I only recently joined this mailing list, so I wasn't privy to those conversations. I can't say that I am aware of any problems with CMSIS-DAP that would prevent it from being suitable for real usage. I, personally, used two implementations: one from Keil(can be flashed on KL26Z Freedom boards) and the one found in Atmel's devkits(called EDBG) and didn't have any problems. > I see a lot of activities around this problem from Angus Gratton, Andreas > Fritiofson, Thomas Schmid, Andrey Smirnov, Angus Gratton, Masaki Muranaka and > Paul Fertser. > > What debugger tools do you use guys? > The only standalone SWD adapter that I had access to at the time when I was developing initial flashing driver for nRF51 was ST-Link v2, so that was what I used for that purpose. Usually nRF51 kits/samples come with Segger J-Link Lite and there were number of patches floating around that should add SWD support for the driver(Those patches didn't work for me, but that may be because I was using OSX) > Another candidate is FTDI based debugger. > This morning I tried it with resistor hack. > It’s working for stm32f1x but doesn’t work for nRF51 at all. > I can provide any logs and do tests if anyone can help with this. > > Does anyone has successful experience debugging nrf51 chip with FTDI based > tool? I have an irrational dislike/distrust of all things FTDI so I don't use it very often. Sorry I can't be on much help here.
