I am actually hacking the CAN implementation within the loader to suit
our own needs, I don't believe it conforms to any standard, definitely none of the ones we use. I believe after reading all the info I could find on the subject that using 2 builds provides greater flexibility for future, as the actual flash Bootloader is not resident it can be modified and sent to customers without recalling units. Of coarse you still have the limitation that the lrae is resident. I am in the process of creating the PC app to drive the Bootloader, I haven't as yet tested this but can't foresee any problems with what I know already.

I had a cursory look under the hood and see two builds - one for the flash the other for sram. Could not a single bootload sector have been feasible using a stack copy scheme for the flash programming func? What server side issues do I need to consider? _____ > Service. ********************************************************************** This message contains confidential information and is intended only for the individual named.
