ls1028ardb - How to change Code Warrior settings when changing emmc chip

pjw — Tue, 15 Dec 2020 06:40:09 GMT

Hi, I'm using ls1028ardb.
We are making custom boards, and we are trying to use emmc chips as chips other than those in bsp.

The question here is,
When I download image to the board using Code Warrior, is there anything need to set up? When connect the board to the host PC, it automatically recognizes the board, and I wonder if it recognizes the same thing even if I change the eMmc chip to another manufacturer's chip.

Thank you.

You could refer to section "CodeWarrior Connects to the Bare Board to do Flash Programing" in https://community.nxp.com/t5/CodeWarrior-for-QorIQ-Knowledge/Use-CodeWarrior-for-ARMv8-to-Debug-U-boot-and-Linux-Kernel-and/ta-p/1114872?attachment-id=18546 to do flash programing with CodeWarrior.

To program the empty custom board without valid RCW on the target board, you could modify "USE_SAFE_RCW = True" in CodeWarrior initialization file to use hard-coded RCW to connect to the target board, then do flash programming.

In CodeWarrior, all eMMC device uses algorithm SD_MMC.bin, so it is possible to use same eMMC flash algorithm even you change the eMmc chip to another manufacturer's chip.
