CPU frequency and RISC-V boards
Peter Kietzmann
Dear community,
how is the CPU frequency configured in zephyr? I found `clock-frequency` configurations for `cpu0` in different device tree source files. This is missing for hifive1_revb or rv32m1_vega_zero_riscy, however, hifive1_revb defines `clock-frequency = <16000000>` (16 MHz) in multiple peripheral structures. Is this the CPU frequency? The platform is supposed to run with up to 320 MHz, though. More specifically, I would like to run both platforms with maximum speed. How can I achieve that? I'd be happy about any advice :). Cheers Peter

Until recently there was an open draft PR adding support for the CM4 core within the RV32M1: https://github.com/zephyrproject-rtos/zephyr/pull/27497 Unfortunately it was closed due to inactivity. Regards, Brix -- Henrik Brix Andersen

Cortex support for OpenISA VEGAboard?
Peter Kietzmann
Dear community,
is there support for operating the OpenISA VEGAboard with the Cortex M4F or Cortex M0+ processors? If yes, can someone point me to the development procedure? If no, is anyone working on that? Cheers Peter

In general, that's left as an exercise for the user, as far as I know.

Hi Mohamed,
i think #include <drivers/sensor.h> with standard #include <zephyr.h> etc should work.

Re: zephyr API to read the nRF5340 die temperature

Hi,
try this, I hope it will work #define TEMP_SENSOR_NAME "TEMP_0"
int valid = 0;
const struct device *tempSensor
device_get_binding(TEMP_SENSOR_NAME);
sensor_value sensor_val;
int rc =
sensor_sample_fetch(tempSensor);
if (rc == 0) {
rc = sensor_channel_get(tempSensor, SENSOR_CHAN_DIE_TEMP,&sensor_val); }else{ valid=0; } if (rc == 0) { double temp = sensor_val.val1 + sensor_val.val2/1000000.0; //printk("Temp: %d.%d\n", sensor_val.val1, sensor_val.val2/10000); valid=1; }else{ valid=0; } you also need to enable
CONFIG_SENSOR=y
CONFIG_TEMP_NRF5=y in prj.conf

Hi,
I would recommend looking at samples\bluetooth\peripheral_ht\src I managed to create my code for
nrf52832 based on that sample. If you have problems with that
sample, I can paste some code here.

zephyr API to read the nRF5340 die temperature
#nrf5340
Mohamed Belaroussi
Hello, I am looking for some some nRF5340 example code that reads the nRF5340 die temperature using zephyr APIs. I've looked at previous posts but I could only find this one https://devzone.nordicsemi.com/f/nordic-q-a/56171/how-to-get-die-temperature-on-nrf52832-using-zephyr from 10 months ago that stated none existed. Thank you. Kind regards

How to Use the generic Zephyr SPI driver API without creating a full-blown zephyr-based driver
#driver
Mohamed Belaroussi
Hello, I need to communicate with an SPI device (Semtech LR1110) connected to the nordic SoC nRF5340 via its SPI peripheral. I have the driver source code but I am not sure about the steps I need to take to integrate the driver code into zephyr. I know that I have to create a device tree overlay file that defines the compatibilty compatible="nordic,nrf-spim" and specifies the MISO, MOSI, SCK and CS pins etc... &spi1 { I am not sure whether I need the following section because I do not want to create a full-blown driver in the zephyr device tree. What else do you suggest instead? adxl362@0 { }; I've read in one of the posts the following: Drivers-wise, you essentially have two options (zephyr choice is divided into two options): 1. Use the generic Zephyr driver API a. Hard way: Create a full-blown zephyr based driver - this is normally not done unless you plan to do a pull-request to the zephyr-rtos project. b. Easier way: Setup the SPI instance in your application, then add the communication protocol on-top. 2. Use the nordic specific nrfx driver directly You can use the Zephyr API to create your own driver. This includes creating Kconfig menu, device tree, and developing the sensor src and porting to use the spi.h API. This would then be a portable driver, which can theoretically run on any of the supported SPI "backends" (ie: x86, arm, xtensa, etc), but its not a straight forward process. You also have the option to use the nrfx_spim driver directly in your application, by adding CONFIG_NRFX_SPIM=y, then adding for instance CONFIG_NRFX_SPIM1=y. It looks like option 1b is the best way but I need more details, a step-by-step guide if possible would be greatly appreciated. Thank you. Kind regards Mohamed

Re: Adding an out of tree driver
Bolivar, Marti
Hi,
toggle quoted messageShow quoted text
You should just need to add it to the build system's Kconfig and CMakeLists.txt hierarchy like any other file in your module. There are worked examples in https://github.com/nrfconnect/sdk-nrf/tree/master/drivers. HTH, Martí "Lawrence King via lists.zephyrproject.org" <lawrence.king=irdeto.com@...> writes:

Adding an out of tree driver
Adding an out of tree board is easy, I just set the variable BOARD_ROOT and the build system happily finds my_custom_board. This is nicely described by following the links from here: https://docs.zephyrproject.org/latest/application/index.html#boards
Now I want to do the same for my_custom_sensor_driver. Is there a variable I can set (like SENSOR_ROOT) that will find my out of tree sensor driver? Unfortunately the documentation at https://docs.zephyrproject.org/2.3.0/samples/application_development/out_of_tree_driver/README.html is a little sparse.
How do I include an out of tree sensor driver?
