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 :)2012-12-02 07:50 AM
broke it now :(
it shows up as a device in STDFUTester.exeand download looks okbut 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?2012-12-02 08:24 AM
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 againi 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
