Accessing CORTEX M0+ via APB

Post by sandeep.babu » Thu Jul 12, 2018 10:36 pm


We are using custom SoC design where the CORTEX M0+ cores are connected to the DAPLITE via APB2AHB Bridge. We are able to access ROM tables via APB but we are unable to access M0+ via APB as the JTAG debuggers (we have an Olimex ARM-USB-OCD-H) by default search for M0+ in AHB bus only. Kindly, advise any technique or methods to connect to M0+ core via APB in the setup mentioned. The JTAG architecture diagram is attached.
