There is an application, Flash USB Direct Programmer that is part of the SK-FM4-176L-S6E2CC CD contents download (path ..//SK-FM4-176L-S6E2CCA_CDv1.1/Tools/USBDIRECT-V01L11/setup.exe.) The tool communicates with the ROM bootloader through a graphical user interface. The Flash USB Direct Programmer can program, erase, and verify memory contents of the S6E2CC device To invoke the internal ROM boot loader, see the table below for jumper settings. Jumper and Position Pin Number Pin Function J2 closed 85 MD0 – mode pin J3 2-3 position 172 P60 – port to select USB or UART boot method. J4 2-3 position N/A Power board via USB CN3 After all jumpers have been positioned properly, connect a USB cable between CN3 and PC. The ROM bootloader will be invoked when MD0 and P60 are high level through a reset or power on. See Program with USB Direct Programmer and ROM Bootloader for step by step instructions. 3.4 Additional Board Features This section describes the USB device, acceleration sensor, and phototransistor features that are on the SK-FM4-176L-S6E2CC starter kit board. 3.4.1 USB Connector CN3 is a micro-B connector that interfaces to the USB0 peripheral of the S6E2CC device to enable development of USB device applications.
