hi,
compiled Tasmota 11.1 successfully but could not upload it to the shelly 1pm.
Tried two different Programmers one with CPXXXX and one with FTDI chipset as I thought 1st it has something Todo with a missing driver or something like that …
But upload always fails with the following message:
"Use manually specified: /dev/tty.usbserial-AD0JIMIP
Uploading .pio/build/tasmota/firmware.bin
esptool.py v3.1
Serial port /dev/tty.usbserial-AD0JIMIP
Connecting…
Failed to get PID of a device on /dev/tty.usbserial-AD0JIMIP, using standard reset sequence.
…………………_____
A fatal error occurred: Failed to connect to ESP8266: Timed out waiting for packet header"
Any hints? Thanks in advance for your support.
kind regards
chako
