How to prevent assert failed: lfs_bd_prog lfs.c:262 (pcache->block == ((lfs_block_t)-1)) when writing bigger files e.g. greater than 64 kB?

> IDK if this is possible in your setup, but can you try something similar with SPI flash? That then may point to if it's a generic problem, or an...

So, the funny thing is when I do something like this in a loop: ``` size_t integrity_test(const size_t max_bin_pow) { for(size_t i = 1; i < (2

> Maybe try SDMMC interface and see if the issue still occurs? I will have a closer look later today. So it seems like only ESP32S3 and ESP32 supports this...

> Can confirm this is unlikely to be a littlefs issue. littlefs also doesn't support cross-block/cross-sector writes at the moment so [espressif/esp-idf#7804](https://github.com/espressif/esp-idf/issues/7804) seems a bit unlikely if I understand the...

No other version of ESP-IDF seems to fix this. Also I found another error: `E (27560) esp_littlefs: ./managed_components/joltwallet__littlefs/src/littlefs/lfs.c:1366:error: Corrupted dir pair at {0x22dc5, 0x22dc6}` When creating a file with `FILE*...

Also on this [line](https://github.com/joltwallet/esp_littlefs/blob/fd64733cdf248c7a7eb207db7d28124f8857fe0b/src/littlefs_sdmmc.c#L22) you do some weird thing instead of using the lsf_config_t* c function parameter passed to the function. How do you actually write data to the sectors?...

Ok, so I tried a bunch of different things: 1. I looked more closely at the code of esp_littlefs, but got confused by all this wrapping sdmmc API around littlefs...
