Dear TI:
This is my display architecture diagram:
Problem: According to the EVM default configuration, the SoC side cannot read the address and register of the EVM device
But I found a way to improve. After the J9 jumper of EVM was pulled out, the above problems were improved a lot.Can TI help explain why?
My SoC side I2c bus connects multiple devices.Each device on the I2c bus on the Soc side is connected with a 2.7k resistor and pulled to 3.3v. Does this affect EVM?
Unplug the jumper of J9, will it have a bad impact on the subsequent I2c communication?
Best Regards,
xinyu
