MakingHttpServer Presentation Problems

Hi Bin,

I'll try to reproduce this and get back to you.

Todd

Hi Todd,

Thanks for your help. I am looking forward to your new file.

Many Thanks,

Bin

Hi Todd,

Thanks very much for your kind help and it is very appreciated.

The new file is working absolutely fine as described. I kept on following the steps to enable LFN support and finally I can sucessfully compile it. However, when I tried to input my IP address, I still got the 404 Error. But if I type in "<IP>/greetings.html" or "<IP>/default.html" in my browser, I can get the information stored in the SD card. I am wondering is that correct to get 404 Error again when I only type in my IP address ?

Many Thanks,

Bin

Hi Todd,

There is one more question. In function "AddWebFiles", the "efs_createfile("getTime.cgi", 0, (UINT8 *)&getTime);" is uncommented. Why cannot I see the cgi from the webpage when I input my IP address ?

Kind Regards,

Bin

Do you have index.html file on the SD card?

Regarding the cgi, you should be able to see it if you point your browser to <ip addr>/getTime.cgi.

What browser are you using?

Todd

Hi Todd,

That code is now working ok by adding an index.html file. But another problem occured.

I loaded the demo code example but errors occured when I built it as shown in Figure. I am guessing this is because of the xdc folder had been changed. Are you able to help how to solve this to make both of these two codes working.

Many Thanks,

Bin

Hi Todd,

Thanks very much for your kind help. That solved the problem.

Hi Todd,

I created a project which uses SD card as the web server. My index.html code is stored in the SD card. Before I added any images in my code, the web server was working ok. The problems occured when I added two images into the index.html code (the code added is shown below). These two images are only 24KB and 32KB and are also stored in the SD card. When I typed my IP address into the web browser, "out of memory" message appeared. The screenshot is shown below. I even tried to reduced the images to be 2KB or used only one image, but still not working. Are you able to help ?

Thanks,

Bin

What browser are you using?

Hi Todd,

I tried different browsers, Firefox, Internet Explorer and Chrome. All these browsers are not working, but Internet Explorer worked a couple of times. Also, I attached the screenshot of ROV when problem occurs, it seems like it is the dchild problem.

I am sorry to reply you normally at this time. I am in the UK and this is the time I come to work.

Hi Bin,

When you have things like a picture in a webpage, the browser will send another request to the target. This generates a new socket request. So if you have multiple pictures in a page, these will generate multiple socket connections...which uses more memory. You can refer to http://processors.wiki.ti.com/index.php/TI-RTOS_Networking_Stack_Memory_Usage for more details about the Networking Stack's dynamic memory allocation.

So, you need to increase the size of the heap that the NDK is using.

Todd

Hi Todd,

I followed the instructions of the link you provided to reduce the stack sizes of NDK in "ndk/Global->Scheduling". However, I am not able to find where can I adjust the heap size in ndk/global. Could you please advise this a bit more detailed.

Alternatively, I am thinking about another idea. I converted my "index.html" file into "default.h" file. This "default.h" file is included in my project in the Project Explorer. I can visit the website without SD card by following the first part of your presentation. However, in this case, I am not able to visit my ".txt" file in the SD card. Do you have any solution for my specific application ?

Many Thanks,

Bin

Bin,

The default SYS/BIOS heap's size is controlled by the BIOS.heapSize configuration parameter.

Can you please start a new post for the other question. We prefer to keep the threads short to make searching easier.
