5.4 MCH Boot Process
The MCMC boot process includes the following steps:
1. The boot loader performs an early Power-On Self Test (POST) of the hardware.
2. If the FPGA POST fails, the boot loader will try to automatically recover the
FPGA from a failsafe configuration stored in the flash.
3. The Boot Loader calculates the checksum of the MCMC firmware image. If the
checksum is not valid or three consecutive boot attempts have failed, the Boot
Loader performs an automatic rollback to the last working FW version.
4. If a new FPGA configuration has been downloaded through an HPM.1 upgrade
before, the bootloader will automatically reconfigure and reset the FPGA in the
booting process.
5. If the early POST and FW/FPGA update and recovery mechanisms have been
successful, the boot loader passes control to the MCMC firmware by calling its
entry point.
