Rebuilding SYS/BIOS

Hi Meng,

Where did the bits/stdio.h come from? It is not part of the SYS/BIOS install.

Todd

Thank you for your reply, Todd.

I know it's not part of the SYS/BIOS install. But when I rebuild the SYS/BIOS through DOS command prompt window, it will have an error because there is no source file such as "endian.h" and so on.

So I copied those files from Red Hat Enterprise Linux v5.The path is /include.

Is there anything wrong ??

Or what should I do when the error that is no source file happened?

Can you tell me ?

Thanks.

Meng,

The steps to build any operating system are pretty formal. I don't think putting SYS/BIOS files into Red Hat would work either.

What are the exact errors you get when you tried to rebuild SYS/BIOS (as shipped)? Why are you trying to rebuild it anyway?

Todd

Thank you , Todd.

I know it's formal, but I have no idea about it.

When I rebuild the SYS/BIOS , it will have a question as follows:

It told me that it needs some source files. But I didn't find the file.

So in this case, what should I do??

If I want to modify or add functionality, I need to rebuild the SYS/BIOS.

So can you give me some good ideas??

I'll confirm that the instructions in the guide are correct. I'll do this on Monday morning.

Todd

Meng,

When you tried to rebuild SYS/BIOS had you modified any of the code?

Can you attach your biosConfig.bld file?

Are you building on Linux or Windows?

Can you printout your XDCPATH and Parth (e.g. on Command Prompt, type "set").

Todd

Thank you , Todd.

1. When I tried to rebuild SYS/BIOS, I have modified some code.

2. My biosConfig.bld file is as follows:

3. I am building on Windows

4. My XDCPATH is as follows:

set XDCPATH=%XDCPATH%;E:/CCS_5.0.3/ipc_1_22_03_23/packages

Are there any problems??

It looks fine. Were you able to rebuild before you made modifications. I recommend doing this to avoid issues that you might have introduced. Can you type "set" in the command prompt. I'd like to see all your environment variables.

Todd

Thank you, Todd.

Before I made modifications, I didn't rebuild.

When I tried to do this, I also had some questions.

1. When I rebuild, I modified some path in my biosConfig.bld file. This is as follows:

     var rootDirPre = "E:/CCS_5.0.3/ccsv5/tools/compiler";

    Win32.rootDir = "F:/VS2008";

    Win32.vcPath["VC8"].sdkPath = "F:/VS2008/SDK"; 

2. After modification, I rebuild. There is an error as follows:

It told me that it needs some files.

3. My environment variables are as follows:

Are there any problems??

Can you give me some suggestions??

Hi Meng,

I am able to reproduce the error you've been seeing here.

The only thing I change here so far was:

var rootDirPre = "C:/TI/ccsv5/tools/compiler/"; (because I'm using CCS v5.1)

I'll get back to you when I know more.

Meng,

if you aren't planning to use the FatFs (FAT file system) utilities, then you can simply exclude it from being built with SYS/BIOS.

To do this, rename the "package.bld" file within ti/sysbios/fatfs/utils/ to some other name, such as "package.nomak."

This problem has been fixed in the more recent versions of SYS/BIOS.

Thank you , Tom

1. When I only changed the rootDirPre, it told me that the Win32.rootDir is wrong. So I modified it.

   At last, I modified the rootDirPre, Win32.rootDir and Win32.vcPath["VC8"].sdkPath .  After modifying the path, it told me that it's lack of some files.

   So what should I do??

2. If I rename the "package.bld" file, is there any influence on the system?? 

Thank you , Tom.

I rebuild the SYS/BIOS as you said. It had no errors.

And then I used the new package in CCSv5, that means I pointed my project to this rebuilt under the Products and Repositories tab.

When I debug my project, the CCSv5 was automatically closed.

Why did this problem occur??

Meng

Hi Meng,

I don't know why CCS would have closed or crashed. Does it happen repeatedly?

Did you add your version of BIOS with the "packages" sub-directory and remove the existing version of BIOS?

e.g. C:\mybios\custom_bios_6_31_04_27\packages

Did you perform a "Clean Project" before rebuilding?

Thank you, Tom

This problem happened repeatedly.

Of couse, I added  my new "packages" sub-directory and remove the existing one as follows:

I didn't perform the clean project. Because when I executed the command "xdc clean", it would occur an error as follows:

So what's the problem??
