Hi, thank you for you answer.
I have other problems.
- When I try to program with the recommended cable, it recognizes the serial port, then I proceed to load the .Hex file, but when I give it the option to write the program, it is blocked. You can see in the image, what can I do to identify the error? I was Check that the input voltage is 3.3v and in Vout there is 1.5v.
Since this uses a logic analyzer to visualize the signals, in which it can be seen that only a small pulse is seen in the RX pin (which is without or with the card STNRGPF01).
2. Led PFC OK does not turn on:
The Led does not turn on either when the system is energized or when the FTDI module is connected, it only turned on in the first tests but after rectifying some welding points it did not turn on again, the integrated one was changed but it still does not turn on any of the Two occasions.
3. Adapter to program:
Reviewing the manuals we observed that there is a card that makes the bridge between the uart of the integrated and the FTDI module, we implemented that card but there was the same answer and seeing the operation of this we found that only switches the earth of the system so we do not understand how You will receive the signals without having a reference.
These are some of the disadvantages presented, we would like to know what is your opinion given your experience with this system, We appreciate your collaboration.
