arm Cortex series (JTAG/SWD)
This section describes the specifications for connecting a CPU with a core such as Cortex-M7 or Cortex-A9 to FP-40.
The Cortex core has a dedicated debugging function called DAP. FP-40 uses this debugging function to control the CPU
to write to flash memory. SWD or JTAG is used for communication with t h e D A P. SWD is an ARM proprietary
specification that extends JTAG and uses only the TMS and TCK signals of JTAG. Also, when using JTAG, the
TRST signal may be required, or special processing may be required to use debugging functions. Please be
sure to check the CPU manual before use. This technical document describes general interface specifications.
