I recall reading that the v1 shims (which I have) didn't include those pins for boot load, so I had to ground GPIO0 and then momentarily ground the reset pin for the process to work with the espFlasher. When I tried the same process with the IDE, writing could only get halfway before it crashed out with an error message. At the time, I didn't record the message, but if it's helpful I can try that again to reproduce it. To confirm, is it correct that in order to flash the ESP01 via the IDE it's required to ground GPIO0 and then momentarily ground the reset pin, or is it sufficient to just ground the GPIO0 (which is what I recall reading, but that didn't work either as reported before). Thanks for the v2 info, I'll give that a go later.
