Exception 0xc0000005 (EXCEPTION_ACCESS_VIOLATION)
On a hunch I tried running ESP_Basic_Flasher elevated. This prevented the crash above on clicking Format Flash but it didn't seem to do much. Reflashing the firmware and still no go.
I tried manually running:
esptool.exe -bz 4M -v -cp COM3 -cd nodemcu -ce
It starts to work and then shows two failures to connect. Maybe I have the wrong switches.
I've also read that esptool.exe is flawed in this regard and people have installed the raft of garbage to allow them to run esptool.py for this instead and had success.
