Flash-sdcard fails for creality 4.2.7 board

Basic Information:

Printer Model: Ender 3
MCU / Printerboard: Creality 4.2.7
flash-sdcard.log (2.1 KB)
Klipper v0.11.0-271-g5f990f93

Describe your issue:

I’m trying to flash Klipper directly from the Pi to the Ender3 with a silent mainboard using the flash-sdcard-script. Both are running the latest version and I’m using the same sd-card that I used for flashing Klipper manually (FAT32 / MBR-Partition table / 1GB).

This is the command I use:
./scripts/flash-sdcard.sh -c /dev/ttyUSB0 creality-v4.2.7

The reset works, but writing the file to the card fails with FR_NOT_READY

Any hints what could be wrong?

Try different SD cards. Some seem problematic. Also try formatting them with SD Memory Card Formatter for Windows Download | SD Association

Tried a couple of cards and got it working, thank you for the hint.
The ones that did not work were non-HC-cards, so maybe that’s an issue
