Flashing SD Card not working

General Discussion
1

Heya, I just tryed flashing my MCU’s SD card with the script provided by klipper.
This is what I have done:

sudo service klipper stop
cd ~/klipper
git pull
make clean
make menuconfig
make
./scripts/flash-sdcard.sh /dev/ttyACM0 btt-skr-turbo-v1.4

it all ends with this:

Flashing /home/pi/klipper/out/klipper.bin to /dev/ttyACM0
Checking FatFS CFFI Build...
Connecting to MCU...Connected
Checking Current MCU Configuration...Done
MCU needs restart: is_config=1, is_shutdown=0

SPIFlashError: Failed to Initialize SD Card. Is it inserted?

and yes it is the right /dev/tty* device and yes the SD card is inserted. Anyone got an idea?

Is it your first time flash of Klipper? You can only use the script if Klipper was already flashed on the board before.

Nope it is installed for about 1/2 a year now

下载pi的klipper.bin改名成FIRMWARE.bin，装到skr主板的sd卡，开机
