Board does not boot anymore

[SirPlotalot]

Hello !

Everything went fine with my new skr 1.3 ( Marlin 2.X ( Ender 5 ) for about 20 prints.
Suddenly when i start my printer i get a constant beep tone and
a blue screen ( Stock Creality screen).
So i disconnected everything switched to 5v jumper and tried to recompile the firmware as usual via PlatformIO.
I get the error "board not found". ( But it shows up normally under windows 7 )

• Already tried another sd card, same problem.
• checked fuses
• pushed reset button , nothing happens, red Led is on all the time.

I am thankful for every hint, thank you in Advance !

Did You check fuses?

Hello !
As i wrote, yes. Both.

Disconnect all connectors, remove stepstics and connect directly to PC (switch jumper to USB +5V).
If You can't connect via serial port try to use board UART directly (AUX-1) to PC or by OctoPrint/ESP3D.
If mainboard is OK You should get some information on console.

Hello Artur,
connected the board via UARt to Octoprint. Trying to connect fails because no manual baudrate works, Auto baudrate brings up this :

Connecting to: /dev/ttyAMA0Changing monitoring state from "Offline" to "Opening serial port"Connected to: Serial<id=0x6abad110, open=True>(port='/dev/ttyAMA0', baudrate=115200, bytesize=8, parity='N', stopbits=1, timeout=10.0, xonxoff=False, rtscts=False, dsrdtr=False), starting monitorStarting baud rate detection...Changing monitoring state from "Opening serial port" to "Detecting baudrate"Trying baudrate: 115200

looks like some boards have the EXP1 and EXP2 bad oriented, check the pinout to confirm.
In my case, I had to cut the slot space to allow my cable to connect correctly oriented.
