PYNQ powerup boot fsbl or overlay ambiguous

Image: PYNQ 2.7 or 3.0.1
Board Custom

It is understand that the boot process will not load any overlay unless FSBL is customized.
This is due to base overlay and driver mismatch will result in stuck.

However, there are inherent driver like i2c based device drivers.
Just clearing, if inherent kernel only uses ARM MIO interface there should not introduce any driver issue when detecting the device

When comes to PL EMIO interface there, driver could be problematic due to missing PL bitstream loading and hence the EMIO is not able to route to FPGA PL BANK IO.

So any way to make the bootup IIC device is always probing correctly?

Thank you
