The following devices have specific programming requirements or procedures:
| Device | Description |
|---|---|
| nRF91 Series DK | To program the nRF91 Series DK, see Programming nRF91 Series DK firmware. |
| Nordic Thingy:91 X | To program Nordic Thingy:91 X, see Programming Nordic Thingy prototyping platforms. |
| Nordic Thingy:91 | To program Nordic Thingy:91, see Programming Nordic Thingy prototyping platforms. |
| Nordic Thingy:53 | To program Nordic Thingy:53, see Programming Nordic Thingy prototyping platforms. |
| Nordic Thingy:52 | Nordic Thingy:52 can be programmed using the general programming procedure, but only through J-Link and a 10-pin programming cable. |
| nRF52840 Dongle | To program the nRF52840 Dongle, see Programming the nRF52840 Dongle. |
| Custom board | When programming a custom board with a supported chip, use the general programming procedure, but make sure that the J-Link version is compatible with the relevant Arm® CPU. For example, an nRF52 Series DK cannot be used to program a Nordic Thingy:91 since the J-Link on an nRF52 Series DK does not support the programming of the Arm Cortex®-M33 CPU of Nordic Thingy:91. |
