Files

• JLinkDevices.xml: File:ST STM32F746G Disco QSPI JLinkDevicesXML.zip
• Flashloader *.elf: File:ST STM32F746G Disco QSPI ReferenceFlashAlgorithm.zip
• Example Project: File:ST STM32F746G Disco QSPI IAR7407.zip

The example project contains a simple counter loop which is linked into the (Q)SPI flash memory region @ address 0x90000000. The project includes the JLinkDevices.xml file as well as the ST_STM32F446_Reference.elf. It runs out-of-the-box. Please note, that IAR EWARM must at least use the J-Link DLL version V6.01a, which supports the Open Flash Loader.
