+###########################
+Musca-S1 Platform Specifics
+###########################
+
+****************
+DAPLink Firmware
+****************
+The code on Musca-S1 is running from embedded flash. Make sure that the DAPLink
+FW for QSPI/MRAM is downloaded to the board. You can find on the
+`Arm Community page <https://community.arm.com/oss-platforms/w/docs/463/musca-s1-firmware-update-qspi-mram-boot-recovery>`__
+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.
