Hi

am using Tc37x

Alm6[19-21] is meant for the modules below

I have cleared the corresponding MTU alarms, but the SMU alarm 6[20] is not getting cleared

Any suggestion

Thanks

ALM6[20] is the OR of following modules (I expect you have an TC39x):

DMA - Uncorrectable Critical error
MCDS - Uncorrectable Critical error
PSI5 - Uncorrectable Critical error
SCR.XRAM - Uncorrectable critical error
SCR.RAMINT - Uncorrectable Critical error
GIGETHERNET.RX0 - Uncorrectable Critical error
GIGETHERNET.TX0 - Uncorrectable Critical error
SDMMC - Uncorrectable Critical error

Alarm is not cleared because any of this modules has an uncorrectable critical error (e.g. SRAM not initialized).

Hi @MoD 

am using tc37x

I have cleared all UCERR and SERR and FaultSTS of all "ORed" modules

Still after clearing smu alarm it doesnt get set to low

Hi 

Can anyone please help me with this!

[MoD]

Check CCUCON5 that the GETHDIV bitfield is not 0. If GETHDIV is 0, then this can be result that ALM6[20] can't be cleared.

Hi @MoD 

Thanks for the info, I will check once

If suppose GETHDIV is 0, then what should be done?

should just update GETHDIV to some other allowed value than 0? [ie 1,2,3,4]

[yrun431]

Update: - I checked the GETHDIV value, it is set to 2 meaning fsource0/2. So that doesnt seem to be the problem

[MoD]

Any of the following RAMs has an ECC error therefore, you can't reset the alarm. Your software access any of this RAMs?

DMA - Uncorrectable Critical error
PSI5 - Uncorrectable Critical error
SCR.XRAM - Uncorrectable critical error
SCR.RAMINT - Uncorrectable Critical error
GIGETHERNET.RX0 - Uncorrectable Critical error
GIGETHERNET.TX0 - Uncorrectable Critical error

Initialize the RAMs via the MTU (memory test controller) to remove ECC errors.

I have enabled mtu clock. I am able to clear other ECC errors[CPUx, DAM0] and corresponding SMU alarms

Just 

DMA - Uncorrectable Critical error
PSI5 - Uncorrectable Critical error
SCR.XRAM - Uncorrectable critical error
SCR.RAMINT - Uncorrectable Critical error
GIGETHERNET.RX0 - Uncorrectable Critical error
GIGETHERNET.TX0 - Uncorrectable Critical error

These are creating a problem

If you see the image, all mtu alarms are disabled

Thanks

were u able to resolve the error? what was the problem
