现象: LUP 帧后复位, RST=0x00000000 (无标志) 且 HardFault 打印缺失
(上次 0x10000000=SFT 确认 HardFault 路径, 这次连打印都没有)
方案: .noinit 段复位不清零, 跨复位留痕
- Link.ld: 新增 .noinit 段 (startup 只清 .bss 不碰)
- fault_diag.h: FaultDiag{magic,mcause,mepc,mtval,marker,boot_cnt} + FAULT_MARKER 轨迹宏
- HardFault_Handler: 纯 RAM 写 mcause/mepc/mtval (官方 __get_MCAUSE/MEPC/MTVAL,
不依赖 UART/printf, 栈坏也能留痕) + 尽力打印
- main 开头 fault_diag_init(): 打印上次现场 + 递增 boot_cnt
- 轨迹 marker: 主循环 LOOP_TOP/UART_SRV/SIM_SPI/POLL_BLE + LUP 链
LUP_FRAME/INGEST/EVT_FEED 入口出口, 复位后看 marker 停在哪一步
