Based on Xunwei's 4418 core board_I made a baseboard-problems with QtE interface operation [Copy link]

I made a baseboard myself, using Xunwei's 4418 core board. I removed the I2S and camera drivers from make menuconfig and added the drivers I wrote to configure these pins as input ports. The Qt application wrote a program to read the pin input frequency. And set it to start at boot. Phenomenon: When the machine is turned on, there is no screen calibration operation, and it jumps directly to the main interface. I checked etc and there is no pointercal. The touch screen can be used, but it is not accurate. The qt4.shell is modified according to the latest manual v1.8. I don't know what the reason is. 1. The interface will be distorted after running for a period of time, and the restarted system will have the problem of repeated system restarts. The serial console printout is in the attachment. Is it a freeze? 2. Occasionally, there is another phenomenon, that is, after running for a period of time, the touch screen will be black and the power light will not light up. Is it a power consumption problem? file:///C:\Users\123\Documents\Tencent Files\1486434430\Image\C2C\FS8PWEBA)(DI7CVHAKS]Y5N.jpg
