Hello @AsierMaser
MBDT is built on top of the RTD MCAL, so indeed the default configuration project we provide for the peripherals and processors we enable, as well as the APIs exposed inside our Simulink blocks, are based on this layer of the drivers package.
Unfortunately, I am not aware of any straightforward manner in which you could port the low level drivers configurations to MCAL components.
However, my suggestion would be to start from the default configuration project that MBDT provides for the processor your custom board is using, and try reconfiguring those settings to match your design particularities. Could you please share with us what hardware platform are you using, so that we could point you to the necessary documentation? We are describing the process of building specific configuration templates for custom hardware designs inside our toolboxes Release Notes documents.
Thank you,
Irina
