Skr Pro V1.1 - Software Update problem

Hello everyone,

I would to know if you had the same problem with this board. In first time I had updated some time the Skr pro with the SD card, but now, when I try to update a new one, the process don't work. When I introduce my SD card and put the power on, the board start without to take into account the SD card. So the new software is not load on the board. I try to put different firmware, but it's same thing, no update was lunch by the board...

I share the config used. For information I had already format the SD card in FAT format with the mac and windows system. I use the PlatformIO to compil the software.

Thank you in advance for your suggest.
