Cannot provide power to dap bus
WebAnswer. A DAP is: One Debug Port (DP) that provides one or more external pin protocols, such as JTAG or Serial Wire Debug (SWD), for communication with a debugger. One or more Access Ports (APs) that provide access to on-chip buses where debug components and/or memory can be accessed. The Cortex-M0+ provides an optimized DAP … WebThis means, having multiple Cortex-M cores in a DAP requires a separate AHB-AP for each of them. APB-AP This AP type was first introduced with Cortex-A and Cortex-R based MCUs. The APB-AP provides a separate 4 GiB address space which is different from the core address space.

WebIn the working board it seems that the JTAG_RESET signal is high continously, but in non working board RESET signal goes low after some clock pulses. WebIn theory, you can have hundreds of Cortex-M processors connected to the internal debug bus inside the DAP, each via an Access Port (AP) submodule. The DP submodule also provides a power management handshaking interface so that the debug subsystem in a system-on-chip design can be powered down when the debug system is not being used.
