Setting up LVGL: fsl_cache.h not found

[TRNPep]

Hi everyone, i previously post a thread asking for help setting up the TFT_eSPI library to be able to use the LVGL library. I set it up correctly and now it is perfectly working. So I moved to the LVGL. After fallowing the simple steps for the set up that you can se here i tried to compile and load on my T4.1 the example LVGL_Arduino. Later i will download the lv_example library and try that one too. The problem is that it doesn't even compile because "fsl_cache.h" is not found on ...Documents\Arduino\libraries\lvgl\src\draw\nxp\p xp/lv_gpu_nxp_pxp.h . I took a look at lv_gpu_nxp_pxp.h and here's what I found:

#include "../../../lv_conf_internal.h"

#if LV_USE_GPU_NXP_PXP
#include "fsl_cache.h"
#include "fsl_pxp.h"

#include "../../../misc/lv_log.h"

So it includes fls_cache.h only if LV_USE_GPU_NXP_PXP is set. That is on User_setup.h, as you can see below.

/*Use NXP's PXP GPU iMX RTxxx platforms*/
#define LV_USE_GPU_NXP_PXP 1
#if LV_USE_GPU_NXP_PXP
    /*1: Add default bare metal and FreeRTOS interrupt handling routines for PXP (lv_gpu_nxp_pxp_osa.c)
    *   and call lv_gpu_nxp_pxp_init() automatically during lv_init(). Note that symbol SDK_OS_FREE_RTOS
    *   has to be defined in order to use FreeRTOS OSA, otherwise bare-metal implementation is selected.
    *0: lv_gpu_nxp_pxp_init() has to be called manually before lv_init()
    */
    #define LV_USE_GPU_NXP_PXP_AUTO_INIT 0
#endif

I'll be onest, i don't quite cach what it does (so big thank you if you can explain it to me), but seems to me that i can choose to set LV_USE_GPU_NXP_PXP or not. In fact, if I set it to 0, i don't get the fsl_cache.h error, but instead i get this:

Did you ever figure this out? I just got the exact same problem.

I played around with it for a bit and it doesn't look like there is going to be an easy fix. On the LVGL page I found the instructions for setting it up and they use the drivers from NXP's SDK. The big problem is that they appear to have a whole pile of dependencies from the SDK so you ca't just copy and paste in the drivers. I guess I will have to try out NXP's ide to get the PXP accelerated graphics to work.
