CAN not working with the master #39

Closed taijisugiyama closed 7 months ago

Greetings, Thank you for your continuous help. Whenever I try to run CAN with foxgui, it seems to give me this error. I have checked the CAN connections and everything seems to be fine.

Dear @taijisugiyama,

Greetings, Thank you for your swift reply. I used the PCAN-View and I get the same error. Bus heavy error.

The GUI works and I can start it without a problem. Only when I start doing anything in it, then I get this error.

Also what is by default the baudrate used by master to communicate in CAN?

taijisugiyama commented 7 months ago

Initially when I flash the MCU. I receive no CAN messages in PCAN view

I have resolved the problem. After looking into the debugger and the code, I found out that I was getting an error flag for the SBC chips. I OTP the SBC chips again and now CAN seems to be working. But the PER SBC chip keeps shutting off and on (Because it seems to fail ABIST1). I have to run the SBC PER in debug mode to be able to use master.
