Pandaboard with LCD power supply and initial code transport

Hello Yuan,

About your questions:

#Q1: Is it possible that I get a 2.8 V output from pandaboard?

If possible,how could I get ?

- NO. It is impossible.

The 1.8V output is sourced by PMIC on the board. See following schematics.

PMIC output:

If you want to use higher voltage than 1.8V you must use VBAT pins on J7 connector.  It also implements a DC/DC boost converter that operates from the “battery” voltage, VBAT, and outputs a 5Vdc output that is capable of sourcing up to 55mA of current.

However you must add external converter to get 2.8V for supplying your LCD module.

#Q2: Which file should I modify?

The modification of MIPI DSI driver is complex. It would be fine to provide us more information about your LCD module and OS which you run on your PandaBoard?!

I suggest you to see in details following guides:

http://processors.wiki.ti.com/index.php/Linux_Core_DSS_User%27s_Guide

http://e2e.ti.com/support/omap/f/849/t/285829.aspx

I would kindly ask you not to duplicate your other existing thread about MIPI DSI.

Best regards,

Yanko

My LCD module : HVGA 320 X 480

One CLK lane and one Data  lane

My pandaboard OS : android 4.2.1(Jelly Bean)

Do you need more information?

Well,

What is producer of your display?

Do you know more about LCD driver IC (chip) for the display?

Do you use the official Android release for OMAP4 - http://www.omappedia.com/wiki/4AJ.2.5P2_OMAP4_Jelly_Bean_Release_Notes

Did you already connect your display to PandaBoard?

Best regards,

Yanko

My driver IC producer is sitronix.

Yes, I have this driver IC's spec.

Do you need it?

If you need,could you give me your mail ?

I will send this for you.

**************************************************

My pandaboard OS install flow from:  http://blog.xuite.net/yang44/omap4460/65296550

I don't connect LCD module and pandaboard.

**********************************************************

I need to send command 11h -->29h from pandaboard to LCD module,so that I can see LCD module have screen.

Yuan,

Yes, it would be fine to send us your display and driver IC datasheets.

I would like to notice you that e2e OMAP forum - Support on this forum is focused on board bring-up and basic start-up questions.  OMAP4 module providers and specialized third party experts are available for product development and advanced application support.

In other words we can support our Android release http://www.omappedia.com/wiki/4AJ.2.5P2_OMAP4_Jelly_Bean_Release_Notes

#Q: I need to send command 11h -->29h from pandaboard to LCD module,so that I can see LCD module have screen.

Probably, for sending this command to your LCD module you must use I2C 2 interface module. Its pins are available on J7 connector - h_I2C2_SCL and h_I2C2_SDA. Those pins are dedicated for Touchscreen Interface Control.

At first I suggest you to check if your Display driver is supported in your Android release.

Best regards,

Yanko

Using driver data sheet: 3704.ST7796S_SPEC_V1.0.pdf

Regarding your reply , I have a question.I can send display data by mipi interface.But I have to send command by I2C interface. Could I send command and display data by only MIPI interface? This driver IC doesn't have I2C interface.Or could pandaboard send command by MCU interface ?

Regarding your suggest, I don't understand why android OS support driver IC or not.I think that pandaboard can send data and command by MIPI interfacce. The panel has screen. Right? THX 

Hello Yuan,

#Q: Could I send command and display data by only MIPI interface? This driver IC doesn't have I2C interface.Or could pandaboard send command by MCU interface ?

-  Your display support SPI interface.

- Yes you can send command from OMAP to display driver through DSI.

#Q: Regarding your suggest, I don't understand why android OS support driver IC or not.I think that pandaboard can send data and command by MIPI interfacce. The panel has screen. Right? THX

- I notice you that TI's Android release might support DSI driver for your display. Yes, Panda board can send command and data by MIPI DSI.

I suggest you to use TI's Android release for Panda board - http://www.omappedia.com/wiki/4AJ.2.5P2_OMAP4_Jelly_Bean_Release_Notes

Then, you must add your display in kernel configurations.

Best regards,

Yanko

Regrading my second question,I download from git.But I can't download what I need.

I key "repo init -u git://git.omapzoom.org/platform/omapmanifest.git -b 27.x -m RLS4AJ.2.5P2_JellyBean.xml" from "http://www.omappedia.com/wiki/4AJ.2.5P2_OMAP4_Jelly_Bean_Release_Notes".

Would you please check that the download point is work ? THX

So, I setup the other flow.

Yuan,

I already pointed you that if you want our e2e support you must use the official OMAP4 Android release:

http://www.omappedia.com/wiki/4AJ.2.5P2_OMAP4_Jelly_Bean_Release_Notes

I saw that you have problems with your host machine configurations.

Please execute following settings:

The following commands will install the correct packages to your server:

sudo apt-get install git-core flex bison gperf libesd0-dev zip gawk ant libwxgtk2.6-dev zlib1g-dev build-essential tofrodos
sudo apt-get install lib32readline5-dev libstdc++6 lib32z1 lib32z1-dev ia32-libs g++-multilib libx11-dev libncurses5-dev uboot-mkimage

Install Java SE 6 JDK from Oracle.

http://www.oracle.com/technetwork/java/javase/downloads/index.html

Install repo tool:

mkdir ~/bin -p
sudo apt-get install curl
curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo
chmod a+x ~/bin/repo
export PATH=~/bin:$PATH

If you do not have sudo rights to your machine, contact your System Administrator for assistance.

Please see your .gitconfig file, available in your home.

Add following in it:

        gitproxy = /home/<user>/bin/git-proxy.sh for omapzoom.org
        gitproxy = /home/<user>/bin/git-proxy.sh for git.omapzoom.org
        gitproxy = /home/<user>/bin/git-proxy.sh for review.omapzoom.org

Check your proxy settings.

Best regards,

Yanko
