OMAP4460 pandaboard ES Ver.B3 DSI command mode setting

hello,

I got some error messages when I use command mode.

omapdss DSI error: DSI CIO error, cio irqstatus 200000

omapdss DSI error: Failed to complete previous l4 transfer

omapdss DSI error: vc(0) busy when trying to config for VP

omapdss DSI error: TE not received for 250ms!

omapdss DSI error: Framedone not received for 250ms!

Could you help me to solve this error?

Which setting or code do I need to build in source code?

I just want to send LCD module initial code(OK) and frame data( not OK ; OS give).

And I find out that dsi_update_screen_dispc's datas are zeros.

Including w, h, bytespp, bytespl, bytespf, total_len, packet_payload, packet_len.

PS: bytespp = dssdev->ctrl.pixel_size / 8; this code doesn't work. WHY?
