ls1043ardb use sdk2.0 can't recognized nor flash in kernel

[misakamikoto]

Hi  I use sdk0.4 0.5 before and everything is ok，but now I have to change sdk to v2.0，when I have ported uboot and kernel code，I found the nor flash can't be recognized in kernel showing the message below

[    1.163198] of-flash 60000000.nor: do_map_probe() failed for type cfi_probe

[    1.170224] of-flash 60000000.nor: do_map_probe() failed

and I found it fail at cfi_qry_mode_on in cfi_probe.c  I'm so confused with this.Did someone meet this before?

Can you show some opinions？

Hello misaka mikoto,

Please rebuild Linux kernel with the following options enabled.

CONFIG_FTL=y

CONFIG_MTD_CFI_BE_BYTE_SWAP=y

I attached my Kernel configuration file for you, you could use the following commands to rebuild Kernel itb image in SDK 2.0.

$bitbake virtual/kernel -c cleansstate

$bitbake virtual/kernel -c configure

Go the folder build_ls1043ardb/tmp/work/ls1043ardb-fsl-linux/linux-qoriq/4.1-r0/build to use the attached configuration file to replace .config.

$bitbake virtual/kernel

$bitbake fsl-image-kernelitb

Have a great day,

Yiping

Hi  I have solved this issue by myself as you mentioned due to wrong endian setting.I have debug this issue from cfi probe and check the id and QRY commands，finally I realize what it occured. Can you share how you debug this?
