Network forum agenda

Jukka Rissanen
 

Hi all,

There is a network forum meeting today 4 Aug at 8AM PDT / 17.00 CET.

Agenda:

- Making the new TCP stack the default. See
https://github.com/zephyrproject-rtos/zephyr/pull/27208 for details.

- Network stack testing. Maxwell Pro license just expired, any
volunteers to start using it. Discussion how to do network testing in
the future.

If you have anything else you want to discuss, please let me know.

Re: Adding support for Nordic PDM Driver in Devicetree #pdm #driver #nrf52832

Hi Martí

Thank you for your detailed answer! This was a great help
You're welcome!





Strictly speaking, actual drivers -- as in drivers/subsystem/my_driver.c
files -- are enabled using Kconfig, not devicetree. So
CONFIG_MY_DRIVER=y in Kconfig means "enable my driver," which means
something like "compile my_driver.c."


I think I get it now. The dts must specify whether or not the PDM hardware is available on the given board, and if so, what pins etc.
The Kconfig are used to enable the driver to use for the application,
and the CMakeLists includes the correct sources, based on whether the
implementation should be either nrfx or some other implementation.
Correct.





config MY_AUDIO_DRIVER
bool
default $(dt_compat_enabled,$(DT_COMPAT_NORDIC_NRF_PDM))
help
Enable my audio driver.

It looks like someone already prepared the setup for a PDM driver, since the SOC Kconfig defines a HAS_HW_NRF_PDM, which means I could depend on that?
I tried something like this:

config PDM_NRFX
bool "nRF PDM nrfx driver"
default y
depends on HAS_HW_NRF_PDM
select NRFX_PDM
help
Enable support for nrfx Hardware PDM driver for nRF52 MCU series.

Totally based off of the PWM Kconfig, but it should work right?
Those HAS_HW_NRF_* options are slated for removal at some point:

https://github.com/zephyrproject-rtos/zephyr/issues/8481

It would be better not to add more uses of them, especially if this work
is going upstream.





It looks like there is already a dts/bindings/audio/nordic,nrf-pdm.yaml
file, though, so it doesn't seem like you need to define your own
binding. I didn't find any drivers for it in the upstream tree, though.

I took a look at the pwm_nrfx driver, which seems to act as a sort of wrapper for the nrfx_pwm driver in the Nordic HAL module.
I assume that I would have to do something similar, as there already
is a pdm driver in the Nordic HAL module?
That is the "shim driver" approach, yes. It's a perfectly valid way of
doing things in Zephyr.

This way I would take an already implemented PDM driver for Nordic chipsets (such as the nRF52832 on the Nordic Thingy 52), and incorporate it into the Zephyr system, and making it hardware agnostic.
The remaining thing to do, is then modify the devicetree for the Nordic devices that actually have PDM hardware, so that the driver can be used for these boards.

Again, I'm working this stuff out as I go, and this is the method I found so far, but I think it makes sense.
I would love to hear your (or anyone else with some knowledge on this)
input, to make sure I'm on the right path.
At least the nRF5340 and nRF9160 SoC DTSI files have pdm nodes defined.
If you need to add them for other SoCs, the existing definitions may be
a good starting point.

Hi there. I'm porting Zephyr to the Arduino Nano 33 IOT. The board has
a
LSM6DS3 IMU which is very similar to the LSM6DSL that's already supported
by Zephyr and I'd like to re-use it.

I've refactored [1] the lsm6dsl driver to be multi-instance. What's the
best way of then using the same driver for two different compats? The
best
I've come up with is [2] but that has name collision issues.
Have you tried to set some state in the config structure based on the
value of DT_NODE_HAS_COMPAT(DT_DRV_INST(your_instance_number),
some_compat)?
That sounds good.

The second part of the problem is iterating over both the lsm6dsl and
lsm6ds3 types. Doing two DT_INST_FOREACH_STATUS_OKAY(fn), one for each
compat, can give name collisions. Any ideas?
Could you please describe the collisions in more detail? I checked the
patch in your footnote [2] below but I'm not seeing the issue, sorry.

Taking a guess, though, if there's an issue with naming a global
variable for a device config or data field within the "fn" expansion,
perhaps pasting DT_DRV_COMPAT onto the relevant variable names using the
## preprocessor operator is a fix?

Thanks,
Martí

Note that the chips also have a different WHO_AM_I value, so need very
slightly different configuration.
E.g. setting the WHO_AM_I in your config struct based on this, and using
that in your init functions to disambiguate.

Dear Maureen and Jrosenth,

Thank you very much for your kind help. I am using the latest version of Zephyr (as shown in bold in the following code) and also I downloaded the micropython in the Zephyr Project Folder from "git clone https://github.com/micropython/micropython.git". Now I want to run a blink led example to test the Micropython functionality by using the example given in the link "https://github.com/micropython/micropython/tree/master/ports/zephyr". When I run the "make" command I am getting the following error as shown at the end of the following code. Please note I am using nrf52840 dk. Request to please advise.

