Hi Stefan,
I work with Archie. The build described above was done with foc_imx53 as base. All right, we'll rebuild the system with hw. The link that explains TFTP boot using u-boot only describes Panda. Is there a script for imx53. If so, where?
no there isn't. Nevertheless, the way how u-boot handles loading files via network, or sd-card, or whatever has in general nothing to do with the platform it is running on top of, nor with the operating system it tries to load. In contrast to that, the binary of u-boot of course is highly platform specific. Therefore, the way how to load files via network can be done the same way like on Pandaboard. The only difference as far as I remember correctly is: on i.MX53 you don't need to initialize the USB Host controller in u-boot to use network, because its network controller isn't connected via USB. In short you don't have to trigger 'usb start' like on Pandaboard. So the steps you've to do are:
# either 'dhcp' or 'setenv ipaddr xxx.xxx.xxx.xxx' # 'setenv serverip xxx.xxx.xxx.xxx' as long it isn't set via DHCP # 'tftp 0x70800000 [path_to_uimage]/uImage' # 'bootm 0x70800000'
If you are playing with different ARM hardware platforms, and trying different OSes on top of it, I strongly recommend to you to study the u-boot documentation, and get an initial understanding of its working.
Regards Stefan
Thanks and Regards Amit

Hi, I've forgotten to ask: are you using the 'hw_imx53' or 'foc_imx53' base platform? I just ask, because the Fiasco.OC kernel version currently used by Genode is known to not work properly on i.MX53 QSB: https://github.com/genodelabs/genode/issues/704 So, please only use 'hw_imx53' at this time.
