esp32 build broken with version 1.12.6

[dc6jn]

Hi, it seems to me that with changes made from v 1.12.5 (d5daf2e1) to 1.12.6beta (38586cea) my esp32 build crashes with a

Guru Meditation Error: Core  1 panic'ed (LoadProhibited). Exception was unhandled.

My guess is that with the changes made to the stepper driver things got broken. Thanks!

found a possible cause (and solution): configureHemisphere(inNorthernHemisphere, true); is called several times

• https://github.com/OpenAstroTech/OpenAstroTracker-Firmware/blob/cc6fb8ea272936550f65795791bf4e60d7955107/src/Mount.cpp#L212
• https://github.com/OpenAstroTech/OpenAstroTracker-Firmware/blob/cc6fb8ea272936550f65795791bf4e60d7955107/src/Mount.cpp#L269
• https://github.com/OpenAstroTech/OpenAstroTracker-Firmware/blob/cc6fb8ea272936550f65795791bf4e60d7955107/src/Mount.cpp#L269

The problematic call seems to be in line

• https://github.com/OpenAstroTech/OpenAstroTracker-Firmware/blob/cc6fb8ea272936550f65795791bf4e60d7955107/src/b_setup.hpp#L312 while the corresponding driver is initialized starting at line 333:
• https://github.com/OpenAstroTech/OpenAstroTracker-Firmware/blob/cc6fb8ea272936550f65795791bf4e60d7955107/src/b_setup.hpp#L333

So I deleted all calls to configHemisphere and only call it afterwards @ line 349. https://github.com/OpenAstroTech/OpenAstroTracker-Firmware/blob/cc6fb8ea272936550f65795791bf4e60d7955107/src/b_setup.hpp#L349 mount.configureHemisphere(inNorthernHemisphere, true);

Can someone please check if I missed something?

With these mods my eps32 build runs. Thanks

Could you verify this with V1.13.3, please?
