Bootloader Trizeps VI (PXA168)

The 1.1 GHz bootloader will run on Trizeps-VI modules with 1.1 GHz speed-grade.
The 800 MHz bootloader will run on Trizeps-VI modules with 1.1GHz or 800 MHz speed-grade.

View the serial-number-sticker for speed-grade information.

• Put pxa168.nb0 on a SD-Card.
• Insert it into your device and run the bootloader command prompt (Bootloader):

boot mmc pxa168.nb0

Note that there are different Trizeps VI versions. A bootloader generated for A0-processor silicon will not work on the newer B0-silicon!!
The below bootloaders are for B0-silicon. Contact Keith & Koep for A0-silicon bootloader if needed.

• bootloader_tr6_release.txt

There are two version:

• The standard version keeps the pull-behaviour of the display-pins on boot (pull-up).
• The _mod version configures display-pins as pull-down on boot.

You can check the difference in the bootloader by typing:

:) 0xbfd1e0e0 @ .h
4cc0    -> for standard-version with pull-up on boot.
a880    -> for _mod-version with pull-down on boot.

You may also add as first line of your autoboot.bat:

:) 0xbfd1e0e0 @ VAR LCDPAD

to generate a registry-key named LCDPAD in [HKEY_LOCAL_MACHINE\Drivers\Display\Booted Display] with this value.
