Probably more suited to ask on a forum topic than the discord
- I have already flashed klipper successfully on an btt skr v2 mainboard
- I wanted to upgrade the firmware on the sd-card (so pin PC13 is always high by default and my fans turn on when the power is on).
- I’ve tried using the flash-sdcard.sh script
- Although the board is not listed when running
/klipper$ ./scripts/flash-sdcard.sh -l
, I believe the configuration of the board should be the same as the one for btt-gtr (spi1 and PA4 for CS) - schematic from the skr v2:
- The script connects to the MCU but I get an error “SD Card Flash Error: Failed to Initialize SD Card. Is it inserted?” …
SPIFlashError: Failed to Initialize SD Card. Is it inserted?
Would there be advice if I should be using any other pins or if there is some more fundamental issue?
(if it matters, I’m running klipper from a debian 10 based computer, not from a pi.)
thanks!
