slinky with REBOOT_LOG_FCB, inside log_reboot_pkg_init error

[Louie Lu]

Hi everyone,

I'm now running slinky without REBOOT_LOG_FCB, setting in sysfcg.yml as 0.

And the result from serial is like this:

17:[ts=17000ssb, mod=6 level=4] rsn:RESET_PIN, cnt:18, img:1.0.0.0
Slinky 1.0.0.0
18:[ts=18000ssb, mod=6 level=4] rsn:RESET_PIN, cnt:19, img:1.0.0.0
Slinky 1.0.0.0
19:[ts=19000ssb, mod=6 level=4] rsn:RESET_PIN, cnt:20, img:1.0.0.0
Slinky 1.0.0.0

And from newtmgr:

➜  stm32f429 sudo newtmgr echo -c stm32f429 hello

➜  stm32f429 sudo newtmgr image -c stm32f429 list

I think this is running as it needs to be.


But when I setting slinky with REBOOT_LOG_FCB: 1, it will generate this
code in slinky-sysinit-app.c:

    /*** Stage 200 */
    /* 200.0: sys/reboot */
    log_reboot_pkg_init();

which cause error when running on STM32F429.

Not sure why reboot_init_handler will return MAGIC number (-7), and what
does reboot log doing.

Are there any documentation or help msg for this function?

Thanks,
Louie.
