Tool/software:
Hello,
For security reasons we want to disable the JTAG interface.
The device tree has a pinmux section for jtag. Will removing that element disable JTAG?
mcu_jtag1_pins_default: mcu-jtag1-default-pins {
pinctrl-single,pins = <
AM62X_MCU_IOPAD(0x0078, PIN_INPUT_PULLUP, 0) /* (E12) EMU0 */
AM62X_MCU_IOPAD(0x007c, PIN_INPUT_PULLUP, 0) /* (C11) EMU1 */
AM62X_MCU_IOPAD(0x0064, PIN_INPUT_PULLUP, 0) /* (A10) TCK */
AM62X_MCU_IOPAD(0x006c, PIN_INPUT_PULLUP, 0) /* (A11) TDI */
AM62X_MCU_IOPAD(0x0070, PIN_OUTPUT_PULLUP, 0) /* (D12) TDO */
AM62X_MCU_IOPAD(0x0074, PIN_INPUT_PULLUP, 0) /* (B11) TMS */
AM62X_MCU_IOPAD(0x0068, PIN_INPUT_PULLDOWN, 0) /* (B10) TRSTn */
>;
};
Thanks,
Lars
