When i compile the dfuproalgo example add a header with DFUSec and dowload it to my own board the programmer complaints "Board algorithm failed to start".
When i'll use a precompiled file "iram_dfu_util_any.bin.hdr" the programmers works OK, but i want to add a NOR flash part to the downloader.
I'am working with Keil V5.0 en LPCopen 2.09 on a own LPC4357 board.

Does anyone have a clue?

Thanks,
Allard van Woerkom

Did you run the image via the header generation tool first before using it as a programming algo that is downloaded?
That is the first tab in the DFUSec tool. Use the file it generates with your binary as an input as the algo file for the program tab.

If all else fails, try rebuilding the original algo "as is" and then using it to make sure it works. Then start small - maybe just stubbing in your functions without actually altering hardware before adding in the full functionality.

Hi kevin,

Thanks for your quik reply.
Yes I added the header to the algo file, and I use the example files without any changes.
Still does not work.
See the two screenprint's of the action's i made.
