Hi all,
PYNQ 2.7
Board Custom
I guess there are previous posts mentioned dtbo and overlay loading with driver accordingly.
During development, a dtbo is successfully load and driver is mounted:
After dtbo loading, device like WIFI SDIO and no longer working.
I would like to know any possible causes would introduce such behavior? @stf @marioruiz
