ls1046a - qspi boot - end kernel panic(VFS: Unable to mount root fs on unknown-block(0,0))

[2sanghaesea]

Hello,

I’m working with a custom board based on the LS1046A  CPU .

I’ve built a tiny Linux using LSDK 21.08.

During the initial boot, I encounter the following kernel panic:

Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block (1,0)

Interestingly, if I press the reset button, the system boots normally.

I’m not sure why this issue occurs.

Could you please advise me on how to resolve it?

ㅠㅠㅠㅠ

No problem with the bootargs.

Please download LSDK 21.08 pre-built image as the following.

$ wget https://www.nxp.com/lgfiles/sdk/lsdk2108/lsdk2108_yocto_tiny_LS_arm64.itb

Then on your target board, please try the following commands in u-boot.

=>tftp 0xa0000000 lsdk2108_yocto_tiny_LS_arm64.itb

=> bootm 0xa0000000#ls1046ardb

Thank you for your response.

As you mentioned, there are no issues booting via TFTP.
However, it seems there are problems when pulling the ITB file from the QSPI NOR flash.
This issue only occurs during the first boot.

Could this be a hardware problem, or could it be related to my kernel settings or U-Boot configuration?

Thank you.

[2sanghaesea]

Finally, I configured my system to run only U-Boot from the QSPI flash.

I modified the setup to boot by reading the kernel image from NAND flash.
