Hi,

I m U-Boot-SH Maintainer.

> I wanted to know, what boot-loader would suit best, for a board based on SH7763, I couldnt not find an u-boot for this CPU, RedBoot although has support for SH4a, couldnt find any for this specific cpu.

I'm writing it. I will commit my git repositry in this week.
Please wait.

Best regards,

Hi,

Thank you, I would also like to know, something about the development environment, If I want to write a new flash driver, or new ETH driver, and support them from u-boot, what best would be my environment ?

Because I would like to use a debugger (jtag/ICE) kind of a tool to debug symbols, put break points in u-boot, so is there anything like the GDB kind, for this ?

Thanks,
Pavan

What does environment indicate?
Is it a compiler?Or, is it OS?

U-Boot-sh doesn't support GDB now. And I don't use it.

If you want to use GDB, need suport.

CC ed the u-boot mailinglist, because its more a u-boot topic. I used to
compile the u-boot
for a sh7750R based board (Sorry, patches for u-boot not posted yet ...)
with the
compiler from

http://www.sh-linux.org

There is also a fine readme.txt for installation.

or use crosstools for making a compiler for your needs. See it at:

http://www.kegel.com/crosstool/

And then, hack the code ;-)
If your Flash supports CFI it should work with the CFI driver in u-boot.
Look in the u-boot readme how to start/modify the u-boot code.

bye

On a somewhat related note, what is the status of the SH7203 patches? I
have some SH7206 and MX-G bits that build on top of them, yet I don't see
any of the SH7203 stuff in the git tree?

I don't touch SH7206 and MX-G.
Do you know someone is doing the work such as MX-G? 

About SH7203 , I will put code to U-Boot 1.3.5 queue.
