Board support for nrf54l15 QFN40 (QDAA), CSP47 (CAAA) and QFN52 (QGAA)

[Gujju]

Hi,

I am developing on nRF54L15 chip by using Insight ISP2454-LX variant, and while creating new board for it, I am unable to find package variants other than OFN48 (QFAA). 

And by continuing with QFN48 board, I am getting error as I am trying to use P1.15 pin which is available in QFN52 but not in QFAA.

So, how to solve this issue?

And I also tried following this method mentioned in the devzone and encounter some error

NCS 3.0.2 Create new board wizard missing nRF54L05/10 - Nordic Q&A - Nordic DevZone - Nordic DevZone

Hi Shivam, 
I will check internally, could you show me the error log when you try to assign something to P1.15 ? 

[Gujju]

Hi Hung,


Here are the error logs when I try to assign P1.15

Hi Hung,


I tried the suggested part on the DK and surprisingly, it works.

main.c

#include <zephyr/kernel.h>
#include <zephyr/device.h>
#include <zephyr/devicetree.h>
#include <zephyr/drivers/gpio.h>
#include <zephyr/sys/printk.h>

/* Node label from the overlay: user_input: user-input { ... } */
#define USER_INPUT_NODE DT_NODELABEL(user_input)

static const struct gpio_dt_spec user_input =
	GPIO_DT_SPEC_GET(USER_INPUT_NODE, gpios);

int main(void)
{
	int ret;

	if (!device_is_ready(user_input.port)) {
		printk("GPIO device not ready\n");
		return -1;
	}

	/* Configure as input; pull-up comes from DT flags */
	ret = gpio_pin_configure_dt(&user_input, GPIO_INPUT);
	if (ret < 0) {
		printk("Failed to configure pin: %d\n", ret);
		return -1;
	}

	while (1) {
		int val = gpio_pin_get_dt(&user_input);
		if (val < 0) {
			printk("Read error: %d\n", val);
		} else {
			printk("P1.15 level = %d\n", val);
		}
		k_msleep(500);
	}
}

.overlay

/ {
    user_input: user-input {
        compatible = "nordic,gpio-pins";
        /* Port 1, pin 15, pull-up, active high */
        gpios = <&gpio1 15 (GPIO_PULL_UP | GPIO_ACTIVE_HIGH)>;
        status = "okay";
    };
};

&gpio1 {
    status = "okay";
};

&gpiote20 {
    status = "okay";
};

But when I flashed the same working firmware on custom board, it crashes.

So, is there a way or workaround to work with P1.15 pin. And any updates related to having other variant support?

And also, when I flashed the custom board firmware on DK, it gives me same error that I am having in custom board.

Hi Shivam, 
I suspect that it has something to do with the QFN52 variant as it's not reproducible on the DK here as well. 
Could you try to put a breakpoint inside nrf_gpio_pin_present_check() function inside nrf_gopio.h and step there to see where/why exactly it crashes ? 

I just want to double check, could you confirm that the exact hex file you flashed on the DK worked fine, but it crash on your board with nrf_gpio_pin_present_check() issue in the log as you shown earlier ? I need to know if they use the same hex and behave differently.

PS: Please test with latest SDK v3.2.1

 Hi Hung,

The pin is working fine.

It was an internal error; I had improper registers shifting.

Thank you for helping out.

Have a good day.

[Hung Bui]

Hi Shivam,

Thanks for letting us know. Have a nice day!
