[ECOS] Problem with building redboot on sh4(se7751)

[ECOS] Problem with building redboot on sh4(se7751)

[koji]

Hello

I wanna boot linux on the Hitachi SH4 Solution Engine 
SE7751(HD6417751F167) with RedBoot.

At first I built redboot by ecosconfig with default platform RedBoot 
configuration file. 
The ecos version is 2.0b1.

$ ecosconfig new se7751 redboot
$ ecosconfig import ${ECOS_REPOSITORY}/hal/sh/se7751/VERSION/misc/
redboot_ROM.ecm
$ ecosconfig tree
$ make

and wrote redboot.eprom.srec into flash.

Ready > fl

$ cat redboot_ROM.eprom.srec > /dev/ttyS0 

After that,
It booted from flash,I could'nt see boot message, 
only see
 
" ++++++++........ "

The serial setting of target board is 38400 8N1.
I set Minicom by same parameters.

So I'd like to know if I need to modify configuration  of building 
redboot or special hardware setting.
Is there anyone who succeed to boot from flash on the se7751 board ?
please give me advice.

Koji Yamamoto

Looks like the + could come from the GDB stub, but I have no idea where 
the dots come from in that case - looks like it could be the se7751 boot 
loader.

As per http://sources.redhat.com/ecos/docs-latest/ref/se7751.html did you see:

Start Addrs = A1000000
End Addrs = A1xxxxxx
Transfer complete

when the cat finished? If not, that would imply it didn't work!

And no flow control?

Sorry, not me - I'm only replying since no-one else offered suggestions.

Thank you for your replying.

Sorry, my explanation was poor.
I did each steps in that URL.
I can see complete finish writing message.
After that I check memory with some command.
I think it's completed successfully.

And minicom setting is 8N1 and no flow control.
 
Now I change board 7709s and edit cdl file and source file.
about value of real-time clock/counter or Bus State Controller.
And I succeeded in changing LED pattern.
But I still can't see boot message.

Now I suspect serial driver.
Anyone have Information about serial driver?
