How to port a web server on AM335x starter kit

Hi Ivan,

Here are a couple of useful links:

http://processors.wiki.ti.com/index.php/Sitara_AM335x_Portal - this is the wiki portal for AM335X. From here you can find most of the available wiki documents.

http://www.ti.com/lsds/ti/arm/training/OLT312000.page - links to different Linux training sessions.

Hi Biser:

                   Thank you. I knew those pages u provided, and i also looked this link http://processors.wiki.ti.com/index.php/Matrix_Users_Guide#Examples , I have a problem is how to change the default matrix layout to my own webpage, i didn't find any document said about it. 

I'm afraid I don't understand what you want to do.

I don't know can this work, but i have this requirement. My requirement is the user can type a IP and my device can responds a web page to the user, but now I tried it, the device always respond the default matrix layout as we see on the LCD.

Do you mean display a web page on the LCD, or respond over Ethernet?

Respond over Ethernet. I want the user key the IP of device and he can see the web page directly, he doesn't need to select the icon on the matrix.

In this case you will need to install and start a web server application for Linux, that will send the web page over Ethernet when requested. You don't need the Matrix GUI at all.

Um....., so i need to close the matrix service and install another web server application?? i am curious of what usage that will use matrix over ethernet, if user can get matrix GUI over ethernet?? Can you recommend any web server application for me, thank you. 

Hi Biser:

                         Thank you, I resolve this problem temporarily, i used "BOA" to establish my web server, though this project has long time not to update.The link is http://www.boa.org/

Furthermore, because my custom board doesn't have a SDcard slot, can i connect eMMC(4G, 4.5.1) to MMC1 directly based on AM335x SK and connect WLAN to MMC0??

Yes, you can see the Beaglebone Black schematic for reference (http://elinux.org/Beagleboard:BeagleBoneBlack#Hardware_Files ).

Do I need to change something, just connect mmc0 to WLAN?? Because i see MMC have three different commands: (1)MMC(2)SD(3)SDIO, and WLAN receive SDIO command. Or MMC driver will handle this?

The MMC driver should handle it.

So I don't need to write another driver or code, just use the driver that is compiled from linux source code.

Yes. This is the wiki for the SDK 7.0 MMC driver: http://processors.wiki.ti.com/index.php/Linux_Core_MMC/SD_User's_Guide As you will see it supports SDIO.

Um....i am a little curious that how MMC module know the connected device is eMMC, SD or SDIO??? And I saw the driver support 8-bit transfer for eMMC, does it mean I can connect 8-wire to the eMMC module, not 4-wire.

I strongly recommend that you connect all 8 data lines to the eMMC. As for recognition of device, this is achieved by commands over the interface as per the MMC/SD specs.

Thank you, I got it:: ).

Hi Biser:

                    If I only connect 4 wire(eMMC) to mmc1, can it work?? Because i see AM335x SK schematic, the rest 4 pins are connecting to LEDs . I still don't find the dts file i need to modify for pinmux or do you know what file i need to modify. I found a file named "am335x-evmsk.dts" in <SDK7.0>/arch/arm/boot/dts, do this file I want? But i can't find MMC1_D0~MMC1_D3 definition inside.

You can copy the necessary part from the Beaglebone Black dts file. I'm not a Linux expert so I cannot help on this.

In the worst case, if i only connect 4 wire data of eMMC to MMC1 of AM3358, can it work??

I cannot say for SDK 7.0.
