MCU Link Pro does not detect the target

prvermas — Thu, 16 Mar 2023 13:09:16 GMT

Dear All,

I need help in trouble shooting an issue regarding the interface of MCU Link pro probe to a target development board based on iMXRT1021 processor,

System configuration:
IDE: MCUXpresso v11.5.0
Target : iMXRT1021 based board with JTAG connector
Flash Tool: MCUXpresso IDE LinkServer ( inc CMSIS-DAP) probe (MCU Link pro)

Problem statement: When trying to load the firmware (.axf) the gui gives an error that target not detected. Tried with both internal power (MCU LINK Pro) as well as external board power supply.

Jtag connection is standard 10 pin(2x5) connector, with JTAG_TMS(2) & JTAG_TRSTB(10) both pulled high to 3V

The logs are as below

Hi @prvermas,

Please look into the following block post by Erich Styger, I'm sure it will prove useful for your inquiry on recovering debug access for your i.MX RT: https://mcuoneclipse.com/2019/01/02/regaining-debug-access-of-nxp-i-mx-rt1064-evk-executing-wfi/

BR,

Edwin.
