[StartupKit_Xylo] USB program and FPGAConf

Hi Daixiwen,

does fpgaconf might change usb interface during upload ?

Because, I try another program which only blinks leds (without USB communication) and it works when I program it in the FGPA's SRAM (I use the button "Program Boot-PROM" of FPGAConf). So I can power off then power on my board and the program is still running :)

But when I upload a program that use USB communication, it does not work... :(

SO, I suppose there is something happening during the configuration of FPGA (button "Configure FPGA of FPGAConf)

Yes, I have read the documentation that you can find here :

Have you good an idea ?

Thanks a lot !
