Enabling SD Card in asset_tracker V1

Hello again!

Could you try to disable the UART0 on the nRF9160? It's enabled by default and uses pin 28 as "rx-pin". It should be enough to the code below to the nrf9160dk_nrf9160.overlay file.

&uart0 {
	status = "disabled";
};

Best regards,
Carl Richard

Hi Carl,

I am still having a battle with this board I'm afraid.

Still trying to toggle pin 0.28 from the nRF91 device

I have done the overlay for the nRF52 - seems to make no difference

So I cut the SB13 pad, disconnecting it from the mux:

now it only links directly to the nRF91 part

Using the following code:

struct device *dev;
dev = device_get_binding("GPIO_0");
gpio_pin_configure(dev, 28, GPIO_OUTPUT); 
gpio_pin_set(dev, 28, 1);

I cannot change the state of this pin in any way

Is there something else?

Thanks

Billy

Hello!

Yes, that looks about correct! The project running on the nRF52840 can be anything really, but I think hello_world or something simple is good enough.

Looking at it like this I realize that the process is quite tedious, but alas, it's what works.

Best regards,
Carl Richard

Good morning!

Great, so to confirm the process I need to:

1) "Open nRF Connect SDK project" and select nrf9160dk_nrf52840 project

2) Create an overlay in the folder called nrf9160dk_nrf52840.overlay disabling vcom2_pins_routing

3) Save and close solution

4) "Open nRF Connect SDK project" and select nrf9160dk_nrf52840 project, with clean build option ticked

5) Change the program switch position on the DK to nrf52840

6) Build and flash the project

7) Job done

Is that about correct?

Thanks again

Billy

Good morning, Billy!

That's good to hear! You can route the pins of the DK using a device tree overlay. More details can be found in the nRF9160 DK - nRF52840 firmware documentation.

In this case I believe you can add the following to "nrf9160dk_nrf52840.overlay":

&vcom2_pins_routing {
        status = "disabled";
};

Hi Carl,

SDCard is now working, and it was the DBG_CMD pin causing the issues, as you mentioned it was already being used.

I need to free up all the analog ports, so i have the following

I am not using the nRF52

If i force the logic level of the analog switch being driven by nRF52 P1.12 to a 0, can you confirm that i would then be able to use these for pins within the nRF91 as i wish? or will i need to also configure the SDK in some way?

Thanks

Oh my, that is looking better! I would have never stumbled on that

I need now to modify my hardware so i can use the new pins, what would be better is if i could use the origional pins.

I need P0.13 to P0.20 for 8 channels ADC, seems i cannot change these pins

I also need to free up some other pins, I dont need any VCOM ports, and im not using the nrf52 at all, also dont really need the external memory.

How could i change the project to free up some of these pins?

Thanks for your continued support

Hi again!

No, you must reopen the project itself. Press "File"->"Open nRF Connect SDK project" and find your project. Then check "Clean Build Folder" and then "Ok".

Hi,

I pressed Clean Solution, then exit and reopen IDE - is this enough?

RE: Enabling SD Card in asset_tracker V1

Carl Richard — Mon, 19 Apr 2021 09:43:40 GMT

Hello!

Good to hear. Menuconfig is unfortunately unaware of the log level Kconfigs as they are generated.

I should have mentioned this earlier: when changing the overlay you must reopen the project with a "Clean Build Folder" for the changes to take place. Did you do this?

Best regards,
Carl Richard

billywalton — Mon, 19 Apr 2021 09:22:09 GMT

Hi Carl, thanks for your reply

Yes i am using the nRF9160DK

adding CONFIG_DISK_LOG_LEVEL_DBG=y to prj.conf works - thanks, so menuconfig is not the way

Changing the overlay to

&spi3 {
        status = "okay";
        cs-gpios = <&gpio0 13 GPIO_ACTIVE_LOW>;
        sck-pin = <11>;
	mosi-pin = <12>;
	miso-pin = <10>;

        sdhc0: sdhc@0 {
                compatible = "zephyr,mmc-spi-slot";
                reg = <0>;
                status = "okay";
                label = "SDHC0";
                spi-max-frequency = <24000000>;
        };
};

Using 10, 11, 12 and 13 does not help, in fact now not even the CS or CLK lines are working, i get no output from any of the pins

Could it be the overlay is not being included?

