Hi
I finished preparing the nrf52832 board to use ppk and measured it with ppk. I am trying to repair the nrf52832 board. However, I do not understand the contents of ppk document, apply a jumper on P22. Could you explain this in detail?

Hello Hongpal
When you cut the solderbridge SB9 you disconnect the nRF from the power supply of the development kit. The Power Profiling kit, when connected, feeds the nRF with power through connector P20, and measures the current drawn. When the PPK is disconnected you need to have an electrical connection between the pins of P22, this is typically done with a 2.54 mm pitch jumper with metal inside, something like this. This way the nRF is again connected to the DK's power supply.
