Hello I have the STM32 F103 MCU, I downloaded the f103 fimware and it crashed the black screen. What I can do? help
@Tim Houser
Is there something wrong with your machine? Why do you need to update the firmware? Do you think it’s fun to flash the firmware? I’m not sure what’s wrong with you, but the suggestion is to buy a new KP3S motherboard, which comes with the latest version of the firmware.
@KINGROON Office you need to fix the link to the gd32 firmware. It points to the 407 firmware. Basically the 103 and gd links need to be the same and as of this reply they are still wrong. Please and thank you.
@Luke
MCU GD32 F303 version firmware is used 103
@Kubi
Hello, you try re-flashing the firmware.