You could try porting MicroPython to run on Zephyr if it meets your needs. Note that you're looking at a minimum of ~150KB of extra flash space usage, depending on architecture, which features you enable, etc.

Latest Progress....[Zephyr-devel] Python Interpreter for Zephyr

Muhammad Muh <muhammad.muh83@...>
 

Dear Maureen and Jrosenth,

Thank you very much for your kind help. I am using the latest version of Zephyr (as shown in bold in the following code) and also I downloaded the micropython in the Zephyr Project Folder from "git clone https://github.com/micropython/micropython.git". Now I want to run a blink led example to test the Micropython functionality by using the example given in the link "https://github.com/micropython/micropython/tree/master/ports/zephyr". When I run the "make" command I am getting the following error as shown at the end of the following code. Please note I am using nrf52840 dk. Request to please advise.

Hi Carles,

is it possible to include this import whitelist in the official kernel documentation?

This seems to work fine for me locally:

Hi,

For our projects, we are trying to minimise the components we need to check out and download so reduce disk space, bandwidth and automated build times. The default zephyr westyml pulls in a lot of repositories we don’t need and there is the import name whitelist feature which can be used which is what we’re looking for, however it seems that according to https://docs.zephyrproject.org/latest/guides/west/manifest.html#west-manifest-ex3-1 a whitelist overrides a blacklist. For our projects, we are using the Nordic nRF connect SDK which makes use of the name whitelist feature and the nRF connect SDK repository pulls in the zephyr component – is there a way to further limit this from our project? This is from the west.yml file in that repository:

        name-whitelist:

          - canopennode

          - ci-tools

          - cmsis

          - civetweb

          - edtt

          - fatfs

          - hal_nordic

          - hal_st

          - libmetal

          - littlefs

          - loramac-node

          - lvgl

          - mbedtls

          - mipi-sys-t

          - net-tools

          - nrf_hw_models

          - open-amp

          - openthread

          - segger

          - tinycbor

          - tinycrypt

 

So for example we don’t want canopennode so is there a way we can exclude it from our west.yml file which is above the nrf repository which will then be passed down to the zephyr manifest file through the nrf manifest file, whilst overriding the nrf whitelist (our west.yml > nrf west.yml > zephyr west.yml)?

Thanks,

Jamie

You could try porting MicroPython to run on Zephyr if it meets your needs. Note that you're looking at a minimum of ~150KB of extra flash space usage, depending on architecture, which features you enable, etc.

Re: Adding support for Nordic PDM Driver in Devicetree #pdm #driver #nrf52832

Frederik David Damsgaard Popp
 
Edited

Hi Martí

Thank you for your detailed answer! This was a great help

First of all, I won't claim to be an audio expert, so this is purely based on what I have learned the past couple of weeks.
I'm not an audio expert, but are you sure the existing audio codec API
is not right?

As far as I could work out, the audio codec API is purely output, so that won't work for a microphone.
The other option was the dmic driver, which utilizes PDM hardware, but converts it into PCM for the Application, so that won't work either.

Strictly speaking, actual drivers -- as in drivers/subsystem/my_driver.c
files -- are enabled using Kconfig, not devicetree. So
CONFIG_MY_DRIVER=y in Kconfig means "enable my driver," which means
something like "compile my_driver.c."

I think I get it now. The dts must specify whether or not the PDM hardware is available on the given board, and if so, what pins etc.
The Kconfig are used to enable the driver to use for the application, and the CMakeLists includes the correct sources, based on whether the implementation should be either nrfx or some other implementation.

config MY_AUDIO_DRIVER
bool
default $(dt_compat_enabled,$(DT_COMPAT_NORDIC_NRF_PDM))
help
Enable my audio driver.

It looks like someone already prepared the setup for a PDM driver, since the SOC Kconfig defines a HAS_HW_NRF_PDM, which means I could depend on that?
I tried something like this:

config PDM_NRFX
bool "nRF PDM nrfx driver"
default y
depends on HAS_HW_NRF_PDM
        select NRFX_PDM
        help
           Enable support for nrfx Hardware PDM driver for nRF52 MCU series.

Totally based off of the PWM Kconfig, but it should work right?

 

It looks like there is already a dts/bindings/audio/nordic,nrf-pdm.yaml
file, though, so it doesn't seem like you need to define your own
binding. I didn't find any drivers for it in the upstream tree, though.

I took a look at the pwm_nrfx driver, which seems to act as a sort of wrapper for the nrfx_pwm driver in the Nordic HAL module.
I assume that I would have to do something similar, as there already is a pdm driver in the Nordic HAL module?
This way I would take an already implemented PDM driver for Nordic chipsets (such as the nRF52832 on the Nordic Thingy 52), and incorporate it into the Zephyr system.
The remaining thing to do, is then modify the devicetree for the Nordic devices that actually have PDM hardware, so that the driver can be used for these boards.

Again, I'm working this stuff out as I go, and this is the method I found so far, but I think it makes sense.
I would love to hear your (or anyone else with some knowledge on this) input, to make sure I'm on the right path.

Best
