[linuxsh-dev] LinuxSH bootloader?

[Tim R. <Ti...@Ri...>]

For those of you running native Linux machines, what are you using for a
bootloader? I've found the link:

http://LinuxSH.free.fr/faq/linux-romimage.diff

But I was hoping for something that could handle flash updates etc like
the blob project on ARM/StrongARM/XScale:

http://www.lart.tudelft.nl/lartware/blob/
http://sourceforge.net/projects/blob/

Are there any open source boot loaders around?

The device I'm building for will not have an ethernet connection and I
don't fancy loading kernels over JTAG all the time. serial console with
reflash ability would sure be nice.

From what I can tell the "PFM-DS11 monitor" runs directly from flash so
I can not update the flash region it is running from. I also do not know
if it can be convinced to "mv" and "g" on startup. I'd like a timed boot
of the kernel with default options, as well as the ability to interrupt
the boot and upload new kernel/ramdisk/bootloader versions to flash and
hopefully boot a kernel with command line arguments passed to the
kernel.

Any ideas?

Oh, not sure where you folks hang out. I started a #LinuxSH on
irc.openprojects.net (irc.freeport.info) and I'll be hanging out there
while on this project (I go by BZFlag).

Any admins for the SF project that would add TimRiker to the project
would be appreciated. ;-)

#linux-sh has been around on OPN for the longest.  Could you use it instead?

Why?

I ported blob (1.0.8 version) to an sh-4 platform, but I left the flash
writing out.

I think there are very few changes needed for different boards. Probably
only sdram and scif initialization.

Why do you need the reflash ability in the bootloader. After you load
kernel and ramdisk once over serial, you can write to the flash.
