QSPI Flash Evaluator

This article explains how to use SEGGER's (Q)SPI Flash Evaluator board.

Prerequisites

In order to start evaluating with the (Q)SPI Flash Evaluator Board, the following materials are needed:

• (Q)SPI Flash Evaluator board.
  • Note: In order to evaluate QSPI programming, board revision A or later is needed (printing on the back says "Rev. A")
• (Q)SPI Flash soldered to the according adapter board
• Micro USB cable
• J-Link or Flasher
• 20-pin ribbon cable
• A machine running Windows, Linux or macOS with the latest version of the J-Link software package installed

Evaluating direct SPI Flash programming

Direct SPI Flash programming refers to programming the SPI Flash directly, without a CPU inbetween. For more information on direct programming, please refer to the following article: SPI Flash - Direct programming.

Evaluating direct programming can be done by following these instructions:

• Determine the Flash's operating voltage and set the evaluator board's SEL 1.8V jumper accordingly.

  

  For 1.8V Flashes, the jumper needs to be closed.

  

  For 3.3V Flashes, the jumper needs to be open.

• Plug the Flash Adapter board into the evaluator board
  • Note: Make sure that the pins of the adapter board correctly line up with the evaluator board's connector.

  

  

• Power the evaluator board using a micro USB cable

  

  When powered up, the evaluator board's "PWR" LED will be lit.

• Connect a J-Link or Flasher to the evaluator board using a 20-pin ribbon cable

  

• Start J-Flash SPI on the host machine that the J-Link or Flasher is connected to.
  Instructions on how to use J-Flash SPI to execute direct SPI Flash programming can be found in the J-Link/ J-Trace User Guide
