CCE 3.1 - SLAA281b (mmc card example) - MSP430F2274

:) Immm, I found that by changing the size from 512 to 128 at line 80 in main.c

unsigned char buffer[128];

the error disappeared. So this does point to the resources not being enough suggestion. But why does IAR not complain about this?

I would say, yes, it does point to not enough RAM resources on that device.

I would suggest turning on the option to generate a map file for both IAR and CCE.  This would help highlight where the resources are being consumed.  There may be a number of reasons why it may fit with IAR versus CCE.  Drilling into the details will provide that clarity.

I did generate a map file but was not really sure what to look out for.

I presume this output is from the CCE toolchain as it was not successful.

The first thing to look at is the Memory Configuration.  This is what the linker command file included in your project communicated to the linker on the available memory resources of the specific device you are targeting.

Specifically, I would highlight the RAM line item.  This indicates that 0x400 of RAM is available (the length field), or 1024 bytes.  50 bytes have been allocated leaving 944 bytes available.
This summary indicates what has been successfully allocated to the memory map of the MSP430.

Now, please note the .bss section is currently 0x412 (or 1042) bytes in length.  This means the .bss section alone is larger than the available RAM memory.
There may be a few factors that is contributing to this.  Any alignment pragmas that may force the linker to place variables in a certain alignment in memory can eat up space.
Also, the C run-time library may be consuming resources.

Cool, that all makes sense. But as far as I can see there is no funny pre-processor or pragma directives so dont think its that. So it I guess its just that code was bigger then I thought. One question, there is the following two lines:

#define SPI_PxSEL         P3SEL

#define MMC_PxSEL         SPI_PxSEL

After compilation would those two line effectively become?

#define MMC_PxSEL        P3SEL

with SPI_PxSEL being left out? Or would SPI_PxSEL still be there taking up space? Or am i completely missing the point and #defines dont even go in RAM?

Thanks for the help,

Leon

Nevermind, sorted out the #define stuff :)
