Custom Board Issues with zypher project in SES

Try changing the compatible to "lcd16x2-pins" (same as in the yaml file), so the overlay file looks like this:

/{
    aliases {
        lcd0 = &lcd0;
    };

    lcd16x2 {
        compatible = "lcd16x2-pins";
        status = "okay";
        lcd0: lcd_0{
            lcdgpios = <&gpio1 10 GPIO_ACTIVE_HIGH>;
            label = "LCD_D1";
            status = "okay";
        };
    };
};

When I did that, and tested with this code:

#define LCD_PIN0_NODE DT_ALIAS(lcd0)
static struct gpio_dt_spec lcd_pin0 = GPIO_DT_SPEC_GET_OR(LCD_PIN0_NODE, lcdgpios, {0});
.
.
.
void main(void)
{
    printk("lcd_pin0.port: %p\n",(void*)lcd_pin0.port);
    printk("lcd_pin0.pin: %d\n", lcd_pin0.pin);
    .
    .

It worked fine, I got this output:

*** Booting Zephyr OS build v2.6.99-ncs1-1  ***
lcd_pin0.port: 0x4b20
lcd_pin0.pin: 10

Dear, the yaml file is in attdevzone.nordicsemi.com/.../1805.lcd16x2_2D00_pins.yaml.txt

I could not find the .yaml file for the compatible "lcd_pins" in <ncs location>\zephyr\dts\bindings\, so I assume you have added it yourself. If so, could you upload that file, so I can test this on my side.

Dear Simon, after copying the custom board to nrc/... directory, the Build is successful. When, Debug is run, and rach to the custom Pins initialization, the custom pins do not have any address assgigned. Pls, see the image.

Hi Simon, I shall try to keep custom board in project folder and revert to you with result ..thanks

See my comment earlier and check out the sample https://github.com/nrfconnect/sdk-zephyr/tree/v2.6.99-ncs1-1/samples/application_development/out_of_tree_board

provide the custom path of the board folder by using this line: https://github.com/nrfconnect/sdk-zephyr/blob/v2.6.99-ncs1-1/samples/application_development/out_of_tree_board/CMakeLists.txt#L6. If you put the board folder in your project, you need to set it to ${CMAKE_CURRENT_LIST_DIR}.

Dear Simon, I also copied the my custom board to nrc/........ The CMake and Buil Solution now run successfully. But, is it mondatory to keep custom board in default directory of nrc ? If, a custom path of board is to be provided, how can that be done ? please, test at your end and then guide me .

Thanks

I did the following:

Updated NCS to v1.7.1
Copied the board folder bms_nrf5340 into /ncs/zephyr/boards/arm
Copied the bms sample into /ncs/zephyr/samples
Built the bms sample with the bms board:
- west build -b bms_nrf5340_cpuapp -d build_test

It worked fine:

simon@simon-HP-Pavilion-Laptop-14-bf1xx:~/ncs/zephyr/samples/bms$ west build -b bms_nrf5340_cpuapp -d build_1234

I'm using Linux and have not SES installed, but I don't see why the approach above shouldn't work on SES as well.

Try the approach above. Delete the build folder before building again and make sure to place the board folder inside /ncs/zephyr/boards/arm

If it still doesn't work for you I will install SES and try to get it working there.

By the way, if you want to place the board inside the project, check out the sample /ncs/zephyr/samples/application_development/out_of_tree_board to see how to go about it.

Best regards,

Simon

Dear Simon, I followed the procedure suggested by you to change board name. The custom name of my project is bms. When, project is created nRF Connect SDK , I selected my custom project and manually added the board from same directory. The bms project folder is in attachement. I am using nRF V1.71. The error as shown in attached is shown an project is not created.

I tried to create a custom board from the nRF5340 DK in NCS v1.8.0

I used the case sensitive find and replace functionality in vs code to do the following:

Replace all instances of "NRF5340DK" with "CUSTOM"
Replace all instances of "nrf5340dk" with "custom"
Replace all instances of "nRF5340 DK" with "Custom"

Then I modifed all the file names by replacing "nrf5340dk" with custom.

Evenutally I tested the sample ncs/zephyr/samples/hello_world (NCS v1.8.0) and it worked like expected:

*** Booting Zephyr OS build v2.7.0-ncs1-1-g0dce71e2a469  ***
Hello World! custom_nrf5340_cpuapp

Here is the generated board folder. Can you test it on your side with NCS v1.8.0 and see if it works?
