Summary: Screen color is blue or red in microwin test

Details:

Run microwin test on bf548-ezkit/bf537-stamp, screen is covered with blue when nano-X applications are running, while it is covered with red on bf527-ezkit.

The place supposed to be white turns out to be blue or red.

Application video_test has no such problem, and 09r1.1 release is OK.

Follow-ups

--- Michael Hennerich 2010-03-18 05:25:04

What version of the BF527-EZKIT are you using?

Please attach kernel and user config files.

--- Vivi Li 2010-03-18 06:12:00

Sorry, config files are attached.

BF548-EZKIT board version is 1.4;

BF527-EZKIT board version is 2.0.

--- Michael Hennerich 2010-03-18 08:22:34

I wonder if microwin/nano-X ever showed a correct picture on the BF527-EZKIT?

--- Vivi Li 2010-03-18 22:33:34

Except for bug 4126, it can show a correct picture.

At least, BF537-STAMP/BF548-EZKIT used to show a completely correct picture.

--- Michael Hennerich 2010-06-18 06:52:17

I double checked -

BF527-EZKIT board version is 2.1 shows correct colors.

Nanowm desktop is blue while nxclock background is white.

The old BF527-EZKIT uses a reversed color format that nano-X doesn't support.

--- Vivi Li 2010-06-25 06:57:20

Hi, Michael

I have a 2.2 board and don't have 2.1 board.

I can see no picture on lcd screen either in u-boot or with video_test in

kernel. Board config is default and I can't see anything wrong. Could you try it

on 2.2 board?

-Vivi

--- Michael Hennerich 2010-06-25 08:25:32

I wonder if you are using:

1) u-boot: bf527-ezkit-v2 board config?

2) uclinux-dist: BF527-EZKIT-V2 board config?

-Michael

--- Vivi Li 2010-06-28 00:05:26

Yeah, I configured u-boot and uclinux-dist on bf527-ezkit-v2, and it didn't

work.

--- Vivi Li 2010-06-28 00:07:47

My config is attached.

--- Michael Hennerich 2010-06-28 03:51:22

How did you set the LCD Mode switches on the BF527-EZKIT V 2.2?

Try:

SW26:

SW26-1: OFF

SW26-2: ON

SW26-3: ON

SW26-4: ON

SW26-5: ON

SW26-6: ON

SW5:

SW5-1: OFF

SW5-2: ON

-Michael

--- Michael Hennerich 2010-06-28 04:02:48

Looking at your config files:

# Frame buffer hardware drivers

CONFIG_FB_BFIN_T350MCQB=m

# CONFIG_FB_BFIN_LQ035Q1 is not set

You are not using the: BF527-EZKIT-V2_defconfig

Please compare the BF527-EZKIT-V2 against your config files.

New EZKIT uses CONFIG_FB_BFIN_LQ035Q1!

Please make sure that you use the right default config files in u-boot and

kernel.

-Michael

--- Vivi Li 2010-06-28 06:47:24

Thank you, Michael. I didn't realize that I used a wrong LCD driver. I'll update

the build script.

It can show image in kernel now.

And Nanowm desktop makes nxclock blue, isn't it a bug of microwin? I remembered

that in our old release, white used to be white instead of blue.

--- Vivi Li 2010-07-01 22:22:10

Attached is my latest image and config for microwin test on 2.2 board.

I can see that the nano-X colors on your image are wrong.

However on my image they look right.

Comparing your microwin config against mine shows that you are

Using a bad config.

Deselect:

CONFIG_USER_MICROWIN_MWPF_PALETTE=y

And select:

CONFIG_USER_MICROWIN_MWPF_TRUECOLOR565=y

Or:

CONFIG_USER_MICROWIN_MWPF_TRUECOLOR888=y

--- Vivi Li 2010-07-05 02:01:22

Yeah, it works now.

Close it.
