DfuSeDemo.exe vs STDFUTester.exe

i have made a custom pcb for the stm32f407, all works great :)

but i can only use STDFUTester.exe to download the firmware in dfu mode. DfuSeDemo.exe says success but transferred bytes is 0 and it does not download the firmware.

But..

one time i had it where DfuSeDemo.exe worked corrected and STDFUTester.exe would not work.

But now its back to just STDFUTester.exe works.

very strange hehe. I create the .dfu file the same way each time using DfuFileMgr.exe. I cant seam to work out what's changing to cause DfuSeDemo.exe not to work but some times it does? and if DfuSeDemo.exe does not work STDFUTester.exe does work.

Any ideas?

Thanks :)

broke it now :(

it shows up as a device in STDFUTester.exe

and download looks ok

but it will not run my program any more :(

not sure what iv done? i did press the erase button at some point. could this have harmed it some how?

no idea how i have caused this. it will not load new firmware. yet it shows up in the STDFUTester.exe fine.

Edit:

phew got it working again

i did not make any changes to the firmware, using the same .dfu file. it just decided to start working again now using DfuSeDemo.exe. i have no idea whats going on and why these programs are so random and unreliable hehe
