Only press check for bootloader if your intention is to only check if a bootloader is present.

Bus Pirate Development / Re: Higher serial speeds?
In bootloader firmware
Change the following lines (they already exists)
.equ UARTBR, 0
;.error "Baudrate error is more than 3%. Remove this check or try another baudrate and/or clockspeed."
;bset UMODE, #BRGH ;enable BRGH
In GUI
Baud rate: 1000000
With the above settings, the entire flash is written in 6,9s on my pirate/computer.

Bus Pirate Development / Re: bootloader v4 console utility
[quote author="ian"]
There is also a ds30 Loader console, but it hasn't been updated with the new features that were added for us.

The flowchart in firmware manual might be interesting for you.

Bus Pirate Development / Re: Bootloader v4 (ds30 Loader)
One user wanted fast start of user application at boot (<30ms), he modified the bl to have separate timeouts for startup and comm.
100ms is probably a good balance between reliability and waiting. Dont forget to lower the polltime in the gui.

You mean post increment? That makes sense.
#1 I believe the write will only occur in on the selected row even if you load the latches in another row.
Code: [Select]
mov.b #0x04, W0
mov.b W0, [WBUFPTR++] ;upper byte
mov.b #(0xff & STARTADDR), W0
mov.b W0, [WBUFPTR++] ;low byte
mov.b #(0xff & (STARTADDR>>8)), W0
mov.b W0, [WBUFPTR++] ;high byte
mov.b #0x00, W0
mov.b W0, [WBUFPTR++] ;upper byte
mov.b #(0xff & (STARTADDR>>16)), W0
mov.b W0, [WBUFPTR++] ;low byte
mov.b #0x00, W0
mov.b W0, [WBUFPTR++] ;high byte

Bus Pirate Development / Re: Bootloader v4 (ds30 Loader)
Yeah thats what has probably happened. Here's a few thoughts:
* The gui doesn't erase pages that is not found in the hex file, option to add?
* settings.xml should be write protected?
* Don't let the gui start if settings.xml is absent?
* Let the bootloader set the 0x00 goto itself when it detects a write to row 0?
edit: I really like that expression, to NOP. Maybe it could be use irl also: "I was noping at work today" =)

Bus Pirate Development / Re: Bootloader v4 (ds30 Loader)
What exactly did you do? Should be pretty hard do corrupt the bootloader unless you download with the
incorrect custom bootloader placement.

Sjaak: "...But during flashing the app crashed (I think only the GUI, because the USB led was still flashing during the popup) I forgot the write down the error because i was scared. Second try it didn't crashed. I really like the app btw!"
The ds30 Loader GUI crashed during download? Did you have debug mode enabled? If so, do you know what was going on at the moment of the crash (unhandled exception)?
Did anyone else experience crash of the ds30 Loader GUI?

Where you from Alex? I'd like to add you to my contributors list on the homepage
for the gui code.
Hope I get my pirate soon so I can test to

Bus Pirate Development / Re: Bootloader v4 (ds30 Loader)
same time I've done some major rework of the code in the engine. I have reduced code by approx 30%.
A lot of the hex parsing and writing code is common for most firmwares...
Here's a new version that I hope will be the next official release:
http://mrmackey.no-ip.org/elektronik/ds ... loader.zip
https://mrmackey.no-ip.org:444/svn/ds30 ... k/pc-side/
(The old version should be good enough for alpha testing)
This time you beat me to it, you replied while I was typing
