I am working on a project with a custom board I developed carrying an LPC1313. Due to space constraints, I am programming it over only SWDIO and SWCLK with ground being routed separately and needing to be at least ~1ft long. Unless I connect a short ground line from the LPC-LINK to the PCB, I get a variety of errors during program that I attribute to communication errors. Though there are probably ways I could redesign the PCB to deal with this, I am looking for solutions for the current system. One potential option is to reduce the bitrate that SWD runs at. Is there a way to configure this?
