[U-Boot-Users] Howto store kernel in AT91 flash

[kentropy]

Using AT91rm9200DK and u-boot 1.1.3 I wonder how can I store uImage and ramdisk into flash memory avoiding to load them from tftp server each time.
Could someone provide me a simple example of u-boot commands and parameters or a link ?
TIA

Will you please just read the manual?

Thanks.

The parallel flash is 2 Mb. Here you can store u-boot and a linux kernel 
as written in the u-boot manual. For a root fs, the space is not very big...

Another possibility is, to use the serial dataflash for everything, 
which is 8Mb. This procedure seems to be unsupported by u-boot, since it 
copies u-boot from serial dataflash to RAM and starts it, but it works 
for me. Initialization of processor and RAM ist done in this case by a 
pre-bootloader (romboot).

The procedure is described here:

Sorry, maybe I searched in the wrong place
I read here:
http://www.denx.de/twiki/bin/view/DULG/Manual
and in detail here:
http://www.denx.de/twiki/bin/view/DULG/LinuxInFlash
where you say 
"Below is a transcript of the complete operation with a final iminfo command to check the newly placed Linux kernel image in the flash memory."

But there is not example about howto store images in flash.
Could you please point me in the right direction ?
TIA

this command will store in flash (target) the image previously loaded in ram 
(source) which is (count) bytes large.
cp.b source target count

This procedure is for u-boot-1.0.0, maybe has been included into 1.1.3 ?

At least, it works for me in u-boot 1.1.2. I guess, venen the newest 
version might work. You don't even need the patch mentioned there, at 
least not for u-boot 1.1.2. You only have to set the correct #defines in 
the board specific config file...
