Title: Compiling from source
Post by: jayb1239 on March 16, 2013, 09:10:26 pm
Hi,
I wonder if somebody could provide a little assistance.

I am trying to compile the BPv4 firmware from source.

I cloned the SVN and opened up the project in MPLAB 8, I then modified the base.h and commented out the v3 (tried with and without comment) and then tried to make.

The build reports to go successfully and I get a hex in the output dir which is 339kb or if I export using the default end I get a file of 962kb but flashing either of these via pirate-loader does not work. The pirate-loader reports success but the bus pirate does not boot.

This is probably something silly that I am overlooking but from my reading around the forums and trying to find a solution myself I am getting nowhere.

Any suggestions

Thanks in advance

BPv4 uses USB and another PIC microcontroller. There should be a second MPLAB project file in there, try opening that one.

I have tried building with MPLAB & MPLAB X with all projects in there (the MPLAB x project, the BusPirate project and the BPv4 project. The hex flashes fine, but the bus pirate isnt enumerated when plugging back in :-(

OK, found the problem: In base.h, look at lines 127-129:
Code: [Select]
//Debugging mode for BPv4, comment out for normal compiling
//Adds alternative communicaton to UART1 over AUX1 and AUX2 instead of USB.
#define BPV4_DEBUG
You have to comment out line 129. Then it works.

sorry for that, I'll comment it out, and recommit to SVN so it's off by default..
