Re: [U-Boot-Users] Start with u-boot on at91rm9200 on AT91RM9200-EK
Hello Marco, my Board doesn't have any Software, the Flash is empty and so i start from the internal ROM - clearly. But now i must do a Download on the serial Port of loader.bin which then does a serial Download of u-boot.bin. This is the Atmel described way to initialize a "new" System or to do an Update. But with the original u-boot Sources 1.1.1 or 1.1.4 the generated u-boot.bin doesn't run, the Atmel delivered binary u-boot.bin does. So i'm looking what to do with u-boot, so that it is loadable like the Atmel one. Who knows if there are any #defines to set (especially for this CPU/Platform) or where any Dokumentation for this can be found ? THX Thomas

Hello Marco, thanks for your Tips - i searched since Monday for any hints !!! It seems that Atmel has done some work on u-boot but
doesn't tell this
their Customers ;-) Your "Howto replace u-boot..." is half the solution of my Problem. I have new Boards without any SW, the Flash is empty. So i want to Xmodem loader.bin and with this the u-boot and
with this
anything what does a boot out of Flash to u-boot :-)
Can you tell me, what to do to reach this ?
Thomas, if you have to program NOR parallel Flash you simply need to Remove the resistor R159 on the AT91RM9200-DK to start the processor from its internal boot ROM. Read the Datasheet
In any case for your (and other) reference I added some links here http://www.koansoftware.com/en/art.php?art=90

No, this is not so clear at all. You can for example just program the U-Boot image to flash using a JTAG debugger.
This is the Atmel described way to initialize a "new" System or to do an Up date.
As mentioned before: please conatact Atmel support with questions about or problems with the way Atmel recommends to do things.
Here we support the public U-Boot code only, not some vendor provided (and most probably obsolete) versions.
But with the original u-boot Sources 1.1.1 or 1.1.4 the generated u-boot.bin doesn't run, the Atmel delivered binary u-boot.bin does.
Your statement is wrong. The images run perfectly fine here both on a AT91RM9200-DK kit and on a couple of custom boards.
So i'm looking what to do with u-boot, so that it is loadable like the Atmel one. Who knows if there are any #defines to set (especially for this CPU/Platform) or where any Dokumentation for this can be found ?
Please READ the previous replies you got. I wonder why I take the time to answer your questions when you ignore my replies?
