# PolarFire SoC MPFS250T M-Mode (Machine Mode) with SC QSPI Flash
|
|
#
|
|
# This configuration runs wolfBoot directly from eNVM in M-mode (Machine Mode),
|
|
# and boots a test application from SC QSPI flash to L2 Scratchpad (no DDR).
|
|
#
|
|
# Boot flow:
|
|
# 1. eNVM (0x20220100) -> L2_SCRATCH (0x0A000000) - wolfBoot starts
|
|
# 2. Load signed app image from SC QSPI flash to L2_SCRATCH (0x0A010200)
|
|
# 3. Verify signature and boot
|
|
#
|
|
# Flash using mpfsBootmodeProgrammer (bootmode 1):
|
|
# java -jar mpfsBootmodeProgrammer.jar --bootmode 1 --die MPFS250T \
|
|
# --package FCG1152 --workdir $PWD wolfboot.elf
