We are starting to get ready for production and will have 24 board on each panel. It would be great to be able to "chain" 4 to 6 nRF52840's together using the multi-drop protocol for programming and initial board test.
Does the nRF52840 support ARM's SW-DP multidrop protocol options?
I can not find the previous white-paper for programming the nRF52's, is there a new one?

Hello,
I can not find the previous white-paper for programming the nRF52's, is there a new one?
Do you mean nWP027 - nRF52832 Production Programming? This can be found under White Papers in our Infocenter
According to the nRF52840 Debug and Trace chapter:
The debug access port (DAP) implements a standard ARM
CoreSight
serial wire debug port (SW-DP), which implements the serial wire debug protocol (SWD).
It does not support multidrop from what I can see.
Kind regards,
Øyvind
