Yes. I tested the EK-LM3S1968 from TI-Luminary and its
on-board is based on FT2232D.
What do you mean by the driver source code? OpenOCD
has the ft2232d codes based on libftdi. It is

hello
Have you use the FT2232 in linux?
Where can I get the driver source code?

hello, everybody
Who can give me a FT2232 manual.
I just study the FT2232 interface.
thank you very much.

Yes it is supported. I do not have access to FT2232H based debugger though.

Yes,I know. But I believe that technology can achieve it.
The big stuffs are too expensive.They do not worth its price.
I want to improve the openocd performance.

Software is one thing. But the underline hardware debugger
needs to be fast as well. For example, I believe those
two ICE you used will have high speed USB interface,
fast FP
But if we can make it as fast as them ,open ocd will be more popular .

This RealView ICE? Pretty high end stuff. You probably
can not compare it to the cheap

RealView 3.1 + ICE(Got From ARM)
We also use the Yokogawa ICE from a Japan Maker.
We got the same speed with the two ICE.

RDI is the "Remote Debug Interface" which is defined by ARM Inc.
You can refer the ARM doc.

hello,
I report the speed I have test.
Transfer rate: 68KB/sec with open-ocd + gdb.
I download 1096208 bytes which consume 160seconds.
To compare, I list the the RDI ICE debugger speed.
I download the 11MB file with only 17 seconds, means transfer rate 647KB/sec.
I test the data with the s
I will test the speed tomorrow, and share the data.
I use the ft2232 chip and drivers

hello
I try to load the program through gdb and openocd.
I seam that the speed is too slow.
By the Way, I use the follow configruration about the jtag speed.
# Limit the maximum speed of the JTAG interface.
jtag_khz 6000
jtag_speed 0
Do anybody have the same experience or know some reason.
