3D-TOF-CDK-EVM: I have a booting problem in cdk-evm.

Part Number: 3D-TOF-CDK-EVM

I purchased opt8241 and opt9221 and made a circuit. However, when you connect the power supply, the Master LED blinks. Is not it just a matter of updating the two F / Ws after creating the circuit?
Is there anything else you do in the early stages before shipping CDK-EVM?

We use Cypress FX2 as host to convert DVP data to USB bulk endpoint. FX2 needs firmware also. OPT9221 needs firmware.
OPT9221 boots from EEPROM over SPI. Which two firmware were you updating?

thank you for your reply

I want to know how to program the OPT9221 and Cypress FX2 those are not "pre-programmed"

And, our custom board is the duplicated circuit that is same with CDK-EVM,

the power is applied as follows.

## Power Pulse Width is about 40ms and duration is 330ms, peak voltage is 1.6V,

If the OPT9221 and FX2 are not programmed, did you set the voltage to flow in the circuit above?
