[U-Boot-Users] u-boot on N810

Hi,
Does U-boot have support for N810? I tried booting u-boot from TI for OMAP2420 on n810; it didn't work - this is what i did :-
- took u-boot (ELF) from TI's website for OMAP2420 (http://linux.omap.com/pub/bootloader/h4/) - invoked objcopy on u-boot.elf to convert it into u-boot.bin - loaded u-boot.bin as kernel(zImage) for n810
Did I do something wrong? Am I missing something?
Thanks, Ashish

Wrong here. This is for 2420 development platform that you see here: http://www.ti.com/omap2420_devplatform

Thanks for the response. Does u-boot support n810? Can I flash u-boot on n810? Thanks.

No, you would need to port u-boot to the hardware. The OMAP and the necessary built in peripherals shouldn't be a major problem, but you would have to get the rest of the hardware like the SDRAM and other bits & pieces initialized/configured before u-boot will run on the hardware.
Be aware that you need to be very good and extremely lucky to load a new u-boot without bricking your n810. If you try flashing u-boot, you better have an alternate means of reloading the firmware (i.e. a JTAG debugger).
I'm curious: why do you wish to replace the n810 firmware? The current firmware initializes the hardware and boots linux... those are the usual primary reasons for porting u-boot to new hardware.
gvb P.S. I have a n800. It would be cool to have u-boot running on it, but I don't see the pain vs. gain paying off.

hey jerry...thanks for the reply....i don't wanna replace nolo with u-boot...i just wanna nolo to load u-boot instead of loading the kernel directly....the reason is that i wanna load l4 based hypervisor image first and then linux on top of it....current loader (nolo) is linux specific and wouldn't allow me to load the hypervisor at any random place in memory
can nokia flasher load and boot the kernel image without actually flashing it? if yes, could you please mention the details...thanks

Hi Ashish,
Please bottom post.
You are way beyond my experience base with the n8x0. You might be able to get better answers on a Nokia (maemo) email list(s). http://maemo.org/community/mailing-lists.html
WRT u-boot, I don't see how using nolo to boot u-boot to boot L4 is going to be any easier than booting L4 directly from nolo.
You might look into using kexec to chainload your L4 hypervisor. Kexec is the linux program to load a new kernel, theoretically you could do that with L4 too. Google is your friend. The following looks useful: http://www.ibm.com/developerworks/linux/library/l-kexec.html
Good luck, gvb
