Did you use reset pin as detailed in the procedure?Hello Friend. I have an issue with lightbridge air unit flash. I did Lightbridge GS as you said in your thread and it worked, but when i tried to flash Air Unit, it started pretty well, but it stops in 90% when sending first .img file. I tried to do it many times (with/without reset), but its similliar problem every time i do it. Can you help me with it?
Apparently the NAND processor is really blocked. I have done the firmware procedure a hundred times and the result is always the same. The process stops at 90%. And what can replace it? Are there such NAND processors on sale? Any help would be greatly appreciated. I live in Kyrgyzstan, I have one such lightbridge. There is nowhere to take a worker.Hello buddy...its been a while since I last did this procedure. I remember providing step by step ways to reflash the NAND chip. just follow the instructions if it doesnt work then your NAND chip is bricked or unable to get fixed and you must find another wifi 2.4 ghz board to flash. my primary reason of inability to help with precision is due to the fact I no longer have a phantom 2 vision plus to fix. you need to have a complete bird in order to finalice a job. there is no way to corroborate if this fix worked unless you have a way to test.
Thanks for the answer! How can you reprogram the NAND chip? Tell me please. I do everything according to the instructions from the first post. I have never done this. Therefore, I will be very grateful if you teach me how to reprogram the NAND chip!First try to reflow the NAND. Also try running the command while pushing a bit on it, and on the DaVinci processor - if chips need reflow, then pushing on then will have influence on the results, either the flashing will stop further or earlier.
If that won't help - just buy the NAND chip. Here's how I replaced the same chip, on a different board though:
Here is a success story I wanted to share. I had a Phantom 3 Pro gimbal which didn't allowed me to see the FPV feed. Photos and movies were recorded on sd-card, there was just no live video - only grey background - in Dji Go. By connecting another gimbal, I narrowed down the problem to gimbal...phantompilots.com
we use normal supply instead. , not from usbIf you're powering the board from USB, try using normal supply instead.
You may also try reflow the Davinci chip.
Other than that - figuring this out would require checking on which specific instruction the flashing stopped, and what that means. Not an easy route.
