mtd_mapper problem

[Laczen]

Description

I am trying to work with mtd_mapper. As a test I have changed the filesystem example (first lines in main) as:

#if defined(MTD_0) && \
   (defined(MODULE_SPIFFS) || defined(MODULE_LITTLEFS) || \
    defined(MODULE_LITTLEFS2) || defined(MODULE_FATFS_VFS))
    /* spiffs and littlefs need a mtd pointer
     * by default the whole memory is used */
    mtd_mapper_parent_t parent = MTD_PARENT_INIT(MTD_0);
 
    mtd_mapper_region_t region = {
        .mtd = {
            .driver = &mtd_mapper_driver,
            .sector_count = MTD_0->sector_count,
            .pages_per_sector = MTD_0->pages_per_sector,
            .page_size = MTD_0->page_size,
        },
        .parent = &parent,
        .sector = 0,
    };

    fs_desc.dev = MTD_0;
    fs_desc.dev = &region.mtd;

#endif

(I switch the two last lines to go from MTD_0 to mtd_mapper).

When I compile and test this for MTD_0 the sample works, if I use the mtd_mapper the sample gets in a read-loop (reading the first page of the MTD_0). I am working on a esp8266.

As I am quite new to riot, is the mtd_mapper definition correct ? If so, how can I avoid it going into a read-loop ?

After doing some further research I found that this is fixed by (#17866).
