SRC_SBMR1 Boot Problem

Question asked by Itamar Levit on Jul 9, 2019

Maris is a big company that produces IMX6Q boards located in Israel.

We generally boot from NAND or SD or Serial Downloader.
With few imx6 boards, we have a problem that the SRC_SBMR1 is zero.
And as a result, it isn't booting
We try to fuse it instead of putting resisters
But is was the same results.
SRC Meomey Registers:
0x020D8000: [00000521 00000000 00000001 00000000]
0x020d8010: [00000000 00000000 0000001f 20000001]

We got This results by change the resisters to boot from fuse (but without do fusing)

We try to find what causes this problem because others board boot OK.

We need direction how to discover this HW problem.
