OKdo E1

OKdo E1 evaluation board

This article describes specifics for the OKdo E1 evaluation board, with an NXP LPC55S69JBD100 target MCU.

Minimum requirements

• J-Link software V6.80b or later
• Embedded Studio V4.52c (for the example project)
• J-Link V10 or later / J-Trace PRO V1 or later

Preparing for J-Link

To make the OKdo E1 evaluation board work with J-Link, it is required to solder connections to the board.
To use SWD, the following is required:

• As marked in the picture above:
  • Solder a cable in front or behind the resistor R308 (1)(TRGT_SWDIO).
  • Solder a cable in front or behind the resistor R307 (2)(TRGT_SWCLK).
  • Solder a cable to GND (3).
  • Solder a cable to VDD (4).

• Connect the J-Link pins to corresponding cables as listed in the table below:

  J-Link pin	Board connection (as shown in the picture)
  7 (SWDIO)	1 (TRGT_SWDIO)
  9 (SWCLK)	2 (TRGT_SWCLK)
  4 (GND)	3 (GND)
  1 (VTref)	4 (VDD)

  For more information about the J-Link interface please refer to the SEGGER homepage

• Power the board via the DEBUG USB port.
• Verify the Connection with e.g. J-Link Commander. The output should look as follows:
  

Example Project

The following example project was created with the SEGGER Embedded Studio project wizard and runs out-of-the-box on the NXP JN5189-DK006. It is a simple Hello World sample linked into the internal flash.
