mbed-os-> features-> unsupported-> USBHost
By using the function, I apply it to the product and use it well.
However, if the RAM is too small and I want to use a different board, how do I run the NUCLEO_L496ZG and NUCLEO_L4R5ZI models?
- Add “macros_add”: [“USBHOST_OTHER”] of the model to target.json.
- Add the board to USBHALHost_STM.h
The compilation is fine, but I get the error below. How can this be possible? What’s wrong?
