Hi I am working with stm32L152VD. I need to store about 100MByte measured data in a relatively low price chip. Is using NAND Flash the only way? Is there a way to store data in a none-file system in NAND flash?
NAND, and SD Card, are reasonable options. Depends on the number of available pins, external memory interfaces.
You don't have to use a file system for anything, as a programmer you have ultimate control over how you use memory devices. NAND uses quite large memory blocks, and requires you to use error-correction techniques.
Thanks for your advise.
