I think the bootstrap command in PalmDebugger was used only when the EZ
Dragonball CPU was in "bootstrap" mode.  The bootstrap mode of the
Dragonball CPU can only be entered if you connect some sort of button to the
appropriate pin on the CPU itself.

Some Palm development platforms (used by Palm Licencees) have a bootstrap
button.  When the bootstrap (B/S) button is held down during a reset, the
CPU will enter a special B/S mode.  In this mode, the CPU switches to
dedicated microcode, which allows a Motorola-provided program, BBUGV, to
transmit raw hex data to the platform, which can be subsequently executed.
The uploaded raw hex data is typically a smallROM image which is then
started, so it can be bootstrapped to allow initial flashing of a 'blank'
flash chip.

Now, with all that history, if you actually wanted to do something as risky
as flashing a real, physical Palm device, the PalmDebugger command you want
to use is the "flash" command.  The old bootstrap command in PalmDebugger I
think is old, and only worked with EZ Dragonballs (I don't think it works
with VZ-based Dragonballs).  Also, BBUGV is a better program for
bootstrapping a Dragonball.

Also, I'm not sure if the FLASH command works in the released version of
PalmDebugger or not.  It may only be fully functional in a special version
called FlashablePalmDebugger, which is used by Palm Licencees.

I flash ROMs on our development board all the time, but I have nothing to
lose, as I can always re-bootstrap a corrupted flash.  But I've never
actually flashed a real Palm device, because I think it's much riskier.
This doesn't mean you can't do it, but I'm not sure of any "safe" way to do
it, or what publically available tools are out there.

Subject: Using the 'bootstrap' command in the debugger


Hi,
How can I use the 'bootstrap' command of the Palm Debugger to run Debug ROMs

on my Palm devices? The documentation talks of a "hwInitFile", but I can't 
find more details on that. Has anyone compiled a series of steps to flash 
Palm Devices with Debug ROMs?
Thanks,
-Prashant
