This is a functioning sample
I need to add CONFIG_MPU=y to prj.conf and grant access for user thread to the gpio "port" object
I tried to grant gpio.port before, but without CONFIG_MPU=y... resulting in hardfault
Then i add CONFIG_MPU=y but grant access to gpio object... resulting in permission error
Finally I tried with both and boom
Anyway i need to use CONFIG_NO_OPTIMIZATIONS=y to debug step by step inside the syscalls...

if I remove the k_object_access_grant(&dbg_pin1, usermode_thread); the program goes in
static inline int z_vrfy_gpio_port_toggle_bits(const struct device port, gpio_port_pins_t pins)
{
K_OOPS(K_SYSCALL_DRIVER_GPIO(port, port_toggle_bits)); <--
and finally in
/ LCOV_EXCL_START /
FUNC_NORETURN __weak void arch_system_halt(unsigned int reason)
{
ARG_UNUSED(reason);
/ TODO: What's the best way to totally halt the system if SMP
* is enabled?
/
(void)arch_irq_lock();
for (;;) {
/ Spin endlessly */
}
}
with reason == 3

Anyway I read that in usermode threads can use syscalls... And gpio api should be syscalls... 😵💫

I can.
In my opinion i need to place the gpio descriptor in a memory section that have user access and/or give the user access to the memory area in which the gpio registers are mapped... But i am new in user space and searching for a guidance...
