- The CPU can execute code directly from NOR flash...

- NOR flash is very convenient for bootloaders, which do not have to be copied to RAM before executing their code...

- The CPU cannot execute code from NAND without copying the code to RAM first...

- NAND flash devices can come out of the factory with faulty blocks... bad blocks!!!...

- Do not put a swap area on flash storage...

- Whenever possible, mount your filesystems as read-only...

- Keep volatile files such as log files and locks in RAM (tmpfs)...

- For small partitions, JFFS2 filesystem will be the best option...

- For medium to very large partitions, UBIFS will be the best compromise in terms of speed, size and boot time...
