We have observed from time to time that we need to restart the DLPC3478 chip because it stops responding to I2C commands. This has been difficult to reproduce, especially on the TI devkit, but now we have a way of reproducing on the TI devkit. If we just run the ReadValidateExposureTime() command in a loop it will stop responding after some hours. The python API responds back with "Read Validate Exposure Time Command Execution Failed". Please see attached python example.
