The automobile has transformed into the most sophisticated electronic device in the market. If you use NXP’s SPI drivers, especially the DMA ones, watch out – they have a ton of overhead and give horrible performance for short transactions, like if you’re sending a write enable command and then a page write and address separately. Improve INSERT-per … Learn how your comment data is processed. Each file object (if it’s not in tiny mode) has its own LBA-sized cache and there’s no registry of open files so I’d probably have to be a modification to FatFs itself to attach a counter to the object and force a reload from flash when it’s accessed. You might also have cache_ftl.c. Use Git or checkout with SVN using the web URL. Once you’ve got FatFs able to talk to your flash chip, you’ll use the f_mkfs() command to format it and f_mount() to mount it.

How to write to STM32 Flash-1. GPL-3.0 License Releases No releases published. My library first verifies that the write is possible (memory bits can be programed to '0' only), if a bit is already '0' and needs to be a '1', it copies the corresponding sector to the SPI RAM, initiates a Sector Erase, merges the new data into the SPI RAM image, then after the Sector Erase Completes writes all non '0xff' bytes back into the FLASH by 256byte pages. Arduino Micro 12. My driver (at least in some versions) deals with that by intercepting MBR writes and tracking that bit in RAM so that reads are consistent (and the host OS won’t freak out if it’s trying to format and verify or something) but it doesn’t actually have to erase and rewrite the sector. Link is fixed (thanks for reporting! It’s not thoroughly tested yet and I’m not sure its behavior will be correct when the drive fills up, and it really needs to support the trim ioctl for efficiency.
