lodepng: decoder_open: error 83: memory allocation failed

[mtojek]

LVGL version

v9.2.0, v9.3.0

What happened?

Hey!

I'm having a hard time figuring out how should I modify lv_conf.h to display PNG file using lodepng:

[Error] (7.180, +8)      lv_draw_image_normal_helper: Failed to open image lv_draw_image.c:174
[Warn]  (7.242, +62)     decoder_open: error 83: memory allocation failed

I want to run the code on ESP32-S3 (Lolin32). I was able to easily display PNG images with v8.3.2, but API in v9 changed, and I can't determine which #define values should I use.

How to reproduce?

I'm experimenting with:

// LVGL memory
#define LV_MEM_CUSTOM 1
// #define LV_MEM_SIZE (128U * 1024U)
#define LV_MEM_CUSTOM_INCLUDE <esp32-hal-psram.h>
#define LV_MEM_CUSTOM_ALLOC(size) ps_malloc
#define LV_MEM_CUSTOM_FREE(ptr) ps_free

and:

#define LV_MEM_SIZE (96 * 1024U)
#define LV_MEM_POOL_INCLUDE <esp32-hal-psram.h>
#define LV_MEM_POOL_ALLOC ps_malloc

So is the goal to change to new allocators? If so, you can select LV_STDLIB_CUSTOM here and create a new file similar to this.

Actually I think we should have a ready to use config for ESP.

Closing in lack of feedback.
