Would it be possible to use the gpio port on a raspberry pi as a JTAG programmer?
Has it already been done?
I've been monitoring this forum, but not seen a mention of raspberry.
The RasPi is already implicitly supported via the gpio driver in UrJTAG.
Get the following packages:
sudo apt-get install autoconf
sudo apt-get install autopoint
sudo apt-get install libtool
sudo apt-get install libreadline-dev
sudo apt-get install python-dev
git clone git://git.code.sf.net/p/urjtag/git urjtag-git
Edit the file cmd_bfin.c in src/cmd and add the following line at the top:
This is to avoid conflict between blackfin defines and system includes.
pi> sudo jtag
jtag> cable gpio tdo=9 tdi=10 tck=11 tms=25
Create a JTAG cable with the following pinout:
Pin Name Raspberry Pi (GPIO Header)
Based on an initial post by: WolfNexus
How do I (find out and/or tell) urjtag which gpio number represents the TRST and SRST signals?
