SPI on mangOH Green


#1

Hi,

I have a few questions regarding SPI on mangOH.

  1. SPI2:
    Figure 2-13 on page 26 of the Developer’s Guide shows IoT#2 having a direct connection to SPI1. Is this true?
    I checked the schematic and it would seem that the SPI lines on IoT#2 are connected to pins 92, 93, 94, 95 on the CF3 socket, which are not dedicated SPI pins on the WP8548 module. Does SPI2 work? or is it intended to be used with different CF3 modules?

  2. SPI (in general)
    I’m trying to use SPI in user space (for the moment), but I cannot find the platform device at /dev/spidev_B_.C
    There’s /dev/sierra_spi but I get an error (Inappropriate ioctl for device) when trying to set the mode via ioctl.
    Is it instead mapped to some ‘tty#’ device?

Device: WP8548
Firmware: SWI9X15Y_07.11.09.00 r32989 CARMD-EV-FRMWR1 2016/08/11 18:03:20
Legato version: 16.07.0_cd4985660a55cc9a6f9a2ed28bcc757e_modified

Can anybody help me get the SPI device to show up in /dev/?
Are there any mangOH SPI examples I can follow? I couldn’t find one in the sample apps…a very short basic example on how to use each peripheral on the development platform would be most helpful.

Here’s my output after running modprobe -l if that helps

SPI API Legato Tutorial dead end?

Hi Raf,

For your questions:

SPI2:

I checked the schematic and it would seem that the SPI lines on IoT#2 are connected to pins 92, 93, 94, 95 on the CF3 socket, which are not dedicated SPI pins on the WP8548 module. Does SPI2 work? or is it intended to be used with different CF3 modules?

--> Yes, SPI2 is meant for different CF3 modules and is not supported on WP8548 module.

SPI (in general)
I'm trying to use SPI in user space (for the moment), but I cannot find the platform device at /dev/spidev_B_.C
There's /dev/sierra_spi but I get an error (Inappropriate ioctl for device) when trying to set the mode via ioctl.
Is it instead mapped to some 'tty#' device?


Can you try adding the following line of code in your user space code:
#ifdef SPI_IOC_MAGIC
#undef SPI_IOC_MAGIC
#define SPI_IOC_MAGIC 'l'
#endif

cheers,

Hi Ashish,

Thanks for your assistance.

I’ve added the code to my main application file (after the #include of spidev.h) and the error message has now changed to ‘Invalid argument’.

Is SPI_IOC_MAGIC a unique number used with sierra_spi?

close(8)

Here’s my code. It’s basically just the standard ‘spidev_test.c’ program with minor changes. Sorry for bloating this reply with it. I was unable to attach the files. It fails at setting the spi mode. Note that I’ve tried all 4 modes and each gives the same result - invalid argument.

Thanks again

#4

I don’t know if it matters, but you have a requires/device section in your adef file, but your adef also has sandboxed:false. It shouldn’t be necessary to map the device file into the sandbox if there is no sandbox.


#5

for mode set it as an int:
static int mode = SPI_MODE_0;

let me know how it goes. We plan to release an API for SPI functionality in the next 2-3 weeks.

cheers,
Ashish


#6

@dfrey Thanks for the tip - It makes sense.

@asyal That did it, Ashish! Loop-back tests are working now. Thanks again.
Great news. An API would be very handy. I look forward to its release.

Cheers,
Raf

Rafi,

We will release our SPI API mid next week. Look forward to feedback.

cheers,
Ashish


#8

Hi Ashish,

Just checking how the SPI API release is going and where might I be able to find it.

Cheers,
Raf


#9

Raf,
After internal discussions, we plan to integrate the SPI code in the next Legato release.
However, if you want , we can release it to you as an alpha user. This means that you are aware that it is not fully tested.
From our side, I would like to get feedback from you on the SPI APIs so we can improve it further.
Let me know if that is you are ok with this and we can provide the code to you.
cheers,
Ashish


#10

Ashish,
That works for me. I’d be happy to try it out and provide feedback.

