sys_reboot(SYS_REBOOT_COLD) not working if CONFIG_SPM=n

[Andrea]

If I set CONFIG_SPM=y I can flash merged.hex and successfully call sys_reboot(SYS_REBOOT_COLD) to reboot the system.

If I set CONFIG_SPM=n (and build/flash the SPM project separately), the call to sys_reboot(SYS_REBOOT_COLD) doesn't cause a reboot. It just hangs.

How can I reboot the system from a project having CONFIG_SPM=n?

Hi,

I assume you are on v1.0.0 tag. In the CONFIG_SPM=y project, the libspmsecureentries.a is linked in , and the sys_reboot()/sys_arch_reboot() is overridden to call spm_request_system_reboot() instead. Looks it's not beeing linked in when CONFIG_SPM=n. I assume you then are stuck here.

A workaround could be to set tz_nonsecure_system_reset_req_block(0); , see this link
