# CPU : Freescale P1020 (PowerPC e500v2)
# Tools : UART console · JTAG · cross-toolchain
# Outcome : FULL RECOVERY + EXTENDED FIRMWARE ✔
# Steps:
# [1] Serial access via UART (115200 baud)
# [2] U-Boot interrupt → custom bootargs
# [3] Flash dump → reverse engineer partition table
# [4] Rebuild rootfs with Buildroot (PPC target)
# [5] TFTP flash + bootm → system alive ✔
