[ECOS] Help with Redboot

[manohar kalyan]

Hello,

I want to port redboot on Atom D510 development board and I have tried a lot of ways, including some methods which were given in the mailing list but was not successful. Most of the methods given in the mailing list use floppy drive to port redboot on their boards, but unfortunately, the board which I am working on doesn't have floppy drive and has USB ports.
 
Can any one please guide me in this regard? I have Intel Atom D510 development board with USB ports and no floopy.and I want to port redboot on it so that I can communicate with a serial port and run programs on the board.

Thank you,
Manohar

It sounds to me like you are trying to load Redboot, not port it. I'm
not sure which one you mean for sure, but if you actually want to do
port Redboot to ecos, the you should have a look at the Porting Guide
in the docs:

http://ecos.sourceware.org/docs-latest/ref/hal-porting-guide.html

Since the Atom processor implements Intel's IA-32 instruction set, it
is an x86 platform and eCos/Redboot should need minimal porting effort
to get running, depending on how many peripherals you need on your
board.

Might I suggest the following (assuming bootable USB):

1. Format a small USB flash drive partition EXT2
2. Install grub to the drive
3. Obtain memdisk from the syslinux distribution
4. Configure grub to load memdisk as your kernel, specifying your floppy
image as the initrd.

A few time ago I was dancing with GRUB2 to get it working :-)

If you install *GRUB2* on your USB stick (Ubuntu users), then enter on
the grub's prompt:

grub> insmod multiboot
grub> multiboot (hdX,Y)/redboot.elf
grub> boot

Then i386 RedBoot[GRUB] started on my Laptop from USB pen.

NOTE: (hdX,Y) means something like (hd0,1).

[ECOS] help with redboot

[j.burton]

Hello everybody, you're so kind, I received a lot of help from you and I
would like to thank you all....

I need a tip for redboot....
Using ecos configuration tool I made those file (template was XF55 of Falcom):
redboot.bin, redboot.elf, redboot.img, redboot.srec...

Now .. how do I download them on my device?

My device is STEPP II of Falcom...
I use an evaluation kit and the SirfFlash Tool for downloading firmware and
application files...

Should I proceed in the same way with redboot?
I tried to download redboot.bin but nothing seems to work... following documentation
using telnet I should see the redboot start up monitor with the CLI waiting
for commands

Did I make something wrong?

Thanks for your help---
