[Ovmsdev] Crashes while flashing

Really no idea. I’ve seen cases of the wifi getting messed up during flash erase (bug in esp idf as it starves the wifi stack during the long erase operation, and supposedly fixed in the 3.3 we are now using).

Can you copy off the elf before doing the build/update, so you have that to decode the backtrace?

Regards, Mark

Several times this weekend I've gotten "Request error, please retry" when starting the flash. Just now I got one half way through the flash. I haven't been able to get a useful stack trace because my build/ovms3.elf has already been overwritten with a new image when this happens and xtensa-esp32-elf-addr2line just prints a bunch of "??:0" lines. I've had this multiple times on two different modules today and so far 3 times in a row. I finally resorted to booting from the factory partition (which I try to keep loaded with the current public release). That resulted in it completely losing its config and firing up the OVMS ssid instead of joining my network.
