Hi,
full disclaimer: total newb and trying to dig my way into the matter 
After some successful OTAs the Sonoff Touch with Firmware 1.70 should be my first FTDI flash. However, I won’t get arendst’s current tasmota uploaded. I already did
- by another FTDI (now standard FTDI 232-based)
- soldered the pins
- changed the cables
- switched to current Atom with current platform.io
but I still receive the following error message after a successful build/compile:
