Many thanks Rod.

Things have moved on a lot but this was very helpful in getting me unstuck.

With a bit of help from Simon this is now sorted out.

Hi Paul,

I have not looked at this for a while so I can't say 100% that this code is correct, but I have shared it anyway. Let me know if it works and if not, I will do a bit more digging my end.

Hi Rod,

I'm travelling the same route on nrfConnect SDK 1.4

Like you I got my I2C version working first and then wanted to use SPI.

Any chance you could share your working sample?

I have also posted this https://devzone.nordicsemi.com/f/nordic-q-a/70393/nrf9160-dk-spi-from-bme280-sensor-config-issue - no answer on that so far.

Thx.

Hi,

I managed to get it working !

Thanks,

Rod

RE: Basic SPI reads and writes

Øyvind — Fri, 24 May 2019 08:29:09 GMT

Ok. Just to get back on the right track again:

Are you able to run the SPI example without BME280? What problems are you seeing?
Is the hard fault issue still there?
- In prj.conf, you must add:
```
CONFIG_MAIN_STACK_SIZE=4096
```

Kind regards,
Øyvind

Yes, it solved the SPM issue, but Im now back to the problem of trying to get SPI to work!

Hi Øyvind,

I got this working but not 100% sure what actually did the trick. Based on this thread "

nRF9160 at_client sample project"

i deleted my path and env variables.

I then ran this again..

pip3 install -r zephyr/scripts/requirements.txt
pip3 install -r nrf/scripts/requirements.txt
pip3 install -r mcuboot/scripts/requirements.txt

as well as the update as above. Something did the trick and it burst into life.

So, I can no generate a merged.hex file and my code complies and runs. Unfortunately, my basic SPI reads and writes still dont work but at least I am now running on SPM

Hi Rod,

Really sorry for this being so difficult to fix, I have not seen similar issues.

[quote user="RodWatt"]2. I tried a complete new install. But as you will see from below, I still get the "West already initialised" error[/quote]

You need to find a folder named .west on your computer. This folder is generated when initializing west. Try to find this folder and delete it to see if this has any impact.

I am discussing the issue in my team and will get back to you asap.

Kind regards,
Øyvind

Hi Øyvind,

Ok, I have gone though your steps as above.

1. I deleted CmakeCache.txt and ran zephyr-env.sh. When I tried to build, I get the same error as above.

2. I tried a complete new install. But as you will see from below, I still get the "West already initialised" error

Watts-MacBook-Pro:zephyrproject Watt$ mkdir NCS2
Watts-MacBook-Pro:zephyrproject Watt$ cd NCS2
Watts-MacBook-Pro:NCS2 Watt$ west init -m https://github.com/NordicPlayground/fw-nrfconnect-nrf --mr v0.4.0
West already initialized. Aborting.

3. I don't think its my code, to prove this I tried to build at_client. I get the same error

So, I think i need to carry out a complete reinstall but it won't seem to let me do this simply my creating a new NCS2 directory.

How can I do a clean install?

RE: Basic SPI reads and writes

Øyvind — Wed, 22 May 2019 08:39:33 GMT

Hi Rod,

This is not making any sense. There is clearly an issue with your NCS install, but I am not fully able to reproduce the issue. There seems to be an issue with your path, from what I was able to reproduce.

Please follow the next steps. They will be divided into 3 sections, each tackling in a different way.

The first thing to try, if you were able to update the nrf repo and run west update:

In your application: /Users/Watt/Documents/Switch_That/Nordic_Semi_Code/SPI_Test do you have a CmakeCache.txt? (Not the one in the build folder)

If so, please delete this and the build folder. Then to ensure the correct path, please run:

Run NCS/Zephyr/zephyr-env.sh

Then try to make a new build folder and run:

cmake -GNinja -DBOARD=nrf9160_pca10090ns ..

The second thing to try, as you are getting "West already initialized. Aborting.":

The clean install needs to be in a completely new folder. Please make a new folder with a completely new name e.g. NCS2, etc.

mkdir NCS2 && cd NCS2
west init -m https://github.com/NordicPlayground/fw-nrfconnect-nrf --mr v0.4.0
west update

To ensure the correct path, run:

NCS2/Zephyr/zephyr-env.sh

Then try to program NCS2\nrf\samples\nrf9160\at_client, without changing the code to ensure everything works that way.

The third thing is that you send me your project so that I can test it here.

If anything is unclear, let me know.

Kind regards,
Øyvind

Hi Øyvind,

Ok, I will try this later when I have some time, although I think I may have done this previously, I will go through the steps as you have detailed just to check. If this doesn't work, I will carry out clean install. What's the easiest way of doing a complete clean install from a command line?

RE: Basic SPI reads and writes

Øyvind — Tue, 21 May 2019 08:08:19 GMT

OK, there is something missing here.

Please do the following:

cd ncs/nrf
git checkout master
git pull

Now verify that you have the correct tag:

git tag

Outputs:
v0.1.0
v0.1.0-rc1
v0.3.0
v0.3.0-rc1
v0.3.0-rc2
v0.4.0
v0.4.0-rc1
v0.4.0-rc2

From the output, we see that tag v0.4.0 is available. We can now check out this tag:

git checkout v0.4.0

Outputs:
Note: checking out 'v0.4.0'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

  git checkout -b <new-branch-name>

HEAD is now at f925102 manifest: Updated manifest to use D4 release tags.

Then we can update using west:

west update

This should fix the issues you have seen, building SPM and the sample project in one. Can't remember if I wrote this before, but SES v4.16 does not support debugging a multi-image .hex file i.e. merged.hex. You have to program it manually. The workaround is explained here. We are working on a fix.

Ok, I have updated NCS as above and build my code using

west build -b nrf9160_pca10090ns -d build
west flash -d build

I was expecting this to create a merged hex file but is only seems to create the hex for my application.

I can confirm this by looking at the memory map.

What am I missing here?

Please read "Updating the repositories".

Your NCS folder should be similar to this:

ncs
 |___ .west
 |___ mcuboot
 |___ nrf
 |___ nrfxlib
 |___ zephyr

Enter the following in command line:

cd ncs/nrf
git checkout v0.4.0
west update

[quote user="RodWatt"]You say I need to set the zephyr environment first, is this necessary? This should be set already?[/quote]

If you have added this path to your environmental variables, then ignore that message.

Hi Øyvind,

Sorry, I just want to check I her the latest tools. Im running everyone from a command line

So, to update to the latest version of NCS, is it just this....

cd ncs
git fetch ncs
west update

You say I need to set the zephyr environment first, is this necessary? This should be set already?

Hi Rod,

[quote][/quote]

Please can you clarify the steps to build my test program, with SPM merged and flash my board. Is it as simple as the code below?

Using the latest version of NCS, (v0.4.0), just remember to set zephyr environment first. After that, you should be able to run these commands and program your board.
Edit: See more information here.

Kind regards,
Øyvind

Hi Jan,

Just wanted to nudge you on this again :-) I have now written a simple SPI program which I wish to test. When I run this, I am reading zeros back. However, I am still using "secure_boot" and have not yet migrated to "spm". I am hoping that a move to SPM will help.

Please can you clarify the steps to build my test program, with SPM merged and flash my board. Is it as simple as the code below?

west build -b nrf9160_pca10090ns -d build
west flash -d build

Thanks,
Rod

Hi Jan,

So just to clarify the update process, (sorry for this, I just want to check I'm not missing any steps.)

cd ncs
git fetch ncs
west update

I am then building my application and flashing as follows

cmake -GNinja -DBOARD=nrf9160_pca10090ns ..
ninja flash

Regards,

Rod

Hi Rod,

If you are on the latest NCS master ("git fetch ncs" and checkout ncs/master or rebase your branch on top of it, then "west update"), SPM will automatically be included when you compile for nrf9160_pca10090ns. It will be compiled and merged with your application, so that when you run "west flash" to program the DK, both SPM and application are programmed together. You don't need to compile and program secure_boot/SPM separately. By default SPI3 instance is then set as non-secure and you should be good to go.

Let us know how it goes.

Regards,

Jan Tore

Hi Jan,

Thanks for your reply. I will add the cs-gpios... code as above in my overlay file and see if that helps.

I have updated my code base using the following

cd ncs/nrf
git checkout c1939d963fe2c18013ffb8de0bd8f6fc1d91724d
git checkout -b <choose_branch_name>
west update

Previously, Øyvind suggested I replace the secure boot code with the new SPM. You will see above that I have tried to install and build this but I keep getting errors.

Could you have a look at the errors above please and let me know if you see what Im doing wrong

Thanks,

Rod
