Hi everybody, I don't know why my design won't run normaly, only PC13 led blink?
I use gd32f1_generic_boot20_pc13.bin so, I can't find any usb devices.
I work with gd32F103CBT µC, the only things differents on the real test design : all resistor 510R are changed to 1K and 22R are changed to 27R....
What's wrong ?
Thank's

Roger eventually pulled support (menu option listing) from GD32F103.

Maybe someone in the forum has some knowledge to assist with the GD32F1xx chip. I never went down that dusty road

I found my errors, I used 8Mhz crystal osc and don't have decoupling capacitor on 5V USB pin...
Thanks
