Hello !
I need to use the Boot Assist Module to boot an application from FlexCan bust to internal SRAM.
Now I'm using the TRK-MPC5604P demo for testing with CodeWarrior 10.5. I set the jumpers (FAB = 1, ABS2 = 1, ABS0 = 0) to set the boot mode to FlexCan autobaud to work above 200kbs (8MHz crystal frequency). But when you restart the MCU and try to send frames to calculate the baud, I can’t establish communication.
What I'm doing wrong? I guess initially prepare the MCU to use the BAM, but using the Reference Manual have not found the way.
Can help me with a example code? Just I have to modify the Linker Files?
Thank you very much for your time!
