Hello,
As announced on March 3 (see
https://lists.trustedfirmware.org/pipermail/tf-m/2021-March/001516.html) and in the absence of objections, the nRF5340 PDK platform (nordic_nrf/nrf5340pdk_nrf5340_cpuapp) has been deprecated in the v1.3.0 release and the release is the last one to support
this platform.
Today, the code and documentation related to this platform have been removed from TF-M.
Best regards,
Andrzej Gł±bek
