However, "short" may mean "really short" - I had signal integrity trouble doing SWD on a STM32 using a busblaster (FT2232 - my old version of the PCB has no series resistors on board), with 15cm cable. Adding series resistors to SWD and SWCLK fixed that. cu Michael ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ OpenOCD-devel mailing list OpenOCD-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/openocd-devel
