    Can't set BMI back after change to CAN_BSL

    Hello all,

    I am new to ARM microcontrollers and XMC in particular. I am working with the XMC1403 with DAVE and J-Link Lite through SWD0 without issues so far. I have been able to change the BMI from ASC to SWD0 without problems.

    But I will want to use CAN_BSL eventually and I have changed the BMI to it and I can't make it work. I don't see the ACK frame but this is another issue. Is it possible to set back now the BMI to ASC or SWD0? Now I can't communicate. Is this normal? I don't have the wires but via ASC would it work? Do I need another tool?

    You will need to use the CAN interface to upload a program to SRAM that changes the BMI from CAN_BSL to SWD0...
