Reply To: Firmware Flashing from SD

[DevLatron]

Hi there…

You do have to flash the device once before the SD card upgrade can work as it is basically a firmware feature.

There is a thread here discussing different issues with the blasters. Maybe that Can help you.

Sometimes plugging in the device a couple of times can help. If you manage to get it flashed only once, you’d be able to use the sd card approach for future updates.

Also, make sure you get it to a state where the backlight is on and both leds are lit when assembling before trying to flash.
If you’re based near Germany, we can perhaps arrange that I can flash it for you.
