Just take your cover off and the chip is right there. Or search the forum as it's pretty common knowledge. Unfortunately, it doesn't tell you much (if any) about the actual code. I've got several inverter chips purchased from supply houses as they've been discontinued as I remember. Again, unfortunately, you can't even replace the chip because a new one will not have the Bootloader installed and although the chip mfg provides a basic bootloader the Alta guys modified it quite a bit per typical practice. Trying to figure out all the Alta specific register and memory mapping difference plus whatever else they changed would be, in my opinion, even more important than reverse engineering the inverter code. Without it, as a community we'll never be able to replace a bad inverter processor, ACM processor, DCCP processor(s), BCU processor(s), etc. Note, each module has a different processor and therefore a unique Bootloader. The CAN Bootloaders tell the processor how to communicate with the outside world (via CAN obviously) and are hard installed at the chip or board assembly level before any firmware is loaded via MT (via CAN).
Note: If anyone has access to one or more CAN bootloaders please advise.
