Hi Muhammad,

Looks like you made a typo in the build command it should be something like:
west build -b nrf52840_pca10056 samples/drivers/display -- -DSHIELD=adafruit_2_8_tft_touch_v2

Hi Muhammad,

Could you switch to latest master and test with samples/drivers/display, for me that sample is working with the same adafruit display?
Keep in mind that in case you have a preview development kit of the nrf52840_pca10056 you will need an extra patch:

Dear Mr Jan,

Thank you very much for your help. The problem is resolved until the program Building. Now when I west flash, it runs but I am not getting any output on the screen.  I am using the following Ada Fruit version.

Hi Muhammad,

For the nrf52840_pca10056 you need to specify a display shield that supports ili9340, eg. west build -b nrf52840_pca10056 -- -DSHIELD=adafruit_2_8_tft_touch_v2

Note that ili9340 sample has been removed in the latest master as there is now a common sample that support different kind of display shields.

Jan

Dear All,

I hope you all are doing well.

I am trying an example in
zephyrproject/zephyr/sample/display/ili9340

The example is building fine with nucleo board
west build -b nucleo_l476rg .

BUT

Please advise on the following error when building with nrf52840 west build -b nrf52840_pca10056 .

Hi all,

Due to the switch to summer time in the US, the meeting today is at 17h CET/8AM PDT, so in 15min.

Subject: [Zephyr-devel] API meeting next week: Focusing on watchdogs

Hi all,

Next week (Tuesday 10th of March) we will focus our attention to
watchdog handling in Zephyr.

We recently closed #22858 with the merge of #22859, but this was a
temporary solution to what is ultimately a wider problem that requires
a discussion regarding the way Zephyr manages watchdogs in general.

A good description of the current issues with the
CONFIG_WDT_DISABLE_AT_BOOT option can be found in #22858.

During the call we will discuss the approach we want to take and
document it in #23282, which I just created today.

Zephyr 2.2 released

Johan Hedberg
 

Hi,

We are excited to announce the release of Zephyr RTOS version 2.2.0!

Major enhancements with this release include (but are not limited to):

* We added initial support for 64-bit ARMv8-A architecture (Experimental).
* CANopen protocol support through 3rd party CANopenNode stack
* LoRa support was added through integration of the Semtech LoRaWAN endpoint
stack and addition of a new SX1276 LoRa modem driver.

The detailed release notes can be found here:

https://github.com/zephyrproject-rtos/zephyr/releases/tag/zephyr-v2.2.0

I would like to thank the community members who contributed to this release. There were a total of 2642 commits from 205 contributors in the development of 2.2. It has taken a lot of hard work from everyone in the Zephyr community!

Starting now, the tree is open for new features targeting the 2.3 release, which is tentatively scheduled for May 29th 2020.

Thanks again,

Johan

Hi Muhammad,

Looks like you made a typo in the build command it should be something like:

Hi Muhammad,

Could you switch to latest master and test with samples/drivers/display, for me that sample is working with the same adafruit display?
Keep in mind that in case you have a preview development kit of the nrf52840_pca10056 you will need an extra patch:

Hi Muhammad,

For the nrf52840_pca10056 you need to specify a display shield that supports ili9340, eg. west build -b nrf52840_pca10056 -- -DSHIELD=adafruit_2_8_tft_touch_v2

Note that ili9340 sample has been removed in the latest master as there is now a common sample that support different kind of display shields.

Hi Muhammad,

Could you switch to latest master and test with samples/drivers/display, for me that sample is working with the same adafruit display?
Keep in mind that in case you have a preview development kit of the nrf52840_pca10056 you will need an extra patch:

Hi Muhammad,

For the nrf52840_pca10056 you need to specify a display shield that supports ili9340, eg. west build -b nrf52840_pca10056 -- -DSHIELD=adafruit_2_8_tft_touch_v2

Note that ili9340 sample has been removed in the latest master as there is now a common sample that support different kind of display shields.

Re: Updating a board file in zephyr for all releases

Hi Jamie,

 

It is unlikely that we will release 2.0.x or 2.1.x releases in the short term, so my suggestion is that you send one PR to the 1.14 branch and another one to master.

 

Regards,

 

Carles

Hi,

I noticed an issue in a board file at the weekend whereby it doesn’t reboot the module after flashing it, it’s a quick fix and I can submit a PR but wanted to know how to deal with applying it for all versions of zephyr. Since there’s the 1.14 branch, 2.0 branch, 2.1 branch and master – do I submit one PR per branch? Or just one for e.g. 1.14 and it gets propagated through?
Thanks,
Jamie

Initial build errors

Thomas Törnblom
 

I'm just starting up my IAR porting effort again and thought I would just build a simple out of the box project with the standard tools, but I'm immediately running into issues.

I'm on Ubuntu 18.04.4 LTS and have followed https://docs.zephyrproject.org/latest/getting_started/index.html

Hi Vinayak,

Thank you for the support.
I have created the GH issue for the same https://github.com/zephyrproject-rtos/zephyr/issues/23319

Thanks,

Hi  Mayank,

 

When you create the GitHub issue please be specific about the exact layout of the setup you have.

It is not fully clear to me if you are connecting the nrf52840_pca10056 to the i.MX6UL via the PCA10056’s USB connector (i.e. using the PCA’s on-board debugger) or directly via lines to the UART from the i.MX’s pins to the nRF52840’s pins without any circuitry.

 

Thanks,

 

Carles

Hi All,

Here i'm facing the issue even after using the full UART (Tx, Rx, RTS, CTS).
These 4 pins are connected & configured from both (i.MX6UL & nrf52840_pca10056).

Note : nrf52840 chip is flashed with HCI_UART sample app of zephyr. In that i have configured 4 pins and make HWFC enable from nrf5.conf file.

Ans still i'm not facing this issue continuously. Lets say i'm keeping beacon scanning on for 4-5 hours then its working fine. It crashes when i keep it running for 2-3 days.

Thanks,
Mayank

Ok,

 

Please create  a GH issue and mentioned as much details as possible to help me reproduce the issue.
