Well, there is some time since we have implemented the flash support for our board (Atmel AT91RM9200 based), but at the moment we have done that, as far as I remember it was impossible to support both chips we have. > >> > Flash: 0 kB >> This message is saying that u-boot was unable to detect the flash chip >> itself. >> The easiest way to get you flash working: >> 1. add flash id in include/flash.h (check your flash datasheet) >> > > NO!!!!

The flash organization for this chip is the same as in AT49BV6416 which exists in the sources, so we haven't changed a lot.
So, I think that's all are board dependent what and where are easier and/or faster to implement. > Best regards, > > Wolfgang Denk > > Kind regards, Andrejs Cainikovs. ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
