[ECOS] redboot on ipaq

[Weilong Li <weilongli2000 at yahoo dot com>]

I got something wrong when I want to install 
redboot permanently on ipaq.

The redboot ram version is running correctly and
the ethernet card also got the correct ip information.
Under redboot prompt, 
I typed 

RedBoot> lo -r -b 0x100000 /tftpboot/redboot_ROM.bin  
    
RedBoot> fi loc -f 0x50000000 -l 0x40000       
RedBoot> fis init       
RedBoot> fi unl -f 0x50040000 -l 0x40000       

And everything is fine. Until I type

RedBoot> fi cr RedBoot -b 0x100000
Then I got the following message:

An image named 'RedBoot' exists-are you sure (y/n)?
And the problem is that after the message is shown, 
the area where lcd keyboard is become total white 
blank, so I cannot type any characters correctly.

Please tell me what is the problem.

Also, two questions more:
1) After the redboot ROM version is correctly
installed 
on ipaq, can I still be able to bring up the blue bird
screen(by pressing reset and action button together)
to 
restore winCE.

2) I used seriale cable to remotely debug
thread_gdb.exe(the prebuilt version in ecos1.3.1
for pid) on ipaq when the redboot ram version is
running, however, I can connect and download the 
code, but when I am running, I got bus error message.
And there is nothing shown when I connect and download
code(though I can got these messsage on the host
machine when insight is running). So is that redboot
ram version is not used for debugging, just
for download the redboot rom version, and then
flash redboot rom version permanently.

thanks a lot, 

Weilong
