I am using a STM32 Cortex-M3 and just recently got FatFS up and running with a SD card in SPI mode. I would like to modify the disk_read() and disk_write() functions to use DMA transfers. I understand how to use the DMA peripherals to transfer the data, and how to enable the DMA interrupts so they are triggered when the transfer is complete. is there any known differences between the littlefs firmware and the fatfs firmware? the reason i ask is we have a program with a local webapp for reading a sensor and a config.html for setting setpoints. i just updated a new batch of wipy 3 and decided to use the littlefs file system as all our previous versions used the fat.

Hello my friends, I'm really confused about the Chan's FatFS read-function! I'm able to write and do loggings etc... but reading a file greater than 1 kB doesn't work! I can read up to 1 kB (not including 1 kB). The problem is I see only 0 (zero) above 1 kB! My buffer is 2 kB, so it's not the bufferproblem. Return Value. This function returns zero if successful, or else it returns a non-zero value. Example. The following example shows the usage of fseek() function. Littlefs File System Sample Application¶. Overview¶.

LittleFS is an independent mbed os based system that could potentially work with another FreeRTOS based system. LittleFS works with a FAT file system backed by either an secure digital card or NOR Flash memory. I will get back to you on the performance related information.

Jan 11, 2019 · FATFs for projects, this is ok as long as one requires FAT support (on SD cards for example) but for embedded systems that must be resilient to sudden poweroff conditions, its a no-go why?
