Hello!

Could you please advise if the following schematic is recommended for SWD / JTAG adapted for Kinetis MCUs (MKM33):

HardwareDebugConnections - ** Code Red Support Site **  

Or it's better to use another one?

Is it critical to use pull-up and pull-down resistors for SWCLK and SWDIO lines? May the adapter work without them?

 

Thanks,

Alexey
