Hi biwa, I am assuming that you wish to get the BLE radio channel number used in the scan window as part of the advertisement report like in the lines of RSSI. But as this information is not part

Hi all, I'd like to amend the agenda for today's meeting with the following PRs which have been waiting for resolution for a while: - PR: Validate pin ordinals in wrapper functions -

Traditional locking in Zephyr is done with a single global "irq lock" (implemented on single processor systems with a straightforward interrupt mask). SMP allows for finer grained

There is a fix for exactly this race this in https://github.com/zephyrproject-rtos/zephyr/pull/21903 On 1/21/2020 1:49 AM, "曹子龙 wrote:

Hi, I think commit message gives an explanation https://github.com/zephyrproject-rtos/zephyr/commit/ec554f44d99eef8800e341db5fa95ba40755d351 Thanks, Pawel

HI folks: if from the call pass of z_swap, which with parameter, do_swap(key.key, lock, 1); because is_spinlock is 1, so the lock would be released before invoke the actual switch

Hi folks: why there are two implmentations of schedule? What is the difference "z_reschedule_irqlock" and "z_reschedule“? why two

Hi all, Tomorrow we will discuss an RFC that is ready to be merged, two items that were raised in last week's TSC and we will check on progress with the GPIO porting. - RFC (ready to merge): on-off

As I know, currently there is no support of SMP for ARM architecture in Zephyr

See the section on “CPU Mask” for directions on how to constrain threads to run on a particular set of CPUs. https://docs.zephyrproject.org/latest/reference/kernel/smp/smp.html

HI folks: Did the SMP support arm architecture boards presents? if yes, which one? Thank you! 曹子龙 珠海全志科技股份有限公司

Hi folks: throught the docment of zephyr smp imple. a task take the irq_lock can be yield to another thread, but would restore the spinlock own status when it comes back but, throught the code, i

Hi folks: Did the SMP impl. of zephyr support the cpu affinity settings? i have not seen the related members in k_thread structure. Thanks for your kindly

As a follow up we plan on The Jan 30th Dev Review meeting to discuss Pinmux/DT. - k

Hi, I suggest checking the stack sizes. CONFIG_NO_OPTIMIZATIONS is sometimes used to decide which size to apply. Stack overflow could cause strange issues. You can enlarge stacks enable stack analysis

Hi Chris and All, I replied too quickly. CONFIG_NO_OPTIMIZATIONS=y only delays the point at which the program hangs. In my case it starts by displaying data and BLE advertising as

Thanks Chris. That works. And using zephyr_cc_option(-O0) with CONFIG_NO_OPTIMIZATIONS=y does not cause any trouble. Still seems strange that other program do not seem to bother!
