I’ve tried different download tool, different versions of the ESP library (2.5, 2.6, current), different versions of IDE (includig beta), added wiring to my downloader tool to include RST and CTS, tool already has switches to turn power on/off and ground GPIO0 to boot into flash mode. Is what is odd is that occassionally after a reboot it all works for a single upload, and this applies to firmware load as well (espressif 3.6.8 download tool), I assume they both use same esptool.py? I’m having exactly the same problem, FTDI connection hardware and ESP parts were working OK on a previous machine, I migrate to a new machine (both W10) and I get the same error.
