LS1043ARDB NAND not booting if program with cwflash.py

LS1043ARDB NAND not booting if program with cwflash.py

If boot from NOR and program NAND from uboot, it can boot from NAND without problem. Same NAND uboot image file (firmware_ls1043ardb_uboot_nandboot.img) is used for both scenario. 

If program NOR with cwflash.py, it can boot from NOR.

Commands used are:

fl_erase 0x0 0x3214e40
fl_write 0x0 firmware_ls1043ardb_uboot_nandboot.img

My LS1043ARDB is SCH-39019 REV F. According to schematic, the NAND is MT29F4G08ABBDA.  The dmesg also shows it's MT29F4G08ABBDA.
However, in Freescale\CW4NET_v2020.06\CW_ARMv8\Config\boards\LS1043A_RDB_init.py, it has an option

BOARD_REV_PD = True

with comment "LS1043A RDB-PD uses a new NAND flash device"

If BOARD_REV_PD = True, it use MT29F4G08ABBFAv1 instead of MT29F4G08ABBDAv1.
If BOARD_REV_PD = False, it use MT29F4G08ABBDAv1.

If BOARD_REV_PD = True is used, NAND program success (but verify failed) but unable to boot.
If BOARD_REV_PD = False is used, NAND program failed with error [FP: found bad block]

[CheeSiong]

When NAND is not bootable, there is no way of getting NAND boot successfully using cwflash.py

The only way to get NAND boot working is to program NAND from uboot.

When NAND is bootable, trying to program NAND using cwflash.py get the following results:
If BOARD_REV_PD = False is used, NAND program successfully and able to boot to uboot.
If BOARD_REV_PD = True is used, NAND program successfully but unable to boot. When this happened, the only way is to program NAND from uboot.

My LS1043ARDB is SCH-39019 REV F, may be BOARD_REV_PD = False should be used for my board.
But BOARD_REV_PD = False still failed NAND programming when NAND is not bootable.

Please configure the switch setting to configure the LS1043ARDB boot from NAND.

In CodeWarrior initialization file, do the following modification.

USE_SAFE_RCW = False

Modify to

USE_SAFE_RCW = True

Hi YiPing,

By setting USE_SAFE_RCW = True, I can start the CodeWarrior Flash with cwflash.py.
But it still can not boot up if not using CodeWarrior or CodeWarrior flash.
What I means is the board can't boot from NAND to uboot

Hi YiPing, Thanks for reply.

I'm new to this.
I still not able to find the way to take the dump using CCS.
Can you please share how to do IFC controller register dump for the 2 cases?
Or any doc/link can I reference?

For 
1. Boot from NOR and then Program NAND from u-boot prompt. Then boot form NAND
I use md command to read the memory by IFC address, is this correct?

Please share IFC controller register dump in two cases:

1. Boot from NOR and then Program NAND from u-boot prompt. Then boot form NAND
2. Programming NAND from CW try to boot. (Please take dump using CCS as U-boot is not available)

I have reported this defect to the  CodeWarrior development team.

They will resolve this issue in the next released version CodeWarrior.
