cannot flash firmware.bin and cannot update bootloader?

[spikar85]

I’m reaching out for assistance with my BTT Octopus Board. I’ve been encountering some issues flashing the firmware.

Specifically:

When attempting to flash firmware.bin via the SD card, the file does not seem to change to FIRMWARE.CUR.
I've tried different SD Cards... same issue.

A suggestion from an online forum indicated that this might be related to the bootloader.

I followed the steps outlined in the DFU update guide to update the bootloader (link: DFU Update Bootloader Guide). However, I am now unable to establish a connection via USB-C. Despite trying multiple USB cables and ports, I keep receiving a "No DFU Detected" error.

Could you provide guidance on the following:

• Any troubleshooting steps for the "No DFU Detected" issue?
• Possible reasons why the firmware is not switching to FIRMWARE.CUR?
