Unable to erase ATtiny402 #53
Comments
#45 appears to have same symptom? |
Duplicate of #45 Yes, that issue really seems to reference the same problem |
Would #43 help? Worth trying? |
Unfortunately not, as I said, I tried both options |
Alright, a big update: I managed to get into the terminal mode. I hadn't uncommented a line in |
I tried to communicate with the ATtiny402 over UPDI, yet I couldn't. My chips are brand new, I bought them from a very reliable seller. The error message I got after I managed to get the programmer working seemed similar to the message I am supposed to get with a locked chip. I tried to unlock it by erasing it using
-e
flag or by using-F -t
flags, yet none of them worked. I was stuck with the same error message. I am sure that my connections are right, I added a 10uF capacitor on my Arduino Uno to prevent it from resetting (which indeed works), I have copied the.conf
file, and all the code I'm using is the most recent one I can get to. I am running everything on a Linux machine. There doesn't seem to be anything about this particular problem in other issues, not open nor closed, as far as I can tell. I'd really appreciate if you could look into this.The outputs (both verbose and short) of my commands look like this:
$ avrdude -c jtag2updi -P /dev/ttyACM0 -p t402 -F -t
$ avrdude -c jtag2updi -P /dev/ttyACM0 -p t402 -F -t -v -v -v -v
