/dev/fb/0 cannot use by NAND's /etc

Yoshiki Komatsudaira

Dear Sir,

I'm using DM355EVM and dvsdk_1_30_00_40.

I can't use /dev/fb/0 (OSD plane) if the EVM boot from NAND flash.

I can use it using NFS root filesystem.

The related bootargs option is below.

>video=dm355fb:vid0=640x480x16,2500K:vid1=640x480x16,2500K:osd0=640x480x16,2400K

I tried copying NFS's /etc to NAND's /etc.

Then, I can use OSD even if booting from NAND flash.

Where of /etc is the difference?

Best regards,

Yoshiki Komatsudaira.

Dear Sir,

I understood.

When boot from NAND, "interface" in /etc/rc.d/rc3.d/S88demo runs.

Now I'm setting bootargs 'davinci_enc_mngr.ch0_output=LCD' (sorry, there wasn't this information).

"interface" sets the lines of /dev/fb/0 to 0 because the 'ch0_output' isn't 'NTSC' nor 'PAL'.

I can re-enable /dev/fb/0 by 'fbset -xres 640 -yres 480 -vxres 640 -vyres 480'.

Sorry for my poor skill...

Best regards,

Yoshiki Komatsudaira.
