I have managed to get OWL2/3 PCB and schematic file from following link.
I generated gerber file from GAGLE PCB design software and placed order for samples PCB to JLCPCB.
Hope this PCB design file is latest and working one.
As per my understanding OLW2 & OWL3 uses same PCB only difference is CPU.
OWL2 uses STM32F439ZGT6 and OWL3 uses STM32F756ZGT6.
Please correct me if I am wrong.
Now my point is STM32F439ZGT6 & STM32F756ZGT6 chips are very expensive and also not available in our market, But I have managed to arrange STM32F429ZGT6 (OWL2) and STM32F746ZGT6 (OWL3) instead, from our market.
Now my question is how to build Openware for STM32F429ZGT6 (OWL2) and STM32F746ZGT6 (OWL3) instead chip STM32F439ZGT6 & STM32F756ZGT6.
Thanks & regards
