Remote updating Arch Max

Hello,

is it possible to update the program of an Arch Max without the connection to a computer, eg. downloading it from internet or getting it from USB-stick or SD card? I guess with LPC1768 its possible via LocalFileSystem Class, but that library seem only to work on some few old platforms.

Anyone have an idea how to do this? Any information is helpful.

Thanks, Michael

Have a look at for example https://developer.mbed.org/users/ebowles/notebook/freescale-bootloader-fota-firmware-over-the-air---/ and http://developer.mbed.org/users/Sissors/code/Bootloader_K64F/.

That is for another MCU, and it for sure won't be trivial :). Doing it offline might be easier than online (due to more compiler options for memory locations).

Thank you, i will have a try. But with offline compilers i had no luck so far, i was looking for a free toolchain, but installing and setting up didnt work for me with windows7

The easiest way would be to have an external flash IC (or other storage), and use your main program to download it in whatever way you want to that IC, and then only let the bootloader grab it from there and program your MCU.
