How can the Robostix Gumstix (FFUART) connector be used to get a U-Boot prompt?
The Robostix modifications page shows how the robostix can be modifed to provide V_BATT to the gumstix connector, rather than VCC5. Alternatively, wire up the power for the RS-232 level converter to another pin which provides V_BATT (like the UART pins). See the Serial adapters page for a list of adapters than can be used with the robotsix. All of the UART ports on the robostix are 5v logic level serial ports.
