Hi,
I would like to enable the FIELD_RETURN_LOCK bit in OCOTP_SW_STICKY register.
IMX6DQ6SDLSRM described it is set to always enable for protecting FIELD_RETURN fuse.
But, When I check OCOTP_SW_STICKY register, FIELD_RETURN_LOCK bit is always 0b.
I think that FIELD_RETURN_LOCK is disabling at my test environment.
How do I set to FIELD_RETURN_LOCK to 1b = enable?
From IMX6DQ6SDLSRM:
My test environment :
Board SABRE-AI CPU2
SoC i.MX6DL
BSP Linux 4.1.15_2.0.0_ga
My test result :
(1) OCOTP_SW_STICKY register read from U-boot prompt.
=> md.l 0x21bC050 1
021bc050: 00000018
(2) Add below line to DCD table in U-boot source code. I could not get any log from debug console after this modification.
DATA 4 0x021bc050 0x00000004

Hello,
I have the same issue I read 021bc050: 00000018 so seems that FIELD_RETURN_LOCK is not set.
I flashed a signed u-boot but no more log is seen on console, could you please share me the solution?
Thanks,
Mohamed Ali
