I’m having an issue with a build in which the Proffieboard is intermittently not finding the SD card on bootup?
Perhaps four out of five boots are fine, but the fifth boot I get the “SD card not found” message.
There’s a fair bit of space under the board so the wires aren’t bunched up or crowded against the holder particularly.
Battery is fully charged and showing 4.14 volts at battery when it’s removed from the hilt. Also showing 4.14 volts at Batt- and Batt+ pads when the kill key is pulled, both when the saber boots normally and when the SD error is thrown. 3.3 volt pad is also showing correct voltage in both scenarios (well, 3.29 volts).
Stuff I’ve tried:
- A different SD card;
- Kapton tape (thin) on the back of the card;
- Electrical tape (thicker) on the back of the card;
- Reflashed the board;
- Formatted cards with the recommended SD formatter.
Specs are:
Proffie 2.2 (selected in Boards Manager and config);
ProffieOS 6.6
Plugin 3.6.0
2.1mm charge port
Any thoughts welcome.
