10. Programming, Debugging, & Development
The processing power of the epConnected Vehicle is provided through the Agora module mounted to it.
Programming & debug access to the Agora module for the development of custom applications is available through
the epConnected Vehicle host board. The host board provides both an Arm Cortex SWD header and a TagConnect
footprint for programming & debug use. Alternately, users may remove the Agora from the host board and program
it with a Flidor development board by Embedded Planet. Flidor contains an OpenSDA programming and debug
interface that can support simple drag-and-drop programming of files onto the target device (in this case the target
is the epConnected Vehicle board).
More on Flidor can be found at

Component Interfaces

11.1.

Component Interfaces | Outputs (U5)

For detail on the output component interface, please refer to the section titled External I/O Pinout (J6).
11.2.

Component Interfaces | GPIO Expander (U6)

The GPIO expander component U6 is an MCP23008. It is configured in I
The interrupt line is from the CAN interface (U3) and optionally the I/O expander (U6 through R3). The
expander must be configured as open drain when R3 is populated. The reset, enable, interrupt, and chip select
signals for this device are active-low.
