Splet01. nov. 2016 · The datasheet recommends to use a pull-down on the SWCLK while the user manual states that there is an internal pull-up. This leads to higher standby currents due to the two opposite resistors on the SWCLK! 0 Kudos Share Reply 08-13-2024 02:26 AM 3,663 Views hmyoong Contributor III This is my understanding based on all the information … Splet03. dec. 2024 · The RST is not part of SWD interface itself, although it is in the same connector. (SWDIO, SWCLK are required, SWO is optional for tracing); you can debug without reset connected, but then you have to reset via other uc-specific means (or jump back to reset vector, that leaves peripherals not reset).
