Please check page 6 in the attached doc, " Program 0x1 in the eFuse DAP_SJC_SWD_SEL to switch the DAP to the JTAG mode", but if Program 0x0 in the eFuse DAP_SJC_SWD_SEL to switch the DAP to the SWD modedoes i.MXRT10xx support sucure JTAG mode in this case?

And, page 8 "Download and edit the file J-Link script file named “NXP_RT1052_SecureJTAG.JlinkScript", it also said "The script file can be received from NXP upon request", is it "4.2 Example of SEGGER J-link Secure JTAG unlock script"?

Thanks a lot!

Hello,

>>does i.MXRT10xx support sucure JTAG mode in this case?

It should can't.

>>Download and edit the file J-Link script file named “NXP_RT1052_SecureJTAG.JlinkScript", it also said "The script file can be received from NXP upon request", is it "4.2 Example of SEGGER J-link Secure JTAG unlock script"?

I am checking it with the related team for how to receive “NXP_RT1052_SecureJTAG.JlinkScript", I will forward the information for you if have any update.
