Hi,
The esp8266 bootloader responds to write (command #3) requests with a status and error.
I keep receiving status=1 and error=8 on certain (deterministic, reproducible) packets. Assuming below list this is a "Download Error".
What exactly does this mean? Under which circumstances is this error triggered?
Below is a sample trace which fails for (to me) no apparent reason.
Thank you,
Conrad
