Hi,
I need to run an ISP sw upgrade of LPC1768.
Data will be sent through UART by a DSP processor.
What are the commands I need to send to LPC1768 before sending all the programming data?

Regards
pietro

Thanks, but is there any example code?
I may start running and ISP code upgrade sending data from an LPC1768 to another LPC1768.

Regards!

No Smile

Since that part is usually done by a PC software it could be a good idea to read a working program like FlashMagic Shock
