Comments on: Bus Pirate: Firmware upgrades http://dangerousprototypes.com/2009/07/24/bus-pirate-firmware-upgrades/ A new open source hardware project every month Fri, 12 Mar 2010 15:59:20 +0000 http://wordpress.org/?v=2.9.2 hourly 1 By: Brett http://dangerousprototypes.com/2009/07/24/bus-pirate-firmware-upgrades/#comment-7 Brett Thu, 07 Jan 2010 11:47:59 +0000 http://dangerousprototypes.com/?p=33#comment-7 Here's a cool tip if you're flashing your BP often with the P24QP application and you have to change the COM port setting and/or speed.... Edit the P24QP.INI file that is in the same directory as the application itself. If your COM port setting needs to be changed as per step 1 in the image above, change the line that says portindex=2 to be what your COM port is, in my case COM5, so my file says: portindex=5 If you have succeeded in programming at a faster speed, you can default the setting to that as well !! In my case it seems to work at 115200 as Ian does, so I want it to default to that. Change the line that says bitrateindex=4 to be: bitrateindex=8 (the index values are 4=9600, 5=19200, 6=38400, 7=57600, 8=115200) There you go. Save the file, and start P24QP, and voila! No more changing the port and speed. In my case I kept forgetting to change the speed before I connected to the device, which requires you to unplug the device and re-start the bootloader to get the additional speed - now, no longer a probelm !
