Have you tried sending one or more SWD line resets before swd_seq_jtag_to_swd instead of plain 0xff's? Also, why not set the frequency to the current adapter_khz value instead of some "low default"? > It would still be valid ADIv5 if we applied this patch to the drivers, > but I suspect making per-target tweaks is a slippery slope of > badness... Yep. I think it's likely the frequency should be set to the user-specified values on all drivers automatically before init. And an appropriate switch or reset sequence should be initiated by the higher levels, not from inside the drivers. Probably if nrf51 works with several line resets before jtag2swd it'd be ok to have it that way for all the targets. -- Be free, use free (http://www.gnu.org/philosophy/free-sw.html) software! mailto:[email protected] ------------------------------------------------------------------------------ Want fast and easy access to all the code in your enterprise?
