I am embedded software developer and working mostly with ARM Cortex microcontrollers in C. I created many embedded projects, which works as USB host/device, uses TCP/IP and filesystems on NAND/NOR flashes/SD card at HCC Embedded now Tuxera Hungary.

Another solution to access files from PC is the MTP (Media Transfer Protocol). This protocol is used by cameras and some Android phones too. The MTP provides file...
I recommend SafeFAT which is a journaling filesystem. It protects data integrity too. SafeFAT is compatible with FAT, so the files on SD card can be read/written...
Not only the filesystem matters: commercial SD cards use caches and simply not designed to power cut during write. So they often die if you remove it during write...

Hello,have you got FTL (flash translation layer)? It could be a bug in the implementation of FTL. If you don't have an FTL: using FAT filesystem on a flash media...
There is some misunderstanding: you cannot recover data using checksums. You can only determine that data is good or bad. That is the problem with a half-written...
Hi,Probably not only the software was faulty: a file system cannot be "power-off safe", fast and efficient at the same time, when the HW is not designed properly. If...

Hi,If you are fed up with 'frozen' development tools (or trouble with licences), you should consider Lattice FPGAs. There are open source development tools for them!...

Hi aatif shaikh,Removing the files from /dev surely not enough. If you want to change those registers from user-space, you need to compile a small C program or...

Hi,UART (or any other peripheral) and GPIO cannot work at the same time. There is a multiplexer inside the MCU which selects the working functionality. If you...
