ESP-IDF 6.0.1 unable to compike/build project useinf fatfs.

lvgl 9.5
There is a bug in the fatfs code that causes a compile error at line 268 in lv_fs_fatfs.c

Code: Select all

    do {
        res = f_readdir(dir_p, &fno);
        if(res != FR_OK) return LV_FS_RES_UNKNOWN;

        if(fno.fname[0] == 0) break; /* End of the directory */

        if(fno.fattrib & AM_DIR) {
            lv_snprintf(fn, fn_len, "/%s", fno.fname);
        }
        else lv_strlcpy(fn, fno.fname, fn_len);

    } while(lv_strcmp(fn, "/.") == 0 || lv_strcmp(fn, "/..") == 0);

    return LV_FS_RES_OK;
}

If i fix the problem ninja detects a checksum fail and spits the dummy:

Code: Select all

Bootloader binary size 0x5dc0 bytes. 0x240 bytes (2%) free.
[7/9] Linking CXX executable Test_fatfs.elf
FAILED: Test_fatfs.elf 

No matter what I try I can't get round the problem. Sorry about the typos in the header, it's getting late in the day.

Hi, sorry for the delayed response.

This seems like an error in the LVGL library, not ESP-IDF itself.

I would recommend switching to the POSIX FS driver and using ESP-IDFs vfs and fatfs support, if at all possible.
