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

The SD card is inserted, and so far has been written by hand by removing it and putting it a computer to upload the latest firmware.

Since the BTT Octopus is listed in various versions as supported by the flash-sdcard.sh script, why would this not work?

Not all SD cards work with this method, especially big one like 64GB+. Try different cards and make sure they are properly formatted, e.g. with SD Memory Card Formatter for Windows/Mac | SD Association

You beat me to the reply. I have a number of 4GB (full size and micro) SD cards that I use for firmware updates on various printers/boards.

Maybe @Cyberwizzard has an old camera or phone that has an SD Card he can salvage or maybe a dollar store would have some he can try.

If I remember correctly that script only works with boards that use SPI and not DIO. I don’t think the Octopus boards use SPI for interfacing with the SD card.

Should work: https://github.com/Klipper3d/klipper/blob/6749985302fe002a9cb5672dab9badb11e4e3c36/scripts/spi_flash/board_defs.py#L61

I ran into the same error you were getting on this post. Based on what was discussed in this thread I went on an adventure to find the oldest microSD I could find. I tracked down a 16GB card. Once it was installed into the Octopus board. I was able to push the firmware using the flash-sdcard script. Thanks for the info.
