So far, update "buffer logic" is successful, and self-test is successful.
However, when attempting to connect to a developement board with JTAG port (JTAG port is working verfied by Lauterbach Trace32)

Since JTAG port and bus blaster v4.1a all supposed to be working, I wonder if it's the firmware that's not working?
The firmware I flahsed is from
And the binary comparison shows these two files are identical
I wonder it may mean that once flash with this firmware, bus blaster v4.1a can do nothing other than self-test??
Also, the last sentence on http://dangerousprototypes.com/docs/Bus ... _resources
We highly recommend users upgrade to a non-selftest buffer immediately.
So it make me wonder I need to flash it with a "non-self test" firmware to make it work?
