[Fwd: Hx4700-port Digest, Vol 11, Issue 10]

Hi Philippe,
Thanks for your help.

Do you mean that there are essentially two steps, providing one doesn't wish to backup
the WinCE to an SD card and that one decides to use only an SD card instead of a CF card?
(I have one spare 256Mb SD card lying around that I could use, but I don't want to sacrifice
my 4Gb CF card to the hx4700.)

i) dd if=bootldr-1.1.9.rom of=/dev/${SD_DEVICE}
        press <Contacts>+<iTask>+<Reset> & follow instructions.

ii) Use a second SD card that contains reflash.ctl, zImage, homefs.jffs2 etc on it.
        press <Contacts>+<iTask>+<Reset> & start the reflash process.

In this case I need to two SD cards (or 1 x SD and 1 x CF), or can I use one SD card for the
ROM install and then reuse the Sd card for the second stage?

Things are a little cleaer now,
Simon.

And then read bootldr.txt

This step is only needed if you want to make a backup of the complete
contents of your flash (i.e. backup WinCE). It uses the original HTC
bootloader to dump the whole flash onto an SD card. Using CF here is
not possible as the HTC bootloader doesn't support this.

You should use the newest one (1.1.9) as it has the most recent
suspend/resume code needed by newer kernels. You can't install this
second-stage bootloader using a CF card as the original bootloader,
which is used to install it, only understands SD.

# dd if=bootldr-1.1.9.rom of=/dev/${SD_DEVICE}
Pop in the SD card, then press <Contacts>+<iTask>+<Reset> and follow
the on-screen instructions (no backlight).

Once you have the SDG bootloader installed, if you press
<Contacts>+<Email>+<Reset> it starts the reflash menu. It will read
reflash.ctl from CF and allow you to flash (1) kernel image, (2) root
file system and (3) home file system.
Your CF must contain reflash.ctl, zImage, homefs.jffs2 and some
rootfs-*.jffs2 with those three listed correctly in reflash.ctl (which
should be the case if you downloaded them from one place).

As always, once you've done it, it seems rather easy.
