Hello, Thanks for your feedback!

I have tried with adapter_khz 5 or jtag_rclk 2, and not better. Since the JTAG is capable of finding the tap/device, doesn't that mean that the communication is working, and thus that the jtag speed is correct? > 2. Try doing "reset halt" from the telnet first. It does reboot the board, but still can't halt the target. Output of the telnet connection: $ telnet localhost 4444 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'.

Make sure your board has the same reset configuration as you pass > to OpenOCD - separate lines of TRST and SRST. From my reading of the schematics, it seems it does, but I'm not an expert. The schematics of the USB A9263 are available at http://www.calao-systems.com/repository/pub/EMBEDDED%20COMPUTERS/USB-A9263-XXX/C02/HARDWARE/SCH-00007-B01.pdf (FTDI 2232 routing is on page one). Any other suggestion?
