ubifs -r filesystem/ -F -o ubifs.img -m 2048 -e 126976 -c 1580 -v
ubinize -o ubi.img -m 2048 -p 128KiB -s 512 -O 2048 -v ubinize.cfg
----------------------------------------------------------------------------------------------------------------------------------------------------------------
The ubinize.cfg is as below:
[ubifs]
mode=ubi
image=ubifs.img
vol_id=0
vol_size=192MiB
vol_type=dynamic
vol_name=rootfs
vol_flags=autoresize
--------------------------------------------------------------------------------------------------------------------------------------------------------------
When flashing UBIFS image to nand partition, the sequence is as below: (I switch SYSBOOT to SD card to boot, and flash ubi.img to nand)
mw.b 0x82000000 0xff 0x2f80000
mmc rescan
fatload mmc 0 0x82000000 ubi.img
nandecc hw 2
nand erase 0x780000 0xf880000
nand write 0x82000000 0x780000 0x2f80000
-------------------------------------------------------------------------------------------------------------------------------------------------------------------
I try to reflash nand. But the result is the same when mount filesystem via nand.
Could you tell me what is wrong? Thanks.
