Openwrt official dts configuration is NEO (32 + 128), and the BIT5 configuration is (32 + 64), so you need to modify the RAM configuration from the DTS file.

Can I change IoT gateway mode or IoT Device mode (1port/ 5port) in dts?
-
@neige I am still not sure about this.
-
So a BIT5 can be put in a mpcie slot and serves as a PC in a PC? How does it communicate with the PC, just as a wireless device or can it share storage to?
-
@roel
No, biT5 itself is already CPU master, it just uses the NGFF connector.
