RM57L843: How to reset DCC Module after DCC error signaling

Jinwook KIM

Part Number: RM57L843

Hello.

I implemented DCC self test code. (DCC Mode is set to continuously mode. NOT Oneshot mode!)

I checked the occurrence of DCC Error Signal by applying Fault Injection to dccREG1->VALID0SEED. (dccREG1->VALID0SEED = 72u)

However, ESM DCC Error Sginal continues to occur without stopping after fault injection.

Question : How to stop ESM DCC Error and return to normal DCC behavior?

Below is my code.

dccInit() Code

Fault Injection

Error Signal Check

Hi Jinwook,

Are you clearing the ESM flag after error?

After ESM error occurred the flag will be in SET position for until we cleared the corresponding ESM flag.

And did you test in one shot mode? Do you see any difference?

Thanks & regards,
Jagadish.

Hi Jagadish.

Thank you for your reply.

I forgot to clear ESM flag. It's my mistake.

Best regards.
