Andre, I read all the other thread under your message. I didn't understand what are you trying to do.
i am trying to store the kernel image (uImage) inside of the jffs2-filesystem .. thus i need the fsload command to load it from the filesystem into sram.
If this can help, I can say I am successfully using Dataflash with a couple of different custom boards based on AT91RM9200 (DK like) Please post your u-boot configuration, your memory specification, and what you want to do.
we are using dataflash as well, and it works! but we store the kernel image directly on the dataflash .. if we can store the kernel inside of an jffs2-image which is mounted during the system runs it would be much easier to update the kernel, or am i wrong? that is what the whole discussion is about.
here is some output: <log> U-Boot 1.1.4 (Jun 26 2006 - 16:38:12)
