Hey,

I want to inject CERR/MERR error in MTU from c code. So what is the procedure that I should follow. 

Lets say I want to inject CPU0 DLMU_STNDBY CERR/MERR, so which functions to use?

 

[PS: For injecting UCERR i just set MTU_MEMTEST0.B.DLMU_STNDBY = 1U. Just wanted to check if it is the right way?]

 

Thank you in advance

Hi there,

did you already check out the code-example on our GitHub?

Hi @MarkusNoll 

I checked the code and was able to inject CERR

Now my question is, after injecting alarm, I cleared it using  ECCD.B.CERR =0, the MTU CERR bit is cleared, but the MTU error is still showing "enabled" because of which corresponding SMU alarm is showing fault.

 

Can you help me with this

Thanks

Hello,

Do you run the same project or have you done any modification? Which register are you referring by 'MTU error is still showing "enabled"'? 

Thanks.

Hello,

If you are referring to the MTU status register, you can check the clear_MTU_MBIST_Errors function in the example. If you are referring to the SMU status register, it needs to be implemented as this example focuses on MTU. You can look at the SMU example in the following link for reference.

Thanks.
