Hi

i update by cmd  "west init -m github.com/.../sdk-nrf --mr main"

a lot of project  that define self pin can not build,

because set pin by another psels

	i2s0_default_alt: i2s0_default_alt {
		group1 {
			psels = <NRF_PSEL(I2S_SCK_S, 0, 0X15)>,
					<NRF_PSEL(I2S_LRCK_S, 1, 0X08)>,
					<NRF_PSEL(I2S_SDOUT, 0, 0X13)>;
					// <NRF_PSEL(I2S_SDIN, 0, 0xFF)>;
		};
	};

android DeviceManage app DFU got ok,

ios phone sending time out.

even ios app i've remove and reinstll it.

Hi,

Please consider working with a stable release tag instead. Excerpt from the documentation regarding use of the main branch:

"The main branch of the sdk-nrf repository always contains the latest development state of the nRF Connect SDK. Since all development is done openly, you can use it if you are not particularly concerned about stability and want to track the latest changes that are being merged continuously into the different repositories." https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/dm_code_base.html#revisions

This is covered in the migration document here: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/migration/migration_guide_1.x_to_2.x.html#ncs-2-0-0-migration

In case the iphone may have stale bonding information stored for your peripheral, you may try to go tho the device list in settings->bluetooth and forget your peripheral device if it is listed, then turn Bluetooth off and on before you attempt DFU again.

Hi

thanks for reply,

i have reinstall 2.0.2.

nrf5340dk_nrf5340_cpuapp  i2s build.

(1) how to disable i2s SDIN pin?

it can't set to 0xFF,  no set means disable?

&pinctrl {
	spi3_default: spi3_default {
		phandle = < 0xa >;
		group1 {
			psels = <NRF_PSEL(SPIM_SCK, 0, 0x1f)>,
			<NRF_PSEL(SPIM_MISO, 1, 0x00)>,
			<NRF_PSEL(SPIM_MOSI, 1, 0x0d)>;
			// <NRF_PSEL(SPIS_CSN, 0, 0x0f)>;
		};
	};
	spi3_sleep: spi3_sleep {
		phandle = < 0xb >;
		group1 {
			psels = <NRF_PSEL(SPIM_SCK, 0, 0x1f)>,
			<NRF_PSEL(SPIM_MISO, 1, 0x00)>,
			<NRF_PSEL(SPIM_MOSI, 1, 0x0d)>;
			// <NRF_PSEL(SPIS_CSN, 0, 0x0f)>;
			low-power-enable;
		};
	};

	i2s0_default_alt: i2s0_default_alt {
		group1 {
			psels = <NRF_PSEL(I2S_SCK_S, 0, 0X19)>,
					<NRF_PSEL(I2S_LRCK_S, 1, 0X18)>,
					<NRF_PSEL(I2S_SDOUT, 0, 0X08)>,
					<NRF_PSEL(I2S_SDIN, 1, 0x07)>;
		};
	};
	
};
&spi3 {
    compatible = "nordic,nrf-spim";
    label = "SPI_3";
    status = "okay";
	cs-gpios = < &gpio0 0x10 0x1 >;
	pinctrl-0 = < &spi3_default >;
	pinctrl-1 = < &spi3_sleep >;
	pinctrl-names = "default", "sleep";
};

(2)  in NCS1.9.99- get i2s pin number from overlay note as follow line:

DT_PROP(DT_NODELABEL(i2s0), mck_pin)

how to get i2s pin number in NCS2.0.2?

(3) DeviceManage app DFU error "sending time out" on IOS,

but work well on Android. maybe Nordic should update IOS app.

tips: IOS phone had forget peripheral device , then close Bluetooth and restart,

and then restart phone, and then reinstall app.

                

Thanks  !

Best regards

Hi,

Sorry for the delayed response.

1) Setting the pin as unused is currently not supported through the pinctrl API. You will however achieve the same if you omit  i2s SDIN pin definition your devicetree like you suggested.

2) With pinctrl enabled you need to use the pinctrl_apply_state() to configure the i2s psel registers as shown here: https://github.com/nrfconnect/sdk-zephyr/blob/482dcc7865f7d3a458f061a1d8276c5801eed1e4/drivers/i2s/i2s_nrfx.c#L899 and init the driver with .nrfx_def_cfg.skip_gpio_cfg = true and .nrfx_def_cfg.skip_psel_cfg = true.

3) Did you test this with SDK v2.0.2?

Hi,

(1)about get pin number,

i want to get i2s pin number in source code,as follow line

int pin = NRF_DT_GPIOS_TO_PSEL(DT_NODELABEL(button0)

but don't konw how to get it in NCS2.0.2.

(2)about DFU time out,

yes, i test with SDK v2.0.2.

I said before, it work well in android, because 5340App only run DFU ota in main.

void main(void)

{

    printk("Hello World!\n" );

    ota();

}

when i add button enter DFU ota,

it show "time out" in android and IOS,

void main(void)

{

    printk("Hello World!\n" );

    init_button_led();

    while(true){

        if(will_ota) ota();

        else k_msleep(100);

    }

}

because DFU finshed and restart 5340 device,

phone app need connect 5340 device again,

if can't connect will show "time out", DFU failed.

     

i button again enter DFU when DFU finshed and restart 5340 device,

it will connect ok and show "complete",DFU success.

     

it means must bt_le_adv_start(...) for phone app connect  when DFU finshed and restart 5340 device.

why?  Is it the defect of NCS?

My app doesn't use Bluetooth, except for upgrading DFU.

bt_le_adv_start(...)  again means more complicated.

       

Best regards
