Configuring Levelx

I am kind of lost about filex vs levelx configuration.

My memory is the w25q64jv, it has 8mb being 2048 blocks of 4096 bytes.

Configuring levelx:

    nor_flash->lx_nor_flash_total_blocks               = 2048;
    nor_flash->lx_nor_flash_words_per_block            = 128;

What I have understood is Levelx uses 1 sector (512b) for control, so 7 sectors are left for data for each block (4096b).

Now I computed the total data sectors available: 7 x 2048 = 14336 and have used this amount when formating the media (total_sectors).

Is that right?

    Looks like this "community" is not much alive. Few questions, some views, really no answers.

    Anyway, the configuration I stated before is working in the hope it can be of any help to the "viewers"

    I have upgraded to levelx 6.3.0, for it states to have improved performance.

    For the usage I am doing, after a lot of benchmark tests, and if I understood it right, I followed the "The FileX NOR flash format should be one full block size of sectors less than the NOR flash provides"  tip in "NOR FileX Integration" of https://learn.microsoft.com/en-us/azure/rtos/levelx/chapter5, and let it be even after no difference was felt.

    Maybe some configuration can be adjusted yet, because the performance really degrades badly as memory is filled. The time, or maybe some help for our colleagues, will tell.
