Open flash loader installer (for SEGGER J-Link)

This project allows you to create a custom installer for your open flash loader in 3 steps. This allows you to distribute a custom installer that automaticly installs the flash loaders in the correct location without user intervention.

Prerequisites

• Windows (for now)
• Visual studio
• The Microsoft Visual Studio Installer Projects plugin
• J-link >= V7.80
• Open flash loader executable (can be created using the OFL template)

Create a flash loader xml file

SEGGER J-Link uses xml files to add support for external loaders. The xml file configures the follwing:

• The target Microcontroller for the loader
• The address the memory is located
• What executable file to load
• The name it shows up as in the J-Link software

Example xml file for the LPC1756 is25lq040b open flash loader.

<DataBase>
    <Device>
        <ChipInfo Vendor="NXP" Name="LPC1756" />
        <FlashBankInfo Name="NOR Flash" BaseAddr="0xA0000000">
            <LoaderInfo Name="SPI flash loader" MaxSize="0x01000000" Loader="flash_loader.elf" LoaderType="FLASH_ALGO_TYPE_OPEN" />
        </FlashBankInfo>
    </Device>
</DataBase>
