Code Warrior Flashing and Bringin-Up Board with On-board eMMC [T1042]

[yusufalti333]

Hello nxp community

In my custom design [t1042 processor], I have a on-board eMMC connected to SDHC interface. So it means that I can not burn U-boot into mmc card using linux "dd" command.

Can code-warrior do a flash programming task to burn u-boot into on-board eMMC ?

1-) If answer is yes:

     a-) Is there any sample Code warrior .tcl file to memory map SDHC / eMMC interface into processor memory space. If yes:

          1-) Which sector/memory location should I use to burn u-boot and Fman Micro code to perform this flash programming task.

           2-) Are dip switch settings for booting with SD Card ( refer to SDK V2.0 - 1703 ) enough to boot after flash programming is succeeded ?

2-) If answer is no: Is there any suggested way to perform this ?

CodeWarrior for PowerPC Architecture doesn't support programming on-board eMMC.

On your target board, is there any other boot type supported, NOR, NAND or SPI flash?

We only have eMMC and NOR flash interfaces. Unfortunately, there is a POR sequence problem while reading data on NOR flash. I decided to check eMMC interface if supported to determine whether the problem is about nor flash or PLL lock step.
