I'm looking for some help in launch boundary scan tests (example INSTRUCTION_CAPTURE) in STD 1149.1 of MA2085. In BSDL file there is information, to switch chip in BS mode need first setup compliance pins "(test_enable, reset) (00)". Unfortunately it doesn't work for me. On TDO there is constantly logical "0". Is there any additional sequence that need first run to have access to JTAG interface?
Of course all voltages, clocks are setup correctly because final product works well.
