Hi Nick,
read <filename> <startaddress> <length> Reads data from RAM into the specified file readflash <filename> <offset> <length> Reads data from the NAND flash (very, very slowly)
Is it the distinction between RAM and NAND flash that's confusing you? Otherwise, they're pretty similar.
Not beaning funny but posting on here is hard, I have never used email so much,well I don’t use email
It's always a good time to learn to use email properly. It's the core of many projects' communications. Lots of data can flow into email, e.g. RSS feed readers, and cron-job output. And there are many programs that can read it, search it, and store it as a text file per email for access by the normal Unix text processing tools. Email is king. :-)
