TMS320F28335: error #10008-D: cannot find file, even when the linker path is correct

Hi John,

I am guessing the application is not using any functions or data from this library and hence it is not included in the linking stage. The cmd file is trying to place the sections from this library to a specific memory, but it is unable to do so, since it is not present.

Can you confirm that the library contents are being used in the project?

Veena

Hi Veena,

No the functions are used, they are copied into RAM and ran from there. Here is the lines assigning the memory in the command file. This is where I am getting the error saying that the file can't be opened. In the linker file. I checked the path on just the file as well and there should be no issue.

 Then in the main these functions are copied into RAM and called using the Memory location allocated in RAM.

I am not 100% sure why this was all done this way. I have never worked on this project before this. This is a bootloader, I do know that there are functions ran out of RAM on the application due to speed.

Hi John,

The code you shared is just copying the used sections in the lib from Flash to RAM.

But, are the functions in the library being invoked in the application? The library will be included in the linking stage only if the functions in it are invoked in application

Also, I see that the library is in the folder C:ti\lib. But I do dot see this path in the --search_path. Can you try adding the folder C:\ti\;ib in --search_path. IN this case, you can just put the library name alone(without path) under --library.

Hi Veena,

They are being invoked from RAM yes. The linker seems to be failing to find the file this is directly taken from the example in cmd file in the driver. I stumbled upon this thread for another device. Is it possible that I require the source as well. https://e2e.ti.com/support/microcontrollers/c2000-microcontrollers-group/c2000/f/c2000-microcontrollers-forum/170158/how-to-copy-the-f2803x-flash-api-to-ram

The library is located in the control suite. I added that second file in an attempt to get it working the library is also in the project folder I have added it to a number of places to try and get this to work all with the path correct in the search path.

Thanks

Hi John,

I am repeating, the memcpy function is only copying the "used" functions from the Flash to RAM. Are you invoking any functions from the library in the application? Like Flash_Erase(..), Flash_Program(..) etc

Have you added the library path in the --search_path list under Linker options?

Regards,

Veena

Yes, it is a bootloader we are erasing and programing flash. Yes the path is in the linker search path to the library file.

Hi Veena,

Do you have any ither suggestios? Did you look at the other post that I sent you.
