Hi SIr
We used Processor-SDK-04.01.00.06 for development and used LIDD setting to send data/command to RA8875 chip for display.
1. in u-boot, it can display normally.
2. in kernel ->QT stage , we have integrated RA8875 TFT driver in the kerenl and can show rootfs data in LCD via FB0.
if we execute "/etc/init.d/matrix-gui-2.0 start" and then execute matrix_browser -qws http://localhost:80, the error message showed as below
Could not set DRM(4) CRTC(24) mode! (Permission denied)
Do you have any suggestion for it ?

Hi Yimin,
Thank you for your patience. Can you try running the script below, and check if anything looks out of place:
#!/bin/sh echo "WSEGL settings" cat /etc/powervr.ini echo "------" echo "ARM CPU information" cat /proc/cpuinfo echo "------" echo "SGX driver information" cat /proc/pvr/version echo "------" echo "Framebuffer settings" fbset -i echo "------" echo "Rotation settings" cat /sys/class/graphics/fb0/rotate echo "------" echo "Kernel Module information" lsmod echo "------" echo "Boot settings" cat /proc/cmdline echo "------" echo "Linux Kernel version" uname -a
Regards,
Mike
