I develop the firmware for our product which uses a LPC1769 CPU with LPCxpresso. We have a development project with a customer who would like to be able to update our firmware on his own, i.e. I would like them to be able to download a new .axf that I could send them by email.

Can anyone recommend the easiest way for this to be done? I don't want to disclose my source code, so I don't want to give them the full LPCxpresso project. I'm basically looking for a utility that would just program the .axf, nothing more. Any tips?

cheers
Martin

If they have the LPCXpresso IDE you can just give them the .axf file (or convert it to a .bin file by right-mouse clicking on the .axf file) and then they can use the 'Program Flash' toolbar button (or Binary Utilities > Program flash) to upload it to the LPC1769.

Alternatively, if they have a USB-RS232 adapter they could connect UART0 of the LPC1769 to a USB port on their PC and use the FlashMagic utility (from Embedded Systems Academy) to upload a .hex file. You can find instructions on how to create a .hex file for your executable by searching this forum for 'How to create HEX files'.
