A simple way to do this is by reading the program counter with SWD debug, you must see and address like 0x2xxxx.</P> <P>Diego</P> <P>&nbsp;</P> <P>&nbsp;</P> <P>&nbsp;</P> Tue, 16 Apr 2024 18:47:44 GMT diego_charles 2024-04-16T18:47:44Z https://community.nxp.com/t5/i-MX-Processors/SEC-tool-Connection-Error/m-p/1848067#M222589 <P>Hii,</P><P>I am trying to use SEC tool for IMXRT1064 but it I am not able to establish the connection properly.</P><P>Please let me know if any changes or settings are required</P> Tue, 16 Apr 2024 11:17:47 GMT https://community.nxp.com/t5/i-MX-Processors/SEC-tool-Connection-Error/m-p/1848067#M222589 Vishwajeetlohar 2024-04-16T11:17:47Z https://community.nxp.com/t5/i-MX-Processors/SEC-tool-Connection-Error/m-p/1848416#M222613 <P>Hi&nbsp;<a href="https://community.nxp.com/t5/user/viewprofilepage/user-id/232292">@Vishwajeetlohar</a>&nbsp;</P> <P>I see that the tool is not being able to establish communication with the RT1064's USB port.
