Re: Redboot v2.04, IXP4XX and Flash v2
Hi,
Sorry,
I forgot to mention that you'll need to add the flash v2 packages to
your ecos.db file so that they are known to the configuration system.
Also, the package that enables your flash support should implement
CYGHWR_IO_FLASH_DEVICE, this will tell eCos how many flashes are
available on your platform.
I'm not sure which package it should be for your setup since I'm not
familiar with your particular setup, maybe someone else can clarify
...
