Problem: Computer will not Recognize the VEX Cortex

1.WasthecorrectstartupsequencefollowedwhenconnectingtheCortextothecomputer?

• StartwiththeCortexTurnedOFF

• ConnecttheCortextothecomputeroverUSB

• TurntheCortexOn

2.Istheconnectedbatterysufcientlycharged?

• Swapinafullychargedbattery

3.DoestheCortexneedtobepowercycled?

• StartwiththeCortexTurnedOFF

• ConnecttheCortextothecomputeroverUSB

• TurntheCortexOn

4.TryanotherUSBportonthecomputer.

• StartwiththeCortexTurnedOFF

• ConnecttheCortextothecomputeroverUSB

• TurntheCortexOn

5.TryputtingtheCortexinto“Bootload”mode

• StartwiththeCortexturnedOFF(butwithabatteryconnected)

• PushandholdCongbuttoninontheCortex.

• AttachtheUSBcablebetweenthePCandCortex.

• WaitfortheRobot,VEXnetandGamelightstoblinkgreen.

• ReleaseCongbutton.

• TurntheCortexON.

• TheninROBOTC,click“Robot”,“DownloadFirmware”,“MasterCPUFirmware”,“StandardFile”.

• AftertheMasterCPUFirmwarenishesdownloading,click“Robot”,“DownloadFirmware”,“ROBOTC

Firmware”,“StandardFile”.

AdditionalNote:ThisstepmaybenecessaryiftheMasterCPUFirmwarewascorruptedand/oronlypartially

downloadedtotheCortex.Alsopossible,ifthewrongrmware(VEXnetJoystick)wasdownloadedtothe

Cortex,thisstepmaybenecessary.
