Hard fault

[stetzanton]

Hey. Trying to run the gif library on stm32f407. I get hardfault after launch. I get "invalid signature" in the console. But the process continues to run after that.

It seems there is no proper error handling in the lib.

"Invalid signature" means the GIF file was invalid.

I've added error handling here: https://github.com/lvgl/lv_lib_gif/commit/d64a40001fe01e35e01533b8deee942756943617

[stetzanton]

can you send any correct gif file for test?

[kisvegabor]

it works for me:

[stetzanton]

Hardfault is passed. But "invalid signature" is in place. I use your gif file placed in the root of SD-card. I also have a problem reading images from the card. All UI elements are created successfully. But the images are not loading. Maybe this is a common problem?

[kisvegabor]

How do you set the path of the files? Do you use LVGL's files system API? E.g. S/path/to/image.gif

[stetzanton]

"S:/path/to/image.gif" But images with errors in .bin format Problem with cache start after include lv_lib_gif and replace lvgl version (feat/new-fs-api) and lv_fs_if(new-api)

[kisvegabor]

You don't need to convert it into bin, just use the gif as it is.

[stetzanton]

I do not convert .GIF to .bin. The cache issue was with old files that were loaded from SD card(background pictures). Images from flash(button icons) are loaded and displayed normally.

[kisvegabor]

I suggest using a simulator (I use Eclipse you can use other) to have a common platform to investigate the issue.

If you place the images to the projet's root folder and you enable LV_FS_IF_PC 'P' it should work for "normal images":

lv_img_set_src(img, "P/my_image.bin");

Is it working?

[stetzanton]

.bin working good with master-branch of lvgl can i use lv_lib_gif with master branch or only with new-fs-api?

[stetzanton]

When i use without lv_fs_if library have this errors http://joxi.ru/n2Ybe6hbDObbA6 (with master branch of lvgl .bin files are open good with "S:/path/to/image.bin"). Where i can add disk letter for new-fs-api branch of lvgl?

[kisvegabor]

can i use lv_lib_gif with master branch or only with new-fs-api?

No, I made some changes in the FS API when added the GIF library.

When i use without lv_fs_if library have this errors http://joxi.ru/n2Ybe6hbDObbA6 (with master branch of lvgl .bin files are open good with "S:/path/to/image.bin"). Where i can add disk letter for new-fs-api branch of lvgl?

If you don't use lv_fs_if you need to register a driver yourself. See here https://docs.lvgl.io/latest/en/html/overview/file-system.html
