Firmware Flashing Issue
New Prusa XL single-tool. Front panel says firmware version is 6.0.0+14794.
Latest version of Prusa web site is 6.1.3.
So I tried to upgrade. I downloaded prusa3d_fw_XL_6_1_3.bbf and copied it to USB drive. Then I inserted it in Prusa XL and reset.
No upgrade.
I tried power cycle. No upgrade.
I pressed the control button while resetting. No upgrade.
I tried pressing the control button repeatedly during boot. A couple of times I got an error message saying no firmware file was found.
After several attempts at this I got lucky and for some reason it found the firmware file an upgraded. Not confidence inspiring.
RE: Firmware Flashing Issue
If the version you are trying to load is older or the same version currently running, it will simply ignore the "upgrade".
RE: Firmware Flashing Issue
PrusaConnect is able to flash earlier versions of firmware, use the drop-down list from the lightning bolt icon on the Settings tab.
