LS1043aqds qspi u-boot - custom board

[carlos-m-ribeiro]

Hello,

We are using the ls1043aqds qspi u-boot in our custom board but after booting, we can not read in

0x7fb00000 address (our cpld id register):

=> md.b 0x7fb00000

x28: 0000000000000000 x29: 00000000fbc387d0

Should we activate something in defconfig to can read from these addresses?

Best regards

Please provide output of "md.l 1530000 40" and check that IFC chip-select is configured for the address 0x7fb00000.

If not - check U-Boot source "include/configs/ls1043aqds.h" and debug "drivers/misc/fsl_ifc.c".

Thank you and how we can check if IFC chip-select is configured for the address 0x7fb00000?

Best regards

And the output of "md.l 1530000 40"is:

01530000: 00000401

=> md.l 1530000 40
