boards/arduino-mkrzero: add initial support #6881

aabadie · 2017-04-10T07:57:00Z

And factorize code with arduino-mkr1000 since these boards are very similar.
The Arduino MKRZERO uses the second SPI to connect a SD card device, I configured it to use the one available in RIOT. This is not yet tested though.

I also noticed that there's a third one in the family: Arduino MKRFOX1200 that offers a SigFox compatible antenna.

aabadie · 2017-04-10T07:57:29Z

And this PR is based on ~~#6666~~

aabadie · 2017-05-16T10:29:32Z

since #6666 has been merged, I rebased this one. Tested mkr1000, still works.

boards/arduino-mkrzero/include/board.h

+ * @name    SD Card device configuration
+ * @{
+ */
+#define SDCARD_SPI_PARAM_SPI         (SPI_DEV(1))


This is the part, I'm not totally sure of. @haukepetersen or @vincent-d any comments?

Depends on what the question is... Does the arduino-mkrzero come with an on-board SD-card slot? If yes, then this looks valid to me (as long as the SD-card slot is connected to the pins mapped for SPI_DEV(1)...).

It should be ok, regarding the specs. I just don't know what CD1 is on the SD card reader.

Could be "card detect"?

Thanks, googling points toward this direction. I added a define for this pin below in the file.

haukepetersen · 2017-05-16T15:35:44Z

before merging this PR, I would however like to see a better solution for the bossa tool, as having the 4th board shipped with the same binary tool is ugly and bad -> so I would like to have a better solution before we go on. Sounds fair?

aabadie · 2017-05-16T16:02:16Z

Sounds fair?

Yes, I'm interested in looking into this except if you feel very motivated.

haukepetersen · 2017-05-17T10:06:34Z

done: #7068

+        .miso_mux = GPIO_MUX_D,
+        .mosi_mux = GPIO_MUX_D,
+        .clk_mux  = GPIO_MUX_D,


I noticed my silly mistake while testing WINC1500 WiFi module. 🤕 Could you please change the MUX pads to:

.miso_mux = GPIO_MUX_C, .mosi_mux = GPIO_MUX_C, .clk_mux = GPIO_MUX_C,

Thank you.

no problem, directly squashed and pushed

+    {
+        .dev      = &SERCOM2->SPI,

This pin definition for the second SPI is different from mkr1000. I'll have to provide the SPI configuration for each boards.

haukepetersen · 2017-05-23T07:36:10Z

now that #7068 is merged, would you mind to rebase and make use of it?

aabadie · 2017-05-23T07:53:26Z

would you mind to rebase and make use of it?

I'm on it

aabadie · 2017-07-17T10:12:48Z

@astralien3000, I pushed a fix regarding the PWM: pin ~2 and ~3 are working but I couldn't find the correct conf for pin ~4 and ~5. So there's only 2 available PWM pins in the default configuration.

Regarding the periph_timer test, I didn't test but it should work as I didn't change it and is working (normally) with mkr1000.

aabadie · 2017-08-21T12:18:34Z

@astralien3000, if you have some time can you give another try to this one ?

astralien3000 · 2017-08-21T14:54:34Z

periph_pwm OK (for ~2 and ~3)
periph_timer still blocking

aabadie · 2017-08-22T07:54:35Z

@astralien3000, thanks for testing again.

Regarding the timer test issue, I fixed it: by default mkrzero use the sdcard_spi module which itself uses xtimer and for some reason this messes up this test (TIMER_0 being initialized with different values apparently).
The fix is simply to remove the dependency to sdcard_spi which makes sense since this is up to the user to include it or not.

In the mean time, I also fixed the second spi periph configuration which was wrong.

Directly squashed and rebased.

Can you test again ?

astralien3000 · 2017-08-22T08:41:32Z

Yes ! Now it works !

aabadie · 2017-08-22T08:55:44Z

@haukepetersen, this one is ready now (and tested). Would be great if you could approve it (and merge ;)) !

aabadie · 2017-08-22T14:51:04Z

@haukepetersen ?
