Thank you very much. With these definitions i got a working SPI interface.

Hi,

CONFIG_SPI_($number) is set by the device tree in newer ncs versions, so you can remove this from the prj.conf.

Provided the zephyr tag that you're using, you're on a newer ncs version, which also uses pinctrl for allowing different sets of gpios for bus peripherals, which also requires different definitions as shown here:

https://github.com/nrfconnect/sdk-zephyr/blob/main/boards/arm/nrf5340dk_nrf5340/nrf5340_cpuapp_common-pinctrl.dtsi#L102-L117

and here:

https://github.com/nrfconnect/sdk-zephyr/blob/main/boards/arm/nrf5340dk_nrf5340/nrf5340_cpuapp_common.dts#L223-L229

Kind regards,

Håkon

Hi Hakon,

thank for the example.

When I try to build it, I get an error message: /prj.conf:9: warning: attempt to assign the value 'y' to the undefined symbol SPI_1

My experience with zephyr is very limited, so I am wondering if I made a mistake or the way zephyr is using the prj.conf during buildtime has changed during the last two years.

Here is what i have done: I extracted spi_test.zip to samples/basic/spi_test/ within my zephyr installation. Then I run west build -p auto -b nrf5340dk_nrf5340_cpuapp samples/basic/spi_test/

I use archlinux and my zephyr manifest git tag is “zephyr-v3.2.0-2474-g1aebcec02f”.

If I delete CONFIG_SPI_1=y in prj.conf, I am able to compile, but the SPI_1 device is not available so I get the “Could not get SPI_1 device” on my terminal.

To compile the main.c I have done some smaller changes:

add a zephyr/ in every #include <>
replace u8_t with uint8_t

This is the compile log.

HI Hakon,

just wanted to say thanks for this code! I have been struggling with the SPI for a while and this example explains it perfectly!!

Håkon Alseth — Wed, 28 Oct 2020 15:10:28 GMT

Has anything outside of the project changed since it was last opened up? If so, then you should always re-import the project to ensure that the underlying cmake configuration/output is correct.

Kind regards,

Håkon

Hi,

[quote user="Learner"]This does not make sense since I have admin rights on my machine. Plus, this problem is intermittent, one minute I don't have permission and the next I have full permission. It is frustrating and time consuming.[/quote]

If there's some program (notepad or similar) that has opened up one of the files in the build folder, windows will not allow you to delete the file.

Could this be the case here? There's a process keeping one of the files open?

[quote user="Learner"]I do try to delete the build folder, again it does not make sense, sometimes I can and at other times I am not allowed to delete the folder build/zephyr. I can delete its content but not the folder itself[/quote]

This sounds like a process is keeping the folder open. Its a generic problem on windows:

Has this type pf problems been reported by other users? I know a colleague of mine is having similar issues.

It would be greatly appreciated if you could help us come to the bottom of this and find the root cause. Because I know I will be facing the same problem soon.

Great!

Have you come across this problem before?

The log states that you have permission error:

Try deleting the build folder and re-import the project.

Hi Hakon,

Both SES v452c and v510d are behaving themselves now :), meaning I can open and build the project with this commented out line

#CONFIG_BOARD_ENABLE_CPUNET=n

However, I am having other problems with SES when sometimes, at random times, SES (v452c and v510d) cannot open a project that has not been changed for a while and was working fine before. If I keep trying few times it eventually works. See pictures and error log below.

Have you come across this problem before?

What am I doing wrong?

Could it be something to do with my laptop because I have not restarted it for over a week now?

Hi,

Do you still get the same issue if you move this board out of the boards/arm folder? If it is work-in-progress, it might be that the build system picks it up, especially if the names within the folder isn't changed.

Kind regards,

As I said in my previous post, SES v5.10d is very moody. Guess what? I can open and build the solution now. This is with the line CONFIG_BOARD_ENABLE_CPUNET=n enabled. However, when I commented it out I could not open the project. Below is the error log.

Hi,

[quote user="Learner"]I re-instated the line CONFIG_BOARD_ENABLE_CPUNET=n in prj.conf again in prj.conf but I still cannot reload the project. Below is the error.[/quote]

Could you click on "OK" and paste the full output from the build-window in SES? I can see that the failure is in line 35 of ZephyrConfig.cmake, but it would be good to see if there's anything interesting before that.

Hi Hakon,

I've re-downloaded the zip file and extracted ok.

I opened the project spi_example and built it ok.

I then commented out the line CONFIG_BOARD_ENABLE_CPUNET=n in prj.conf.

I tried to open the project but failed as with the old SES version.

I re-instated the line CONFIG_BOARD_ENABLE_CPUNET=n in prj.conf again in prj.conf but I still cannot reload the project. Below is the error.

This is very bizarre. SES seems to be very moody, one minute it is happy the next it is not.

Thank you for your help.

Have you checked if you have enough space available, etc?
