Programming SigCell

To program a SigCell, you will need the following:

• SigCell
• Segger J-Link

• 20-Pin to TC2030-IDC Adapter for Cortex: ARM20-CTX from tag-connect.com

• TC2030-IDC-NL "No Legs" 6-pin Plug-of-Nails™ from tag-connect.com
• Retaining CLIP board: TC2030-CLIP from tag-connect.com
• nRF Connect for Desktop

NOTE: tag-connect.com supplies all the needed adapters, but other sources can be used for the ARM20-CTX

NOTE: Early development kits do not have a cut-out for access to the debugging pads. For these development kits, the -TC should be used such that the pads are accessible on the top of the board.

Setup and Programmer tool

1. Connect SigCell to your computer using the J-Link with the TC2030-IDC adapter, connected to the TC2030-CTX-NL cable. The cable is attached to 6-pin "Bed of nails" on the SigCell, circled in red below. It can be held in place with the TC2030-CLIP on the reverse side.

The pinout of the debug pads matches the pinout recommended by TagConnect as shown below.
