Problem with STM32F401CCU6 board

[Totouan]

Hello, I am working on a diy simracing project which use the STM32F401CCU6 board. I just bought this board and It worked fine until today for a reason I ignore. The board is stuck on the red led, the blue led doesn't light up anymore. I can still find the board in the device manager ( picture under ) but not it is not detected as it shall be in game controller configuartor ( picture under ). I can still erase the sketch on STM32 Cubeprogrammer and upload it but when I disconnect it it stays with the red led.

Have anyone any idea on what to do ?

Thanks you for your answers, and sorry for my english which isn't very good !

What board?

If not an ST board, give link to full description, schematics, etc.

Where from?

[Totouan]

I bought this STM32F401CCU6 board on aliexpress : https://fr.aliexpress.com/item/1005006127532207.html?spm=a2g0o.order_list.order_list_main.28.29545e5bxmk3BU&gatewayAdapt=glo2fra

So (almost) certainly not a genuine STM32

[Totouan]

But does it really change something ? There aren't any other option than to buy a real one ? No idea of what to do anyway ?

It means the chip may not function correctly

That would be the best route if you want to avoid a load of grief!

eg, see:

That picture shows that it is stuck in Bootloader mode - ie, it's waiting for you to download firmware.

Because it's stuck in Bootloader mode, it won't be detected as a game controller - or anything else - until you've successfully loaded good firmware.

Okay thanks for your time and answer !

[Totouan]

And do you have any idea of how to unstuck it from the bootloader mode ?

[Andrew Neil]

Load some code into it!

You'll have to find out what app(s) is/are required to do that.

Or use an ST-Link (or similar) to program directly.

Okay thanks a lot !
