Re: UBOOT2 JMP
On Tue, Feb 26, 2013 at 09:11:53PM -0600, Nathan wrote: “UBOOT2 JMP ” is what displays during bootup using VirtualBox. There may be something broken on x86 support. This is after compiling with: export ARCH=x86 make generic_defconfig make fdisk /dev/sdb...partition...mkfs.ext2 /dev/sdb1 ./scripts/setupmbr/setupmbr –s 32 –m ./barebox.bin –d /dev/sdb I think there may be something I’m missing after “setupmbr” or I need to change a config value after setting “generic_defconfig”. My end goal is to use barebox on my ODroid. I was “somewhat” familiar with syslinux but learned it doesn’t support ARM. I learned that Samsung Exynos in the ODroid uses UBoot and that barebox is the next evolution of uboot. I’m hoping it will be forward compatible (uboot in SoC calls barebox in MBR of SD which calls my linux kernel in SD partition). When you want to use barebox on the ODroid, why do you build it for x86 then? You have to build for ARM. Unfortunately the Exynos is not yet supported, so you would have to do the porting effort yourself.

IMHO there are too many 'UART_CR_TXEN' and 'UART_CR_RXEN' here.
Yes indeed, thanks.

Re: [PATCH 0/5] Zynq support for barebox
Hi! On Sat, Mar 02, 2013 at 07:20:12PM -0600, Josh Cartwright wrote: In San Francisco a couple weeks ago (ELC2013), Thomas Petazzoni informally mentioned barebox in passing, so I decided to toy with it a bit... This patchset adds basic support for the Zynq SoC to barebox. So far, it's only been tested as a 'secondary' bootloader (after u-boot). Also added is support for the zc702 development board. I have some patches laying around, that have support for booting first stage from a SD-Card on a ZedBoard. I didn't send them as of yet, because I'm not completely satisfied with them in one or two places. (The clocksource seems to be inverse to what barebox expects, which would be a quick fix, and barebox boots uuultra slow, if I do everything according to the TRM) At the moment, I do not have access to the board though. But I hope I can get a hand on it in the next days. What I do not have atm is the clkdev stuff, that you already have. Regards, Steffen The first two patches are simple typos I found getting acclimated to the barebox source.

IMO we shouldn't increase the dependency on libfdt. The fdt format is a
nice storage format, but it sucks for modifying the tree.
I created some patches to get rid of libfdt entirely yesterday. They are
not complete yet, but removing libfdt has some nice effects:
- Smaller binaries
- No more parallel universes of fdt and internal trees. This currently
makes the
devicetree code messy
- I trimmed down the overhead of unflattening/flattening significantly.
It still adds some overhead to do it, but manipulating the tree is a
factor of 50 faster which means once you have multiple manipulations
of the tree it reduces the overhead to a net win.
ok will this be availlable for next release ok ohterwise can we have this
patch first so we can have the fixuo support for highbank
I applied this one and the highbank patches using it. I have to rework
My devicetree series anyway, so it will be too late to merge this to
-next before the march release.
