30 / 99 page ![]() Connecting to the board AN4989 30/99 DocID030181 Rev 2 Figure 17. SWD pins PA13 and PA14 in Reserved but inactive state under STM32CubeMX Figure 18. SWD pins PA13 and PA14 in Active State under STM32CubeMX All three states are functional from SWD connection point of view. It is anyway recommended to explicitly activate the SWD pins by selecting “Serial Wire” or “Trace Asynchronous SW” (together with SWO. Refer to Section 7.3 on page 61). This is the only way by which STM32CubeMX protects the I/O from being selected for another use during the configuration process by highlighting the conflict to the user. JTAG is not available on Nucleo and Discovery boards. On EVAL boards, it is available through a dedicated 20-pin connector. Nevertheless, in STM32CubeMX, SWD remains the default and preferred debug port. For this reason, extra JTAG pins are not reserved. It is then strongly advised to explicitly enable the desired JTAG configuration. |
