In a next step I plan to use the memory with a file system, more about this in a future article. I’m planning to add an option for cached reads that will use DMA to continue the read to fill up the cache block in the background, so it’ll return the requested LBA and then if the following LBA is requested it’ll already have a head start, and might have finished it already. I am attempting to communicate with a winbond memory chip over SPI with the STM32L4VG. It can either use DMA if it’s running FreeRTOS and other tasks can run while it’s reading, or it can block and use polling mode and will switch to 16-bit transfers if you’re reading more than a few bytes, which gives a performance gain of about 6% by eliminating an idle bit between words. disk_read() – Reads one or more LBAs from serial flash (but I’ve never seen it request more than one LBA). This way even with the cheap flash that’s only good for 10,000 erase cycles, you still have a very long time before burnout. The typical usage of external SPI flash memory is using it to load or store data. 1. Arduino Due 4. CS: SPI Chip Select A red LED on the breakout module indi⦠but i don't know why?
