Hi,
I also needed to use the RAppID BL software with my PCAN adapter. Slightly modified the RAppID_BL.exe to make it work with PCAN, binary can be found in the attachment. The app thinks it's Vector so Vector CANCaseXL must be chosen, but it actually sends the messages to the Peak adapter.
I needed this to test to see whether my SPC560P50 will work with the bootloaders in this software. I tried MPC5604/3P, it successfully uploads the BL but then it gets stuck in the Initialization phase for some reason. Been trying to figure out why for a few days but I think I'll give up so I hope this at least works for someone else.
