Other Parts Discussed in Thread: SEGGER
Good day, colleagues,
Customer has questions about AJSM unlock, they couldn’t find information in spna232a and RM44x520 datasheet.
They have question how to unlock JTAG when using non-XDS debuggers (for example, Segger JLink, which has been officially supported in CCS for a long time).
They need information about the AJSM module and how to work with it. Not via CCS, they use the TI port of gcc as a separate tool. They would like to understand how to change the JTAG access scripts (Segger JLink debugger) to get access to debugging from the developer's side with active protection in the AJSM module.
The RM44x520 datasheet has section 6.20.6 "Advanced JTAG Security Module" which mentions the "Unlock By Scan" register of the AJSM. They have not seen any description of this register, and how to get access to it when choosing AJSM in the JTAG. Could you provide this information?
Thank you,
Daria
