Hi,

It seems like there could be some issues with your devicetree overlay. Can you share nrf52840dk_nrf52840.overlay?

Best regards,
Marte

Hi Marte, 
Thanks for fast support
Here is the overlay file :

/* STEP 2.1 - Add the SPI peripheral to spi1 */

&i2c0 { status = "disabled";};

&spi0 { status = "disabled";};

&i2c1 { status = "disabled";};

&spi1 {

status = "okay";

cs-gpios = <&gpio0 5 GPIO_ACTIVE_LOW>;

ili9341@0 {

compatible = "ilitek,ili9341";

reg = <0>;

spi-max-frequency = <8000000>;

reset-gpios = <&gpio0 6 GPIO_ACTIVE_LOW>;

dc-gpios = <&gpio0 7 GPIO_ACTIVE_LOW>;

width = <240>;

height = <320>;

rotation = <0>;

backlight-gpios = <&gpio0 8 GPIO_ACTIVE_HIGH>;

gamset = [00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 10 11 12 13>;

};

};

Hi,

There is an error with the gamset property. The ">" at the end must be replaced with "]":

gamset = [00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 10 11 12 13];

Please note that the pins you are using are, by default, used by the interface MCU UART and NFC on the nRF52840 DK. I recommend using pins that are not used by other peripherals. You can see which pins are used in the nRF52840 DK - connector interface.

If you still get build errors after fixing the gamset property and pins, please upload your project so I can reproduce it.

Best regards,
Marte

unfortunately, the same issue still present.
I wanna upload the project as you recommended.
