Issue with Enabling DCU/HDMI on LS1021A Kernel

khandavalli · ‎05-29-2015

Hello,

I'm working on LayerScape LS1021ATWR facing difficulties in enabling the DCU/HDMI on the LS1 kernel. Following is my configuration info

SDK: v1.7

Kernel: v3.12.19

U-boot: Bank0: Normal u-boot

Bank1: Lpuart u-boot

RCW: Bank0: RSR_PPS_70/rcw_1000.bin

Bank1: rcw_1000_dcu.bin

Switch Settings: SW2: 10000111

SW3: 01101001

Jumper Settings: J19-20: 1-2

Filesystem: Graphical image

bootargs=console=ttyLP0,115200 hdmi root=/dev/nfs nfspath=<path to rootfs> rootwait rw ip=dhcp video="fslfb:640x480-32@60,monitor=hdmi"

I'm trying to boot the kernel from the bank1 where in u-boot is configured for lpuart and rcw is also for dcu (I have also verified with rcw_1000_lpuart.bin in bank1). Im booting via NFS, since booting via sdcard while testing hangs the board. I wanted to know if i'm missing something in the bootargs, I have verified that all the modules required for dcu are compiled built-in and required dts information is also present. could you please help in enabling the HDMI in kernel while booting from bank1.

Regards,

Arun Khandavalli.

Hello khandavalli,

First please check whether u-boot can be displayed with HDMI.

=> setenv video-mode "fslfb:640x480-32@60,monitor=hdmi"

=> save

=> reset

build kernel images with enable below kernel option:

set bootargs in uboot:

setenv console 'ttyLP0,115200 hdmi res=640x480'

boot up kernel then kill terminal and restart terminal

root@ls1021atwr:~# killall matchbox-window-manager

root@ls1021atwr:~# xinit /etc/X11/Xsession

Please let me know, if your problem remain.

Have a great day,

Hello Yiping,

At the u-boot level with lpuart and rcw-dcu in bank1 im able to get the hdmi display in the u-boot with 640x480 resolution.

My problem is during the kernel booting, all the related kernel configuration parameters I have enabled:

1) CONFIG_ FB_FSL_SII902X = y

2) CONFIG_FB_FSL_DCU = y

3) CONFIG_LOGO = y

4) CONFIG_LOGO_LINUX_MONO = y

5) CONFIG_LOGO_LINUX_CL UT224 =y

6) CONFIG_LOGO_LINUX_CLUT224 = y

7) CONFIG_FRAMEBUFFER_CONSOLE = y

I have set the bootargs for booting as suggested:

=> pri bootargs

I have following points to add:

1) SII9022 DVI/HDMI Interface Chip has got successfully probed, it is reading the EDID and we can see the prints from the driver in the kernel log.

2) I have seen some warning messages from fbcore "Unimplemented SVD " which when i digged through the code seem related to the CESA. Does these warning effect the functionality of the HDMI?

3) I have also seen few waning/errors from the matchbox:

matchbox: Cant find a keycode for keysym 269025056

matchbox: ignoring key shortcut XF86Calendar=!$contacts

matchbox: Cant find a keycode for keysym 2809

matchbox: ignoring key shortcut telephone=!$dates

Is there anything to be added inthe bootargs or enabled in the kernel defconfig?

Hello Reply to khandavalli,

It seems that he message "Unimplemented SVD" is abnormal, we never see it.

The following Kernel boot bootargs is used.

root=/dev/ram0 rw console=ttyLP0,115200 hdmi

The following options are enabled.

CONFIG_ FB_FSL_SII902X

CONFIG_FB_FSL_DCU

CONFIG_LOGO

CONFIG_LOGO_LINUX_MONO

CONFIG_LOGO_LINUX_VGA16

CONFIG_LOGO_LINUX_CLUT224

CONFIG_FRAMEBUFFER_CONSOLE

Have a great day,
Yiping
