SKR-Pro 1.2 Hardware Reset

[Nixdat]

Hi There,

Hopefully I'm posting this in the correct forum if not please let me know

 

Back in Novemeber 2022, I purchased an SKR Pro v1.2 I finaly got around to setting it up but coming up against a couple of odd issues. 

 

It seems the Hotbed and Hotend2 MOSFETs are working opposite to what I require. I've tried to adjust the firmware to compensate for this but to no avail. It seems at startup the Hotbed and second Hotend start heading automatically then when I set a temperature the MOSFETs switch off which is very odd.

 

I would like to hard reset the board and reload the bootloader to maybe reset the MOSFETs. I've researched the process and it seems quite simple but need a copy of the bootloader firmware. Is this something available to download?    

 

I've added two images showing the MOSFETs for the Hotbed and Hotend number2 active but with no temperture on either set.  

 

Thank you for your asssitance

Update to my issue and for anybody with the same error seems like my board was faulty. BigTreeTech replaced the board under warranty
