How to correctly read a file from an mtd device?

Question

linux

Good day!
On Linux, there is a device /dev/mtd1(nand-flash) where the uImage is copied with the usual cp command, i.e.:
#cp /tmp/uImage /dev/mtd1
If I want to extract the uImage and copy it to another partition, is it enough do something like:
#cp /dev/mtd1 /dev/mtd5
or is there another way?

Answer 1

Use dd with the desired block size (bs=number). EMNIP, nand has page addressing, so it's better to specify bs as a multiple of the page size.
