Musca-S1 Platform Specifics

DAPLink Firmware

The code on Musca-S1 is running from on-chip eMRAM (2MB non-volatile bootable memory). Make sure that the DAPLink FW for QSPI/MRAM is downloaded to the board. You can find on the Arm Community page A short description of how to update the DAPLink FW can be found there as well.

Platform pin service

This service is designed to perform secure pin services of the platform (e.g alternate function setting, pin mode setting, etc). The service uses the IOCTL API of TF-M’s Platform Service, which allows the non-secure application to make pin service requests on Musca S1 based on a generic service request delivery mechanism.
