Dear Mr Jan,

Thank you very much for your help. The problem is resolved until the program Building. Now when I west flash, it runs but I am not getting any output on the screen.  I am using the following Ada Fruit version.

Hi Muhammad,

For the nrf52840_pca10056 you need to specify a display shield that supports ili9340, eg. west build -b nrf52840_pca10056 -- -DSHIELD=adafruit_2_8_tft_touch_v2

Note that ili9340 sample has been removed in the latest master as there is now a common sample that support different kind of display shields.

Dear All,

I hope you all are doing well.

I am trying an example in

zephyrproject/zephyr/sample/display/ili9340

The example is building fine with nucleo board

west build -b nucleo_l476rg .

BUT

Please advise on the following error when building with nrf52840 west build -b nrf52840_pca10056 .
