I don't think there's anything novel here? It's one of those things that every embedded dev kind of cobbles together on their own as they discover the limit of struct arrays stored in EEPROM. Except this one actually seems worse in some ways, because to find a file you have to keep following what is effectively a single linked list of file headers until you find the file you need. The authors even acknowledge this is just a copy of tar's approach, and even acknowledge that that was in turn done this way due to a lack of random seeking on tape systems at the time. But a microcontroller's EEPROM/SPI/... data is nothing like this? You can just do arbitrary seeks. So I'm not sure what they were going for here. The implementation is also full of obvious bugs that will cause crashes or hangs or worse when operating on an untrusted or simply jus
