The LPC54S018M HAL had three critical SPIFI controller issues preventing
flash write/erase operations from working, which blocked wolfBoot_success(),
wolfBoot_update_trigger(), and the firmware swap:
1. Wrong memory-mode read command: Used opcode 0x6B (Quad Output, serial
address) but the boot ROM configures 0xEB (Quad I/O, quad address) with
MCMD=0xEB930000. The mismatch caused garbled address bits when re-entering
XIP after flash operations, crashing on instruction fetch.
2. SPIFI POLL mode not waiting: The boot ROM leaves CLIMIT[7:0]=0x00 which
makes the hardware POLL comparison always succeed immediately. Set
IDATA=0x00 and CLIMIT[7:0]=0x01 to properly wait for flash BUSY to clear.
3. SPIFI reset clears CTRL/CLIMIT: The reset used to exit memory mode clears
the boot ROM's timing config (CTRL=0x600F03E8) and cache limit
(CLIMIT=0x08000000). Save and restore both registers around every reset.
Additional changes:
- Add RAMFUNCTION memcpy (src/string.o) to test app for SPIFI XIP safety
- Add bare-metal UART driver for Flexcomm0 (non-blocking, skips if FC0
doesn't respond — observed on some LPC54S018M-EVK boards)
- Add DSB+ISB barriers after entering memory mode for pipeline coherency
- Enable DEBUG_UART in example config
- Update test app to follow LPC55S69 port patterns with LED indicators
for boot version and update status
Tested: cold boot, ECC256 signature verify, wolfBoot_success(),
wolfBoot_update_trigger(), and full v1->v2 firmware swap all working.
Swap takes ~60 seconds for the 960KB partition (240 sector operations).
