Describe your issue:
About 3 days ago I started installing klipper in a old machine that I had laying around but when I got to flashing klipper it seems its not flashing. I tried switching between different SD cards (FAT32, 4096) but still wont flash (It is stuck on the creality logo screen not the blank that was supposed to) I can flash back to marlin and other firmware. I did follow trough the cfg for ender 3 v2 2020 (STM32F103, 28KiB bootloader, Selected disable SWD for Gigadevice clone, Extra low-level, USART3 PB11/PB10, 250000 baudrate, and changed the .bin file name between flash tries). After that I though it could be that the mcu was just not connecting to Linux, so I followed along another post and disabled modemmanager and brittly. Now it outputs the the path when using ls /dev/serial/by-id/* our by-path (both works) but still saying that it cant connect to the mcu (tried connecting with marlin flashed and it cant recognize the mcu)
Edit: Here it is the dmesg output
