For detailed information on using the tools refer to the documentation included in the tool chain installation or visit the website of the tools supplier Programming the IDM 16 The IDM software package includes pre built binaries for each of the example applications If you installed DriverLib to the default installation path of C DriverLib you can find the example applications for the IDM in C DriverLib boards rdk idm The LM Flash Programmer is a free tool for programming Stellaris microcontrollers It can be used in two modes to update the firmware on the IDM All IDM example applications are designed for use with the Stellaris boot loader which supports updating of the main application firmware over Ethernet Alternatively the LM Flash Programmer utility can be used in conjunction with any Stellaris evaluation board to program the IDM The Stellaris evaluation board acts as a USB to JTAG SWD hardware interface and should be used in cases where the boot loader image is not present or where the main application image is not behaving correctly and cannot receive the Ethernet signal telling it to transfer control to the boot loader However in normal operation it is more convenient to program via Ethernet To program example applications into the IDM using the Ethernet based firmware update 1 Install the LM Flash Programmer utility on a Windows PC 2 Ensure that the IDM is connected to the same subnet of your Ethernet as the Window
