Hello Support !
I'm trying to use the boundary-scan on the DAC39J84, but once the TAP set ins sample mode, the DAC stop sending data (see logic analyzer result below).
I'm able the set the tap in BYPASS or IDCODE mode and get the right IDCODE value.
I'm using the .bsdl file I found on texas instrument forum for the DAC38J84 and simply rename the part name.
I test the JTAG on multiple board equipped with DAC39J84, repeating the same issue.
This post mention DAC89J84 use IEEE1500.
Is it possible to do boundary-scan on DAC39J84 using IEEE1149.1 ?
Is it normal I can't set the TAP in SAMPLE mode ?
Is the .BSDL file correct ?
Thanks for the help.
