<p><b>New page</b></p><div>Should you have an Insurrection Industries Carby (GCVideo) device on a pre-3.0 firmware, the only way to upgrade it is via JTAG. You can use a Raspberry Pi to upgrade it. The process is outlined here as a set of notes. <br />
<br />
First get the Xilinx Programming Tools (I used 14.7, in Windows 7) and record an SVF session programming an xc3s200a with an attached m25p40 SPI flash with the carby*.mcs binary. Put the .svf somewhere you can access from a Pi.<br />
<br />
Connect Carby to Pi (I used a Pi 4)<br />

<br />
Get the following packages:<br />
<br />
sudo apt-get install autoconf autopoint libtool libreadline-dev python-dev bison flex<br />
<br />
git clone git://git.code.sf.net/p/urjtag/git urjtag-git<br />
<br />
cd urjtag-git/urjtag<br />
<br />
Build...<br />
<br />
./autogen.sh<br />
<br />
make<br />
<br />
make install<br />
<br />
Run...<br />
<br />
pi> sudo jtag<br />
<br />
jtag> cable gpio tdo=9 tdi=10 tck=11 tms=25<br />
<br />
jtag> detect<br />
<br />
jtag> svf /path/to/svf/carby.svf<br />
<br />
Wait... about half an hour.<br />
