INFO:link UPDI not OK at programming ATtiny1604 #56

Hi, I'm trying to write a hex on ATtiny1604 using pyupdi.py but getting "INFO:link UPDI not OK" The host OS is Windows10 The serial adapter is USB -> TTL.

$ pyupdi.py -d tiny1604 -c COM4 -b 9600 -f Blink.ino.hex -v INFO:phy Opening COM4 at 9600 baud INFO:phy send 1 bytes INFO:phy data: : [0x0] INFO:link STCS 0x08 to 0x03 INFO:phy send 3 bytes INFO:phy data: : [0x55, 0xc3, 0x8] INFO:link STCS 0x80 to 0x02 INFO:phy send 3 bytes INFO:phy data: : [0x55, 0xc2, 0x80] INFO:link LDCS from 0x00 INFO:phy send 2 bytes INFO:phy data: : [0x55, 0x80] INFO:phy receive : [] INFO:link UPDI not OK - reinitialisation required INFO:phy Sending double break INFO:phy Opening COM4 at 9600 baud INFO:link STCS 0x08 to 0x03 INFO:phy send 3 bytes INFO:phy data: : [0x55, 0xc3, 0x8] INFO:link STCS 0x80 to 0x02 INFO:phy send 3 bytes INFO:phy data: : [0x55, 0xc2, 0x80] INFO:link LDCS from 0x00 INFO:phy send 2 bytes INFO:phy data: : [0x55, 0x80] INFO:phy receive : [] INFO:link UPDI not OK - reinitialisation required Traceback (most recent call last): File "C:\python\pyupdi-master\pyupdi.py", line 182, in _main() File "C:\python\pyupdi-master\pyupdi.py", line 95, in _main nvm = UpdiNvmProgrammer(comport=args.comport, File "C:\python\pyupdi-master\updi\nvm.py", line 17, in init self.application = UpdiApplication(comport, baud, device) File "C:\python\pyupdi-master\updi\application.py", line 17, in init self.datalink = UpdiDatalink(comport, baud) File "C:\python\pyupdi-master\updi\link.py", line 32, in init raise Exception("UPDI initialisation failed") Exception: UPDI initialisation failed INFO:phy Closing port 'COM4'

What I am doing incorrect? Seems it supposed to work for tiny1604

Have you set it into programming mode with a 12V pulse?

margemag commented 4 years ago

No, I haven't set it into UPDI mode with 12V pulse but I think it already in UPDI mode as I can flesh in it using Arduino / megaTinyCore.

What is your updi setup?

& how did you flash the arduino bootloader?

margemag commented 4 years ago

I am not sure about flashing the Arduino bootloader, but until now I am using Arduino without issues to flash on tiny1604. As tiny1604's doc says "UPDI is based on standard UART communication, using a fixed frame format, and automatic baud rate detection" I think it had to work with programmer's set baud rate, or I am mistaken. Can you tell please how can I get details about UPDI setup?

As tiny1604's doc says "UPDI is based on standard UART communication, using a fixed frame format, and automatic baud rate detection" I think it had to work with programmer's set baud rate, or I am mistaken.

You are correct - it should auto-detect the baudrate from the serial device.

By UPDI setup I meant that have you connected the serial adapter as shown in the README of this repo? What serial adapter are you using? Have you tried different baud rates?

An alternative could be to use an arduino as the uart serial bridge https://github.com/SpenceKonde/megaTinyCore/blob/master/MakeUPDIProgrammer.md

Finally I would recommend this programmer https://www.tindie.com/products/leonerd/avr-updi-programmer-with-12v/ (it's unfortunately out of stock but all the files are open source)
