Serial wire flash writing

[wsglee]

Hello,

I'm planning serial wire flash writing from custom board gpio to nRF52840 serial wire.

nRF52840 SWDIO/SWCLK/NRST are connected to a custom board GPIOs.

Is there any material I can refer to?

Hi,

Is there any material I can refer to?

 Indeed there is :).  See our whitepaper on " nRF52832 Production programming" and this older blog about SWD for nRF52832.
