Connect M.2 AI accelerator to STM32MP257F-EV1

[alema416]

Good Evening. I am trying to connect an AI accelerator (ORCA M.2) to STM32MP257F-EV1. I cross compiled orca's driver with the ST developer package and i added it to the device. I also put the accelerator throught a pcie to m.2 adaptor so i can connect it to the device. I get the following situation: 

sudo lsmod | grep cda
