Lpc2000

Hi Guys,

I'm trying to get a connection to my LPC2104 with also the JEENI from 
EPI, but without succes. Is it really not possible to use the JEENI 
for this uC? I have the new firmware (v2.2). 

Rev 2.2 firmware performs a self-test to verify that the JTAG 
connection to the target is working properly. The JEENI puts the JTAG 
TAP into BYPASS mode, writes out 32-bit pattern of ones and zeros 
(0x59A6956A) and tries to read it back.

(JTAG TAP CONTROLLER)
On my scope I see that more then 5 cycles of tck with tms '1', so the 
LPC is in test logic reset. Then its going to select IR-SCAN and goes 
to capture-IR and four times shift-IR with TMS '1'. Is this a good 
instuction for the LPC2104 to select te BYPASS register???? is the 
opcode only 4 bits????? I cant find information about that on the 
philips website.

Then I see it goes to select DR scan and writes the pattern of ones 
and zeros. Later it wants to read it back, but the TDO stays '0' and 
the error JTAG ERROR TDO=0000.0000 appears (from the firmware). (TDO 
is connected fine, so thats not it)

Does some of you know more about the tap controller and instructie 
register of the LPC210x or where I can find that and more about the 
compactability with the JEENI?
