I was a little away from Eevblog because of some personal problems.
Nice work!
Thank you very much
Well I went into this thread once again, this time because I was having problems updating my ST42 so it's funny that you say "hope you are the only unlucky guy who has this problem" because I'd like to introduce myself: Hi, I'm another unlucky guy, it seems :/ I'm getting exactly the same error, and I'm not really happy to hear it's a hardware problem. Is replacing the chip the only solution?
EDIT2: I would like to add that I remember updating the firmware when I was having the screen glitches (which I also reported here). And I don't remember the process giving me errors that time. Maybe this is not necessarily a hardware problem (in my unit at least) but rather that the sofware gives the same error under different conditions (including faulty hardware).
EDIT3: Ok, "solved" the issue and I'd like to keep a record here despite being a very silly mistake from my part. Apparently the intimidating error shown by the updater is the same in case of any problem communicating with the device. In my case it was either a driver issue or a cable issue, because changing the cable and usb port I got it to work.
BUT I also got the same error during one attempt in which I didn't enter into bootloader mode correctly. The COM port appeared on my computer but it wasn't in *actual* bootloader mode.
So I'd like to leave this post here as a warning for others: Even if you get the same error, it does not mean it's a hardware error. As obvious as it is now, the firmware updater will give the same error in any case in which the device is not responding back.
I'm happy to read that, as it was finally only a software/setting problem
For me, the RX pin of the chip was shorted to ground
Since I put the new one, no problem at all
For @shannon: I have checked the new diode signal: it is now super clean
I have not used it a lot since my fix, so I don't know what is new in the 1.54 version ?
@Shannon: Do you have a changelog or something like that ? With that, I can continue to suggest some ideas I could have
