What happened with spindle pwm?

[fitch22]

OK, I will admit I have not built grblHal in a while. Today I updated my repository, but also STM32 Cube got updated as well. I built new firmware. Was looking at the PWM output and needed to change the frequency as I have a pwm to dc board that only works up to 3KHz. So I think I accidentally set $31 to 12000 and I should have set $30 to 12000. Anyway, PWM output was working, but when I try to change $31 and $30 to 0 and 12000, I get error:53. I power cycled, no change. Now it looks like all spindle related options are not showing up at all, even with $+. ioSender shows no spindle related settings.

Any idea what happened? How do I get out of this, or do I need to reset the flash?

Thanks.

Which board map?
Can you check driver.c after an Index > Rebuild to see if hal.driver_cap.variable_spindle = On; is compiled in, I get:

If not the PWM settings are not available reulting in error 53.

Hi Terje,
Board map is btt_skr_2.0_map.h.
My driver.c looks just like yours.

So, I solved it by erasing the flash and reprogramming. I am now able to see all the spindle option settings once again and can change the pwm frequency and duty cycle.

Could this be because the flash layout changed?

Thanks,
Bill

No - I do not think so. Corrupted RAM? There is a check for variable spindle capability here.
