BUILDING
|
| 5 |
|
|
|
| 6 |
|
|
This program doesn't use automake. It has been developed using the cygwin
|
| 7 |
|
|
environment under winXP, and should also compile under various GNU/Linux
|
| 8 |
|
|
distributions. There are two sets of build flags defined in the Makefile,
|
| 9 |
|
|
one for cygwin and one for Linux - one set is used, one is commented out.
|
| 10 |
|
|
Edit the Makefile for your system, type "make," and see what happens...

DEPENDENCIES
|
| 13 |
|
|
|
| 14 |
|
|
Adv_jtag_bridge has three dependencies:
|
| 15 |
|
|
|
| 16 |
|
|
- The pthreads library (probably already installed)
|
| 17 |
|
|
- Cygwin only: libioperm (for parallel port device access permissions)
|
| 18 |
|
|
- libusb
|
| 19 |
|
|
|
| 20 |
|
|
Since adv_jtag_bridge was written, a newer version of libusb has been
|
| 21 |
|
|
released (1.0), which used a different interface. We still use the old
|
| 22 |
|
|
interface (0.1), so be sure you install the "compatibility layer" if you
|
| 23 |
|
|
install the latest libusb. As of December 2008, libUSB-Win32 still used
|
| 24 |
|
|
v0.1, so cygwin users may not need to install any additional compatibility
|
| 25 |
|
|
layer.

BUGS
|
| 28 |
|
|
|
| 29 |
|
|
GDB 6.8 has a bug which prevents it from working when no stack frame is
|
| 30 |
|
|
present (such as at start-up on a bare-metal debugger, such as this one).
|
| 31 |
|
|
A simple patch applied to GDB 6.8 will work around the problem (a general
|
| 32 |
|
|
solution is not yet available). This patch can be found in the source
|
| 33 |
|
|
directory of adv_jtag_bridge as "gdb-6.8-bz436037-reg-no-longer-active.patch".
