while new freescale boards come with the opensda debug firmware, i still students using boards with the osbdm/osjtag. and with new codewarrior tools, it might be that there is a new osbdm/osjtag firmware, and when i download to a board with an older firmware, the tool will prompt me to update the firmware. to me, after doing this several times, not a big deal. but for someone who sees this the first time, it might not be that easy. so to avoid any further questions, here we go with a step-by-step tutorial how to update the osbdm/osjtag firmware.
updating a new firmware
if trying to download to a board with an old firmware, the following dialog shows up:
- keep that dialog open (do not click ok or cancel (yet)). power off the board with unplugging the usb cable. if your board is inside a tower, then best if you remove the board from the tower system.
- locatetheosbdmbootloader jumper on the board. this jumper is *not* set by default. check your hardware user manual/schematicsforthelocation of the jumper. on most boardsthejumperislabeledbtldorbootloader or something like that.
