Failed to download bootloader by MFGTool

[oliverkuo]

Hi,

We have a custom board with i.MX6Q, we try to download bootloader by MFGTool but failed and the log shows "Failed to initialize memory!"

I would like to clarify which memory initial failed, Internal RAM or External RAM?

According to Chapter 8 of Reference Manual, seems to be Internal RAM?

Any comment how to debug such issue?

Appreciate for any suggestion!!

Hi Oliver

after loading mfg tools initramfs.cpio.gz.uboot (using algorithm Chapter 8)

processor runs small linux image, representing himself as msd for host computer.

Seems in this case "Failed to initialize memory!" is error while communicating with

board. More debug info can be obtained connecting terminal to board.

General procedure for new board: rebuild mfg tools firmware (initramfs.cpio.gz.uboot)

changing its code, using new ddr settings obtained from ddr tester, new iomux

settings and other changes compared with Sabre SD board configuration.

Best regards

igor
