Programming custom board from eBay

José Pedro

Hello,

I have recently bought a couple of boards from eBay that come with the nRF58232:

https://www.ebay.com/itm/Wireless-Bluetooth-Transceiver-Module-NRF52832-Development-Board-1-7V-to-3-6V/332128757335?epid=851397440&hash=item4d546aa657:g:VUgAAOSwhf1Zm93o

I am wondering on how can I program this board.. I have and FTDI cable, and I tried to use sparkfun's tutorial, which didn't workout..

Any ideas on the right flow? The connection labels are on the pictures provided on the website.

Thanks in advance,
Jose

    The FTDI cable does USB to UART communications and will not work for programming an nRF52832. The nRF uses SWD communications for programming. If you have SWD you can erase the chip and load any code you wish.

    The only way for uart programming to work is if the board has some sort of custom uart bootloader on it. This is not standard.  You would need to ask the board manufacturer specifics about how they configured it.
