We have a custom board - largely based upon the NXP LS1043A-RGW Development board.
U-boot is working well enough that I have it booting with SD Card, then tftp'ing a
custom kernel.itb image that I built.
I am working with the LSDK 18.03 Flex-builder (I know its old, but its the only one that has
patches that allow building of the RGW version - which is significantly different than RDB)
Now, I have built a nand version of uboot, tftp the nand binary and write it into the nand flash
I confirm the RCW words are programmed, but I am not booting. I try to use CodeWarrior
and it doesn't seem to connect to the board (yes, I know how to setup a debug of SPL/U-boot,
I had to do that for the SD Card version).
Should I be able to debug NAND version from CodeWarrior Tap.
ps: I have a suspicion that there may be something wrong with SW-6, but I want to
make sure that I am trying to do something that is impossible before talking to
my hardware engineer who might not be very happy with this issue.
Please refer to section "8.1 U-Boot debug" in C:\Freescale\CW4NET_v2019.01\CW_ARMv8\ARMv8\Help\PDF\ARMv8_Targeting_Manual.pdf to debug u-boot.
Please refer to section "2. Debug u-boot with CodeWarrior for ARMv8" in https://community.nxp.com/docs/DOC-331981 to debug u-boot with the attach method.
