- arm: cortex_r: config_userspace: nested interrupt level is not decremented following syscall
Re: arm: cortex_r: config_userspace: nested interrupt level is not decremented following syscall
- In v2.3 when building with CONFIG_USERSPACE enabled, I see that we do not do a context switch a short time after POR. I've chased this back and found the the cpus.nested has incremented
to 6, so the code in z_arm_int_exit() thinks we are in a nested interrupt, and does not switch to another task.
Hi Phil, can you open a GH issue on this? Stephanos or maybe Ioannis may want to take a look at it.
Also, what platform do you use to test user mode on cortex-R? qemu_cortex_r5 doesn't work with it (gaps in emulation support for the MPU perhaps?)
