Openocd gives Unsupported DTM version error

I built the riscv toolchain from https://github.com/riscv/riscv-gnu-toolchain master branch using --enable-multilib --with-arch=rv64imac --with-abi=lp64 configure option.

I built the freedom with default Arty for 35T FPGA board and the mcs file was generated and programmed on Arty 35T board using vivado 2019.2 successfully.

When i reset (or reconnect the USB), i am able to see the LD4, LD5, LD6 light up.
When i press the BTN3, the LD6 is off
When i press the RESET button, the LD4 is off.
Hope the programming is done correctly.
However i am unable to see any sifive logo on the miniterm of /dev/ttyUSB1 even after pressing RESET or reconnecting the USB.
Nothing is displaying on the miniterm.

In freedom-e-sdk, when after compiling using “make PROGRAM=sifive-welcome TARGET=freedom-e310-arty software”, i tried to upload using “make PROGRAM=sifive-welcome TARGET=freedom-e310-arty upload” command. I am getting the following error

(since i am using the arty 35T onboard USB-JTAG FTDI interface itself[i don’t have the Olimex JTAG adapter], i changed “set connection tunnel” in bsp/freedom-e310-arty/openocd.cfg)
