AM2634-Q1: Is it possible to enable debug mode in R5 core of HS-SE device?

Sung-IL

Part Number: AM2634-Q1

Dear Champs,

My customer wants to check if it is possible to enable only R5 core when required.

Could you please let me know if there is a way to enable only R5 core when required and permanently disabled in HSM module?

Thanks and Best Regards,

SI.

This is the MySecureSW link - https://software-dl.ti.com/secure/software/sitara-sec/AM263X-RESTRICTED-SECURITY/TIFS_MCU/v08_06/tifs_am263x_08_06_00_05_docs_only/docs/api_guide_am263x/html/HSM_DBG_SRV.html?__gda__=1691670550_8cb28278838d2140429b03486c80ab8d

It is mentioned that R5 debug can be opened by choosing the Privilege Level as DBG_PUBLIC_ENABLE i.e. 2.

This can be done both in SBL certificate to open the debugs via ROM (preferred in development platform) and TIFS-MCU Firmware.

Hi Aakash,

Thanks for immediate response.

Is there any way to disable JTAG only for HSM module permanently?

Thanks and Best Regards,

SI.

Hi SI,

There is no way to disable JTAG just for specific part of system. DIS_JTAG via eFuses is an option which will also disable the JTAG for all the CPUs and debug masters in the system.
