Hi
I bought the board OM5578 and a Raspberry Pi 3 Model B, I downloaded "OM5578-PN7150S_Rpi_Linux_demo_v1.2" image. But the raspberry didn't boot, the monitor shown a thunder and a red led on the rasperry blinked (power not enough) I'm using a power supply 5Vdc 2.5A. If I install the RASPBIAN image, the raspberry boots normally with same hardware setup (power supply, monitor etc). what is going wrong?
This image can work on Rasp. Pi 2.
I think the issue is due to the I2C pins setting on Pi 3.
You can try to build the new image for this board.
You can refer to this document.
