NUCLEO-GFX01M2 Initialization error

[jasonlee3]

I'm running the following git source on the NUCLEO-G071RB with NUCLEO-GFX01M2.

GitHub - lvgl/lv_port_stm_nucleo_g071rb: LVGL ported to ST's NUCLEO G071RB board

But, I got an error at the cursor location from the attached figure (LCD Error 1.png).

The return value of "data" from st7789v_recv_data function was all 0.

I'm not sure this is correct. I guess there should be some values in it.

When I run the X-Cube-Display sample program, I got the same error.

Please let me know what cause this kind of error.

Hello @jasonlee3 ,

I'm not sure if you are planning on using graphics on your board or not, but I suggest using TouchGFX instead of your current project. 
TouchGFX has already a Board Setup which contains all the required settings for NUCLEO-G071RB + GFX01M2; You just need to develop your GUI and the rest in handled by TouchGFX.

I hope this helps you, don't hesitate to ask more questions
