SPRUI97E May 2017 – September 2025 AM5716 , AM5718
The AM571x IDK EVM is available with an optional LCD panel that also has a capacitive touch overlay. The video output driven for the LCD panel from the AM5718 processor is on VOUT1. A MIPI bridge device from Toshiba, TC358778, is implemented to convert from the 24-bit RGB presented on the VOUT1 pins to serial MIPI RGB streams. The LCD panel is shipped with FPC cables that plug into J16 for the MIPI video and into J17 for the touchscreen controller. Both the MIPI bridge device and the touchscreen controller are connected to the IND_I2C chain from processor port I2C1.
The LCD output functionality is available only when the AM571x IDK EVM is configured for the 4-port Ethernet mode. When the AM571x IDK EVM is configured for the 6-port Ethernet mode, the LCD output is no longer available since the same pins on the AM5718 device are used for both functions.
Installing a shunt on header J51 that shorts these pins together enables 4-port Ethernet mode. Removing the shunt from these pins enables 6-port Ethernet mode.
