Hi Flavio, I followed your tip of comparing with the nuttx standard building steps and it did get me further. I saw that there are some startup objects (nuttx-export/startup) that I did not add in the linking phase. There are none for the stm32 export.
I'm still getting errors but I'll investigate it further and get back here if I'm stuck or done. Thank you!