Hi again, Billy!

Thank you for your patience. Do I understand it correctly that you are using the nRF9160DK? In that case, some GPIO pins have already dedicated functions and should not be used for other means. There is an overview of these on in the infocenter documentation. From this I see that you have been using the pins that are dedicated to the interface MCU and DK board control. Could you try another set of pins instead, for example P0.10, P0.11, P0.12 and P0.13?

How did you try to enable the debug log in prj.conf? It should be enough to add CONFIG_DISK_LOG_LEVEL_DBG=y.

Best regards,
Carl Richard

Hi again,

Some additional information.

I am not sure where the configuration is now supposed to happen, using the menuconfig option or directly in the prj.conf file.

I tried using the menuconfig to enable log debug for the SDHC driver, but was not successful, the option seems to be ignored, if i manually add

#define LOG_LEVEL LOG_LEVEL_DBG

to disk_access_spi_sdhc.c then i get the following output

>> ff ff ff ff ff ff ff ff ff ff[00:00:00.205,627] [0m<dbg> sdhc_spi.sdhc_spi_tx_cmd: cmd0 payload=0[0m

So i would certainly expect activity on the MOSI pin, some kind of other configuration must be stopping this somewhere.

Thanks for your help

Billy

Hi Carl,

It seems to be something to do with the SPI config as if I move the MISO and MOSI to other pins, the same problem is apparent, I never see any activity on them, I have just moved them to 0.23 and 0.24, removed the SDCARD and just watched the lines.

CLK works,

CS works

nothing on MOSI

I'm pretty sure the init routine should be sending a string of 0xff's via MOSI on startup.

What could I have missed to stop the signals?

Hi Carl,

I'm still struggling with this....

I have the following overlay:

&spi3 {
        status = "okay";
        cs-gpios = <&gpio0 25 GPIO_ACTIVE_LOW>;
        sck-pin = <21>;
		mosi-pin = <27>;
		miso-pin = <22>;

        sdhc0: sdhc@0 {
                compatible = "zephyr,mmc-spi-slot";
                reg = <0>;
                status = "okay";
                label = "SDHC0";
                spi-max-frequency = <24000000>;
        };
};

Prj.conf

#SDHC
CONFIG_DISK_ACCESS=y
CONFIG_LOG=y
CONFIG_FILE_SYSTEM=y
CONFIG_FAT_FILESYSTEM_ELM=y
CONFIG_PRINTK=y

# SPI
CONFIG_DISK_ACCESS_SDHC=y
CONFIG_DISK_ACCESS_SPI_SDHC=y
CONFIG_SPI=y
CONFIG_SPI_3=y
CONFIG_SPI_NRFX_RAM_BUFFER_SIZE=8
CONFIG_MAIN_STACK_SIZE=4096

# Segger RTT
CONFIG_USE_SEGGER_RTT=y
CONFIG_RTT_CONSOLE=y
CONFIG_UART_CONSOLE=n
CONFIG_LOG_BACKEND_RTT=y
CONFIG_LOG_BACKEND_UART=n

when i run the code I get

*** Booting Zephyr OS build v2.4.99-ncs1  ***

On the scope, I see the CS and CLK lines moving, but nothing on the MISO or MOSI (I am running the board in 3V mode)

Could there be something else in the asset_tracker app that is causing a problem for me?

RE: Enabling SD Card in asset_tracker V1

Hi again!

The asset tracker does not have an overlay file and this must be added. For the nRF9160DK you can create a new file called "nrf9160dk_nrf9160ns.overlay" and add your desired configurations there. This will be included automatically next time you build the application (make sure to reopen the project in SES). Please notify me if you face any issues with this!

Best regards,
Carl Richard

Hi Carl,

In the asset tracker folder, I have copied across the settings from the example in the link you sent to prj.conf

But where is the overlay file? or does the asset_tracker not have one?

The asset_tracker files:

I was imagining I could copy the data from the example overlay file into the asset_tracker overlay file and change the pin numbers appropriately
