AM2732: customized SBL

currinwang

Part Number: AM2732

I want to import CAN module to the SBL so I changed the example.syscfg file add MIBSPI and MCAN config(my CAN chip is TJA1145) as shown below:

But after I burn the SBL to onchip flash and restart from QSPI mode, the chip can not startup. SBL does not have any printing information.

I just modified the example.syscfg file and not modify the code of SBL.

I removed MIBSPI configuration then SBL can start normally.

But the CAN chip TJA1145 uses the SPI to config

Hi,

Can you verify that you are not using conflicting IOMUX pins for the CAN and MIBSPI signals?

I am assigning this to our AM273x SBL expert.

Thank you,

I confirm that there are no IO pin conflicts.

I was wondering if it was due to a conflict in the EDMA configuration between SPI and QSPI？

Thanks, I have identified the issue, which is caused by a configuration conflict between MIBSPI and QSPI EDMA.
