Part Number: OPT8241-CDK-EVM
Hello,
I just wanted to inform you what happens if you try to update the OPT9221 firmware on the OPT8241 EVM using Windows 10 and the TI EEPROM Programmer.
Software used:
- Windows 10
- VoxelViewer 0.9.6
- Firmware to flash: OPT9221_Fw_0v29
Procedure
- Connect and power the camera
- Start VoxelViewer
- Connects to the camera, streaming works
- Start EEPROM programmer from file menu
- Select device and correct firmware (OPT9221_0v29.tie)
- Click Download
- Wait for the window to show the 'done' message
- Power-cycle the camera
- Result: Chipset led stays off, camera does not stream anymore.
- Repair: Use a Windows 7 PC, follow the exact same procedure, camera works again.
The behavior is reproducable. So, in short:
Situation: Upgrading the TI kit using a Windows 10 PC will invalidate the firmware. (Note: The device can be recovered!)
Effect: The chipset LED does not light up anymore and you won’t get any readings from the depth camera anymore.
Solution: Connect the kit to a Windows 7 PC and use that one to re-flash the firmware. Devices with invalid firmware can be recovered, as long as they still communicate via USB (which is usually the case, as the FX2 firmware remains untouched).
