Nice to hear, that someone else could use the solution. I tried with a resistor due to safety reasons - it works as current limiter and prevents damages. I reported to use a resistor because it worked for me.

I tried all pins to find the reset pin. The board seemed to perform a reset and programming startet automatically with the programming tool waiting for the board. I found that holding it down enabled my board to complete the whole programming procedure.

Ok, fine. I started the programming as Goucho told first. Then I found, the pulling this pin to GND the unit restarts, so I thought it is the reset. Letting the pin float brings the same CORRUPT result as described. Holding it down enabled the unit to be programmed, just with the running...

Did you try my solution?

Power is ok, cable almost doesnt matter as 115200 kbs.

Hi guys, I found a solution (partly by accident) when I was searching a reset pin for the board. Just to eleminate the chance of transient power issues short after powering up the unit. To solve the "CORRUPT" message described above, I pulled the marked pin to GND by a 8.5k resistor. No...

Thanks for your reply, I am still investigating, it seems there is a solution....

I use a lab power supply with thick cables, the air unit pulls just 250 mA. Or do you mean the TX/RX cables? I was investigating this and tried shorter cables, other GND connection and more. Investigating the RX TX signals, I found something strange... The blue curve (CH2) is what the air unit...

Hi, i did everything as described in your post to solve the firmware problem by reprogramming the images. But it failed. I tried several times, sometimes the CRC is transmitted, one I saw the ULB was transmitted. But usually it comes to this output...
