Guide: how to flash ATtiny13a based drivers (NANJG, QLITE, etc.) with custom firmware

[Flashy_Mike]

@adrianoab1

Just another question: i have a driver like this BLF X6 X5/ Taschenlampen-Treiber Astrolux S2 S3 SS SC Sale - Banggood Deutschland-arrival notice-arrival notice on the way, and i’d like to use it with Crescendo, since it is based on an ATtiny25V and should support the full feature set of that firmware. Is there a way to back up the firmware currently on the driver, before flashing a new one? I know i could simply build and flash the Bistro firmware in case something goes wrong, but i’d like to play safe.

If Banggood hasn’t locked the Attiny and didn’t block the programming interface - yes. They did the latter a while ago, I’m curious if it’s still the case:

Banggood BLF X6 driver not programmable any more

Just got a couple of new Banggood BLF X6 drivers and it appears they are not programmable any more. AVRDUDE reports “target doesn’t answer”. It appears they messed up the fuses (or did it intentionally) and disabled serial programming. The layout is also altered, this might also be the cause for the programming error. I guess the manufacturer of this drivers changed. I fear we can’t use this driver currently for own firmwares.

Regarding your first problem: double check if you have set the proper fuses!
