Hi Team,
I am using iMXRT1160 for my project.
1. In HAB-Open board, I tried to connect the board using jlink without writing the password on JTAG specific register, I can read and connect the target through JTAG successfully.
2. In HAB-Closed, I have written the 128-bit character as JTAG password on JTAG_RESP [127:0] in order to Secure JTAG debug mode and locked the JTAG_RESP_RLOCK [3:0] efuse register.
To run and read secure JTAG mode successfully, I used to follow the reference Secure JTAG for i.MXRT1170 (nxp.com).
Then, I did the following procedure that was given in the AN13133.pdf
jlink.exe -JLinkScriptFile NXP_RT1160_SecureJTAG.JlinkScript -device CORTEX-M7 -if JTAG -speed 30 -autoconnect 1 -JTAGConf -1, -1
I could not connect the target board after doing the steps referred in AN13133.pdf
Now, I would like to know how i can set and change the JTAG_MOD pin settings and the JTAG_MOD pin is connected with R403 (10k) resistor by default the pin is set with 0 in board. Should I need to solder the pin?
Kindly let me know, is there any procedure to follow?
Thanks & Regards,

Hi...
I have given the steps in last queries that was completely wrong and followed for i. MXRT1060. forSecure JTAG Mode.
For i. MXRT1160 Secure JTAG Mode, I have written the 128-bit character as JTAG password on JTAG_RESP [127:0] in order to Secure JTAG debug mode and locked the JTAG_RESP_RLOCK [3:0] efuse register.
To run and read secure JTAG mode successfully, I used to follow the reference Secure JTAG for i.MXRT1170 (nxp.com). in which JTAG_MOD pin settings has not been mentioned in the script and Default JTAG_MOD logic is 0 whenever we check the JTAG_MOD pin.
Then, I did the following procedure that was given in the AN13133.pdf and I have provided the secure jtag script that i followed.
int InitTarget(void) {
int v;
int Key0;
int Key1;
int Key2;
int Key3;
// Secure response stored @ [0xcb0-0xce0] in eFUSE region (OTP memory)
Key0 = 0x12345678;
Key1 = 0x12345678;
Key2 = 0x12345678;
Key3 = 0x12345678;
JLINK_CORESIGHT_Configure("IRPre=0;DRPre=0;IRPost=0;DRPost=0;IRLenDevice=4");
CPU = CORTEX_M7;
JLINK_SYS_Sleep(100);
JLINK_JTAG_WriteIR(0x9); // Output Challenge instruction 0b1001
// Readback Challenge, Shift 64 dummy bits on TDI, receive Challenge bits on TDO
JLINK_JTAG_StartDR();
JLINK_JTAG_WriteDRCont(0xffffffff, 32); // 32-bit dummy write on TDI / read 32 bits on TDO
v = JLINK_JTAG_GetU32(0);
JLINK_SYS_Report1("Challenge UUID0:", v);
JLINK_JTAG_WriteDREnd(0xffffffff, 32);
v = JLINK_JTAG_GetU32(0);
JLINK_SYS_Report1("Challenge UUID1:", v);
JLINK_JTAG_WriteIR(0x1); // Input Response instruction 0b0001
JLINK_JTAG_StartDR();
JLINK_JTAG_WriteDRCont(Key0, 32);
JLINK_JTAG_WriteDRCont(Key1, 32);
JLINK_JTAG_WriteDRCont(Key2, 32);
JLINK_JTAG_WriteDREnd(Key3, 32);
return 0;
}
jlink.exe -JLinkScriptFile NXP_RT1160_SecureJTAG.JlinkScript -device CORTEX-M7 -if JTAG -speed 30 -autoconnect 1 -JTAGConf -1, -1
I can't connect the target properly after doing the above-mentioned steps and I attached the result below.
How to connect the target board for i. MXRT1160 Secure JTAG Mode?
Kindly let me know is there any procedure need to follow.
