Hi, I've got a problem with JTAG chain in LPC2148. The same problem that has already been described "JTAG communication failure". I've tried flash magic (erase all flash) - didn't work, hyperterminal - didn't work. I can program it through the flash magic without any problem but jtag just doesn't work. I really don't know how because the program which was running was the slightly modified program from nxp to send and receive data through the usb. The only thing I've changed was the size of endpoints and lighting diodes according to the incoming data. I haven't touched pinsel2. Please help:)
Is there anybody who can help with this problem at all?
check your JTAG settings under project options->debug->settings. namely, reduce JTAG clock speed.
I've done it already, all posibilities of speed, none of them worked.
Check the pin P0.31, if you pull them down at reset, JTAG pins disabled.
