TJA1043TK Initialization in M4

vinothkumars — Sun, 20 Jun 2021 05:42:14 GMT

Hi,

I am working on TJA1043TK CAN initialization. Currently don't have GPIO expander and CAN_EN and CAN_STBY connected directly to the processor.

FCAN0_EN connected with GPT0_CAPTURE

FCAN_STB connected with GPT0_COMPARE.

I have to initialize the TJA1043TK . But, IRQ is not triggering to receive the message.

Please check my configuration and let me know what I am missing

pin_mux.h

pin_mux.c

if (SC_ERR_NONE != err)
{
assert(false);
}

Software wise this is proper only. There is hardware problem.
