Electrosmith Daisy Seed
This article describes specifics for the Electrosmith Daisy Seed evaluation board. The board contains the ST STM32H750IBK6 chip and has an ISSI IS25LP064 64 MBit SPI flash.
QSPI Flash Programming Support
Before continuing with this article, please read the generic article about QSPI flash programming support on STM32H7 devices (STM32H7 (Q)SPI support).
As described in the generic article, the reference flash algorithm is based on the SEGGER Open Flashloader and therefore needs to be added manually using a JLinkDevices.xml file. An example JLinkDevices.xml file as well as pinout used on the Daisy Seed board, is given below. For further information regarding the Open Flashloader and how to use the JLinkDevices.xml file, please refer to the Open Flashloader article, section Using a precompiled Flashloader.
Quad-SPI Interface Pins
The Electrosmith Daisy Seed uses the following port pins to interface the (Q)SPI flash.
