Hi,

When I try to insert the hdmi module, it fails with following log

Prabhakar,

Are you using EZSDK filesystem or just PSP + arago fs?

If EZSDK full feature fs, the hdmi module loaded by the load-hd-firmware.sh script:

echo "Loading HDVICP2 Firmware"
        prcm_config_app s
        modprobe syslink
        until [[ -e /dev/syslinkipc_ProcMgr && -e /dev/syslinkipc_ClientNotifyMgr ]]
        do
            sleep 0.5
        done
        firmware_loader $HDVICP2_ID /usr/share/ti/ti-media-controller-utils/dm814x_hdvicp.xem3 start
        echo "Loading HDVPSS Firmware"
        firmware_loader $HDVPSS_ID /usr/share/ti/ti-media-controller-utils/dm814x_hdvpss.xem3 start
        modprobe vpss sbufaddr=0xBFB00000 mode=hdmi:1080p-60 i2c_mode=1
        modprobe ti81xxfb vram=0:24M,1:16M,2:6M
        configure_lcd
        modprobe ti81xxhdmi
        modprobe tlc59108

If pure PSP:

Load VPSS and HDMI Module

$ insmod syslink.ko
$ ./slaveloader startup VPSS-M3 ti816x_hdvpss.xem3 
$ insmode vpss.ko 
$ insmod ti81xxfb.ko
$ insmod ti81xxvo.ko
$ insmod ti81xxhdmi.ko

Typical Sequence

Load the Modules in the following order.

Load VPSS module, (This module configures and starts the display 0 VENC in 1080p-60 mode.) :

 insmod vpss.ko

Load fbdev module :

 insmod ti81xxfb.ko

Load on-chip HDMI module :

 insmod ti81xxhdmi.ko
