The PolarFire SoC's system controller offers the ability to re-program the FPGA from a user application via two, related, mechanisms. In-Application Programming (IAP) is not ideal for use in Linux, as it will immediately take down the system when requested. Auto Update is preferred, as it will only take affect at device power up*, allowing the OS (and potential applications in AMP) to be shut down gracefully. * Auto Update occurs at device initialisation, which can also be triggered by device reset - possible with the v2023.02 version of the Hart Software Services (HSS) and reference design.
