Hi everyone, Because my wiggler didn't work (see topic: Wiggler by theeuwke), i've got from an other department some nice equipment; a JEENI and an MAJIC from EPI. But stil, I can't get this stuff to work. First some info: I have two boards; first one is an EVBA7 from Ashling; http://www.ashling.com/datasheets/DS266-EvKitLPC2000.html It has an LPC2106 microcontroller (ARM7TDMIS) To debug with this board, I set the Secondary debug jumber on enabled, the primairy debug jumper on disabled, the onboard debug on disabled, and ISR on disabled. I flashed a program to enable the secondary JTAG port that was delivered with the board, but I also tried the one in the files section. I just connected the device with the JEENI and the MAJIC with a standard 20 pin connector, that commes from EPI. When I use the JEENI, and try to connect with GDB, it complanes that "Target World is Broken" ?. If I use Debugger from ARM, it says that the processor is Running, i've got the same problem with the wiggler. When I use the MAJIC, it says "RTCK is stopped or extremely slow. The second board is a custom made board bassed on the LPC2292. It has a mini 10 pin header, with TDO connected, TDI, TCK connected to the header and 3v3 with a 33k resistor, TMS connected to the header, TRST to header and 3v3 by 100k resistor and SRST to the system reset. When I tried the JEENI, because it doen't use the RTCK, I connected to the ground with a 4k7 resistor, with the majic i just connect it. So everything is connected good i believe, and I measured all the inputs to the lpc, and the resets are going up and down propperly, tck gets there, and there goes data in, but there is nothing comming out. I tried to upload a program that implicit sets PINSEL2 to DEBUG, but it didn't help. I have still the same problems as the first board. What the hell am I doing wrong?
