[Ovmsdev] Crashes while flashing

[Michael Balzer]

Craig,

there's a new idf 3.3 config against the starvation, did you set that?

Your sdkconfig should have this:

CONFIG_SPI_FLASH_YIELD_DURING_ERASE=y
CONFIG_SPI_FLASH_ERASE_YIELD_DURATION_MS=20
CONFIG_SPI_FLASH_ERASE_YIELD_TICKS=1

Those are the defaults, working for me.

Regards,
Michael

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.
