attempting to make MMC/SD card project, can't link

I’m not sure which MMC/SD FAT example you are using, but from the error message it seems that you need to select an “IPC” product in the project properties (the ti.sdo.utils package is in the IPC product).  

If you right click on the project, select properties, general, and then click on the RTSC tab you should see something similar to the following.  



I'm thinking that there is no checked box for an Inter-processor Communication product install, but if you select one of the IPC products, clean and rebuild the project then this error will go away…

Hi Cobsonchael,

As per the error log, it looks like you are using the BIOS PSP 03.00.01.00, am i right?

Are you trying to build the example mmcsd application placed in the path "biospsp_03_00_01_00\drivers\examples\evm6748\mmcsd_fatfs"?  If yes, then, please check the "biospsp_03_00_01_00\makerules\env.mk" file for the appropriate path for all the tools (especially ipc_PATH). And also refer the userguide (C6748_BIOSPSP_Userguide.pdf) section 1.5 for all the environment variables to be set.

well using the IPC made that error go away, but i now have all sorts of linking errors for routines that i thought would be included in the PSP drivers. below is a list of functions that are not linking in.

i am using my own project for this because there are no MMC/SD projects.  there are 2 .c files that would make up a project but it does not include a .project file so i had to make my own project and add in the C files. however, when i open up the ONLY project that comes with the psp drivers (the i2c project)  and that hasd linking errors as well.  this makes me think that i am missing something. either some library or an include path.  i already set up the UTILS_INSTALL_DIR, EXTERNAL_SW_ROOT, and INTERNAL_SW_ROOT. i didn't see anything else i am supposed set.

i guess i must have missed that file (that or i am not used to looking for media files when i look for documentation).  that did fill in the blanks for my linking errors.

it does, now, provide me with additional questions.

1) what is the point of installing the EDMA module, the PSP module, if you have to go out and point to the repository manually anyway? in the video they had those modules installed, but instead of just checking the box they had to manually add the repositories.  what is the point of the module if you don't use them like they seem to be meant to be used?

2) WHY are the drivers not a module you can select the RTSC check box? why do i have to add every single set of driver library myself? why is this a manual thing?  this has to be the least intuitive part of this process, even outside of the fact that the drivers are in a spot you absolutely need the documentation to find and know which files you want.  i swear there are more "driver" folders than you can shake a stick at.  i don't understand why the drivers are not considered a module and we can't just look into the "Available Products" box and select "Use XXXX" to use those drivers.  you claim you want to make this an easy experience but this has been a pain since i have started this task.

Yes, i agree with your concern. We had this RTSC support earlier with all the driver supporting IDriver model. To support this each module (driver) needs to have its own .xdc file and .xs file. As per the user feedback, we realized that the user is more familiar in modifying/understanding the .h/.c file instead of .xdc/.xs file.

Note: The xdc command would convert the .xdc to .h file.

And also, gmake is more generic than the xdc command.

So, considering the above concerns from the end user, we decided to use the IOM driver model along with the gmake support.

Any way, thanks for your valuable feeedback.
