Title: ISP failure
Post by: GONG Wei on August 15, 2005, 12:12:47 am
Hello everybody,

I'm gonna use an ARM processor to update my 89LPC936 firmware via ISP, I tried break detection to enter ISP mode, but after sending all the records in a hex file to the MCU, the MCU could not boot up any more. BTW, ARM received '.' for each record, did it mean all the records were correctly handled by MCU? Currently I'm suspecting the way ARM interprets a hex file is not completely correct, can anybody provide some clue or suggestion? source code especially preferred. :-)

Thanks in advance.
Best Regards.