Cheers,
Raf


#11

Hello Asyal,
I plan to work with SPI and I’m also waiting for the SPI APIs.
I’d like to help if it’s possible.

cheers,
Reunan


#12

Raf/Reunan,

You can get the SpiService and SpiTest from https://github.com/mangoh.
Note this beta code and will certainly change in the next few weeks.

cheers,
Ashish


#13

Ashish,

Thanks for providing the code.

I’m just having a little difficulty understanding what to do after after following the steps from https://github.com/mangOH/SpiService. Are you able to assist?

I have acquired the mangOH source code from the repository and made the necessary changes to both files.
Note that I’m using Developer Studio 4.1.1 and my installation did not have a ‘mangOH’ folder before.
How do I integrate the mangOH folder/files with DS? As far as I can tell, my current setup did not make use of the ‘targetDefs.mangoh’ and ‘mangoh.sdef’ files.

I could just clone both spi components and run them but would prefer to do it properly.

Cheers,
Raf


#14

Raf,
I built this using command line. Dev Studio integration will happen once this code is part of Legato main line (currently it is under review).
Why dont you use it using command line?
Ashish


#15

Hi Ashish,

Here’s what I get when trying to build from the command line:

legato@legato-VirtualBox:~/mangOH/apps/SpiService$ mkapp -v -t wp85 spiService.adef
Parsing file: ‘/home/legato/mangOH/apps/SpiService/spiService.adef’.

Application ‘spiService’ contains executable ‘spiService’.

** ERROR:
/home/legato/mangOH/apps/SpiService/spiServiceComponent/Component.cdef:5:8: error: Couldn’t find file ‘$MANGOH_ROOT/apps/SpiService/spi.api’.

I receive the same error when attempting to build ‘spiTest’.

The file it’s after is definitely there:
legato@legato-VirtualBox:~/mangOH/apps/SpiService$ ls
_build_spiService spi.api spiService.adef
README.md spiLibraryComponent spiServiceComponent

I’m thinking it’s caused by my environment being configured for DS, thus it’s not aware of mangoh.sdef, targetDefs.mangoh, nor $MANGOH_ROOT for that matter.

How can I reconfigure the legato environment to make this work?
Sorry if this is not the correct forum to be discussing this.

Thanks again,
Raf


#16

Can you change the path in cdef from: $MANGOH_ROOT/apps/SpiService/spi.api to: /home/legato/mangOH/apps/SpiService/spi.api


#17

Thanks Ashish - that did the trick.

There’s a bunch of cdef files from other services dependent on $MANGOH_ROOT so I just added these two lines to /home/legato/legato/packages/legato.sdk.latest/resources/configlegatoenv to make things easier.

sourceMangOHPath=/home/legato/mangOH/
export MANGOH_ROOT=${sourceMangOHPath}

All up and running now.

Raf


#18

Thanks for the update.
Cheers,
Ashish


#19

using Legato 16.10.1 you need to add
..le_spi -> spiService.le_spi
as binding in adef

and
le_spi.api

to requires api in Component.cdef

This is missing from the documentation and should be added for completeness.


#21

Hi everyone.
I am trying to enable SPI on my WP8548 and have some troubles with it
First of all i have legato 16.10on my target & i’m using this tutorial to enable SPI -> http://legato.io/legato-docs/latest/howToSPI.html I did all till step “Next, you’ll need to create a kernel module .ko file.” and went to -> http://legato.io/legato-docs/latest/yoctoOutofTreeKernelModule.html#howToAddKernelDriver_makeKernel there i did all till step “Build Kernel” and tryed to compile my spisvc.c module with “make” like in tutorial and it failed with error. Then i tryed to compile module with “sudo make” and it started to ask me about a hundred config questions, that i don’t even realize how to answer, and finaly it failed with error.
Can someone help me solving this issues? Or just say what am i doing wrong
Makefile
