Hi ,

We are using LS2088A Based custom board. We are booting PBL and U-boot from QSPI Flash and we want to boot dpl, dpc, dtb, kernel and filesystem  from NAND flash. So can anyone suggest proper bootargs for this.

Thanks.

It looks like that your command "bootm" is incorrect

See the page 148 of LSDK 19.03 documentation.

 

=> bootm a0000000#<board-name>

The <board-name> can be: ls1012ardb, ls1012afrwy, ls1043ardb, ls1046ardb, ls1088ardb, ls2088ardb.


Have a great day,
Pavel Chubakov

Look at the Section 7.2.6.2 of LSDK 19.03 documentation:

https://www.nxp.com/docs/en/user-guide/LSDKUG_Rev19.03.pdf

 

Create .itb file.

Write this file to the NAND.

Use "nand read" command for reading .itb file to the SDRAM.

Use "bootm" command for booting.


Have a great day,

nand write 0xa0000000 0x0 $filesize
nand read 0xa0000000 0x0 $filesize
