Not sure what you mean. This user1 bin file was in the "at\1024+1024" subdirectory--I copied it to where the other files were.At 0X1000 you're trying to upload a file that probably doesn't exist yet
I tried esptool.py. Had to install python--success was reported. When I ran the esptool.py, I was just returned to the DOS prompt. Same with "python version" and "python -h", so there must be something wrong with my python installation (but it doesn't say that it isn't there).
Back to "Ugly and unwieldy" for SDK 3.03 with no success, though "Finish" was reported and the chip info is read. No response to "AT" and just garbage with Reset or power cycle. But if I flash SDK 2.0, all works. Also, with SKD 2.0, all the AT commands I have tried work except for AT+CIUPDATE and AT+CIPSNTPTIME? (I'd like to decode the time).
This is the 4th time I've spent 2-3 hours trying to get the latest firmware into the chip (which is supposed to be SKD 3.03 as I understand it--if so, why doesn't AT+CIUPDATE update to that?).
Is there a response to AT+CIPSNTPTIME? with SDK 2.2.1? Maybe I'll try to install that.
