Hi,
I use the USBPD Middleware to implement a PD Port with a G474RB. This is functional. Now I would like to implement USB-PD EPR. I cant find any settings that would make cubeMX use the EPR version of the stack, the cubeMX inputs are further limited to SPR ranges.
Is it possible to use USB-PD EPR in cubeMX ? Information that i have found on this topic suggest that X-CUBE TCPP supports EPR, however the TCPP hardware itself does not support EPR anyway. So far I have not enabled the X-CUBE TCPP package since I dont use that hardware. I use a different port protection IC which is rated for EPR operation.
The USBPD stack in the up-to-date G4 firmware V1.6.3 seems to be Version 4.1, which is from 15-Dec-2021. That is before EPR was introduced with Version 5.0
So to summarise : Is there a way to force cubeMX to load the newer library ? Do I have to manually download the new library and link it?
Thank you,
Janik

This seems to be a possible git submodule issue, where the submodule never got updated for the newer releases of the G4 firmware package.
