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

Were you doing this using the LCD/touch? If so, the screen
will blank after a few seconds. Simply pressing any button
on the front should bring it back.
However, I would recommend you do this install using the
serial port as console.

Yes.

This is probably a problem of address overlap. It is
possible to load & run programs from the WinCE version,
but you'd need to adjust the eCos build paramters to do so.
Once you get RedBoot installed as the primary image in Flash
these problems will go away.
