Re: Zephyr's k_sleep gets stuck on nRF52832
Peter A. Bigot
Version 1.14.99 suggests you have a snapshot of the development series leading up to the recent 2.0 release. The problem you're reporting was fixed in #17845 in upstream Zephyr 2019-08-01. It may be worth updating to the 2.0 release for your development as many other problems were fixed in the latter part of August.

Zephyr's k_sleep gets stuck on nRF52832
Kimberly Langland <KimL@...>
Hello All,
We were seeing an issue that occasionally, all tasks waiting for a timeout using k_sleep get stuck in the suspended state (while other tasks continue to run normally), and then after about 8 minutes full normal functionality returns.
After digging into this issue, is appears that either the RTC needs an N+3 buffer between the RTC->COUNTER and the RTC->CC value to guarantee to trigger the ISR (instead of an N+2 buffer as documented), or that there is a race condition in the nrf_rtc_timer driver where between the time of reading the RTC->COUNTER, and writing to RTC->CC, RTC->COUNTER has already advanced.
Has anyone else seen this, or know the appropriate fix/workaround?
Detailed description: * Zephyr Version: 1.14.99 * Running on nR53832
Each time this behavior occurs, the first task in the timeout_list (in the kernel/timeout module) has a timeout time of 1 tick. Reading the RTC1 registers, directly as this occurs, the RTC1->COUNTER value is just above the RCT1->CC[0] value. Normal behavior returns about 8 mins later when the RTC1->COUNTER register passes the RTC1->CC[0] value a second time (this is a 24 bit register clocked at 32kHZ with no prescaler).
In Nordic's documentation for the RTC on nRF52832 it states: "If the COUNTER is N, writing N+2 to a CC register is guaranteed to trigger a COMPARE event at N+2". Zephyrs driver seems to address this case by writing N+2 to the RTC1->CC[0] register (instead on N+1) in the case that a one tick timeout is requested. However in this case we are still not receiving the ISR until the COUNTER has looped around.
I have tried setting the RTC1->CC[0] register instead to N+3 (in the 1 tick timeout case), and have not yet seen the issue reoccur with the following modification to the nrf_rtc_timer driver.
/* dt - is the delta between RTC->COUNTER and RTC->CC[0] * cyc - is the value to write to RTC->CC[0] */ } else if (dt == 1) { - set_comparator(cyc + 1); + set_comparator(cyc + 2); }

Listen for "USB_DETECTED" events?
Benjamin Lindqvist
Hi, Going through the APIs today looking for a public function for discerning if we are connected to something (i.e. we are supplied by VBUS) but I couldn't find anything. There is some internal API at `subsys/usb/usb_device.c` (usb_register_status_callback) but it clearly won't work since it's not public etc. Am I just missing it or does it not exist?

Re: c++ application development
#nrf52840
Peter A. Bigot
Not until we get #19002 and then #18464 merged. Since I'm the one with concerns about those I'll work to get them in next week if that's possible. For now you could make progress by taking 18464 into your Zephyr tree; then you can use the malloc-based new/delete that comes free from combining libc++ and newlib.

Hi, Is there source for memory allocation using new other than k_malloc ? Because in my application want to use memory alloation from free heap not from the heap memory pool.

Dynamic memory allocation is supported in Zephyr C++, though you have to enable a source for the memory. You should not have to define overloads for those operators.
tests/application_development/libcxx in current master is the most complete example of C++ use. PRs 18464, 18991, and 19002 may be helpful as well. Peter

c++ application development
#nrf52840
Narendar Malepu
Hi,
we are developing an application in c++, for dynamic memory allocation using new as operator overloading as below void *operator new(size_t size) {
void *p = malloc(size);
return p;
}
void operator delete(void *ptr)
{
free(ptr);
} but as per documentation it is mention that new and delete are not supported, complier is not showing any error or warning for my usage. Can you help regarding above new operator overloading whether to use it or not in my application. Thanks

To address a potential follow-up, I am looking into adding betterSounds great, and even the test file you referred to is 20K, so testing coverage is definitely not "bare".

RTIO API, Other potential uses
Tom Burdick
Hi Everyone, I've been steadily and surely working on a new API, primarily aimed at sensors, but has been split in such a way that device drivers could extend the base API of configuring a stream with rules and triggering reads for other things. It was always my intention that this base API potentially be useful for other things. Things like sensors that might also need DMA like transfers without actually copying things. A look-see of how things are coming along, for sensors and this API, can be found Note that the rtio_sensor prefix and requirements are an extension of the RTIO device API rtio_sensor_api: https://github.com/bfrog/zephyr/pull/1/files#diff-7de7f52cfc39aed90f28eab7c0ebb97fR235 I'd be interested in knowing if anyone has a potential use case for the base rtio_api besides the sensor use that I'm working on. If so I'll push hard to work on that with you to get it in for 2.1 perhaps. Let me know your thoughts! Cheers, Tom

Re: Dual ethernet interfaces on Zephyr OS ?
Jukka Rissanen
Hi,
toggle quoted messageShow quoted text
there exists NET_DEVICE_INIT_INSTANCE() macro (in include/net/net_if.h) that can be used for this purpose. You would need to edit the ethernet driver and call that macro with suitable parameters. You could also create ETH_NET_DEVICE_INIT_INSTANCE() (it does not exists yet) from ETH_NET_DEVICE_INIT() (in include/net/ethernet.h) and add instance support to that. Cheers, Jukka

Miguel Wisintainer <tcpipchip@...>
Sir,
Can you help me ? I tried to implement the ADC on that chip but now success!
Can you send a simple example that enable a analog input (for example 10 bits, and intern 3.3V reference) and read it ?
P0.04 AIN5 Digital I/O Analog input General purpose I/O pin. ADC
Today i implemented the BLE and works very fine! The board used was BLE400! But i want to send the analog value!
Thank you so much!
