Hi, i'm using the ULINK to program an ARM based developent board from Texas Instruments (TMDS-FET470R1B1M). The Keil Microvision shows the ULINK Serial Number but doesn't found it in the "JTAG Device Chain" (TD0) and when I try to program the flash it shows a error message "no ARM device foung in JTAG chain".
Has anyone ever had this problem or knows how to solve it ?
Thank You.
I had the same symptoms. My PCB was missing some 10k pullup and pulldown resistors on the JTAG lines to the target. I copied the Keil schematic example on their website and that fixed the problem.
