Hello, I am trying to clear all alarm after successful startup for ECU, I managed to clear most alarms by clearing their sources first from MTU, however,Upon trying to clear both alarms in group7: 7[1] and 7[4], I could not find their sources to clear them before clearing the alarm, so any Ideas where can I find their sources? I am using TC37xExt

Hello TC37xx,
you can find the modules leading to these alarms in safety manual.
Please check, which any of the modules listed there with the list Fault identification interfaces containing your alarms does report the issue.

ALM7[1] is an LMU ECC uncorrectable error, and ALM7[4] is an EMEM ECC uncorrectable error. To avoid these try initialising their RAM contents. Look at LMU.MEMCON and EMEM.MEMCON to see if trying disabling ECC for instance stops the alarms from being raised until you have completed initialisation.

Also, you could write to SMU.AG7.SF1/SF4 to clear the status flags for these alarms.
