STM b_u585i_iot02a MCUboot crash #49056

Closed JiiZR closed 2 years ago

JiiZR commented 2 years ago

Describe the bug MCUboot crashes with latest Zephyr codes.

I: OSPI flash config is OPI / DTR E: BUS FAULT E: Precise data bus error E: BFAR Address: 0xff0000cc E: r0/a1: 0x00000000 r1/a2: 0x2000002c r2/a3: 0x00000000 E: r3/a4: 0x00800000 r12/ip: 0x00000001 r14/lr: 0x08003825 E: xpsr: 0x69000000 E: Faulting instruction address (r15/pc): 0x08005b8c E: >>> ZEPHYR FATAL ERROR 0: CPU exception on CPU 0 E: Current thread: 0x200001b8 (unknown) E: Halting system

First I tried to disable OSPI driver from menuconfig (STM32 Octo SPI Flash driver) but there is some linking problems: c:/gnu_arm_embedded/bin/../lib/gcc/arm-none-eabi/10.3.1/../../../../arm-none-eabi/bin/ld.exe: zephyr/libzephyr.a(flash_map_default.c.obj):(.rodata.default_flash_map+0x5c): undefined reference to `__device_dts_ord_97' collect2.exe: error: ld returned 1 exit status ninja: build stopped: subcommand failed.

Then I disabled chip, \bootloader\mcuboot\boot\zephyr\dts.overlay:

&mx25lm51245 { status = "disabled"; };

and after this MCUboot boots OK. This is workaround for this crash.

To Reproduce Steps to reproduce the behavior:

  1. west build -p auto -b b_u585i_iot02a boot\zephyr
  2. west flash

Expected behavior boot without crash

Booting Zephyr OS build zephyr-v3.1.0-3576-g6825d8412340 I: Starting bootloader I: Primary image: magic=unset, swap_type=0x1, copy_done=0x3, image_ok=0x3 I: Scratch: magic=unset, swap_type=0x1, copy_done=0x3, image_ok=0x3 I: Boot source: primary slot I: Swap type: none E: Unable to find bootable image

Additional context

FRASTM commented 2 years ago

Could be a bootloader/mcuboot/boot/zephyr/boards/b_u585i_iot02a.overlay file made of

&mx25lm51245 {
 status = "disabled";
};

This overlay file is found by build operation : _Found devicetree overlay: ../boards/b_u585iiot02a.overlay

After anaylis of the crash, it appears this is a duplicated of https://github.com/zephyrproject-rtos/zephyr/issues/49715: After initialization of the OSPI driver, the stack is corrupted with elements of the SFDP table:
