[Ovmsdev] ESP32/3 benchmark (was: External Wifi antenna)

[Michael Balzer]

Craig,

you triggered the watchdog by pasting all commands into the shell, you 
need to leave 1-2 seconds between the commands to feed the dog.

Your results could indicate the SPIRAM workaround doesn't really degrade 
performance for the kind of RAM accesses the test does.

Or it indicates something's wrong in your build / configuration, i.e. 
the SPIRAM workaround is still in place.

Ideas:

a) Did you do a "make clean" after disabling the SPIRAM workaround?

b) Verify your toolkit version (should be crosstool-ng-1.22.0-97-gc752ad5)

c) Verify the actual compiler & linker options given by doing "make -n"

Regards,
Michael
