i have a little project working on stm32f415, with a task producer and a task consumer, between i want put a SdCard ( with fat ) like cache, because if something going wrong during trasmission or consumer is busy for some reason, i not lost the data.


Add all data at the end of file is not a problem, but it's possible take packet from start address and shift all the data in easy way ?


I can't read entire file because can be also some megabyte of space.


So i think i need to use a file on Sdcard like FIFO.


Sorry for my english
