Hi famo,To make things a bit more (less?) confusing, I actually found that Philippe's guide is slightly less cumbersome to follow, as it only requires one extra java program (apart from the arduino ide). Google translate actually does a good job in translating his step-by-step tutorial:https://translate.google.com/translate?sl=auto&tl=en&u=https%3A%2F%2Fsystemes-embarques.fr%2Fwp%2Ftelechargement%2F
Hi famo,Just running Philippe's FPGABlinkLED_Sketch through the Arduino IDE (with the pre-supplied app.h) produces the behaviour on my Vidor as shown in the attached video. (My LED has a built-in resistor)I did encounter similar problems to what you are describing before (where nothing really happened irrespective of what I was trying to load). For me, this was a firmware issue, I had to restore the bootloader according to the other thread on this forum and then update to the latest bootloader through the Arduino IDE (File->Examples->(Examples for Arduino MKR Vidor 4000)->SAMD_BootloaderUpdater
I confirm: right now I've reinstalled the bootloader using the VidorFPGARecovery files.The Philippe's blinking led now works (!) but my own project stops uploading ad 37%.I remember this 37% has been experienced by someone in the forum, I have to search the thread.Do you know if VidorFPGARecovery is equivalent to SAMD_BootloaderUpdater?
