TIDA-010054: PWM_EN pin shared with jtag TDO pin

Part Number: TIDA-010054


The two quadruple bus buffers used in the DAB have an output enable pin connected to pin 58 (gpio-37) of the control

board, this pin is shared with the jtag test data out, therefore we cannot have both functions at the same time.

Is there any other way in this board to debug and at the same time have the buffers enable? (we would like to modify and view variables from code composer studio)

Regards and thanks in advance.

  • Hello,

    To solve this problem please follow the suggestion of the design guide and remove R13 and R30 and short pins 13 and 14 on U1 and U2. Like this the buffers will be enabled constantly and GPIO 37 can be used for JTAG.

    Best regards,
