can't print unsigned int

Hi David,

If I do a printf with a literal string (printf("Hello world\r\n);) it works OK, but if I try to add printing a variable I get an undefined exception.

How're you declaring the variable, i mean to which data type are you assigning?

I have tried unsigned int (using %u) and int using %d or %i

Does any one have any thoughts?

I've gone through the wiki http://processors.wiki.ti.com/index.php/Printf_support_for_MSP430_CCSTUDIO_compiler#Debugging_printf.28.29_function

but it hasn't helped.  This is making development very difficult and I need to get this resolved soon.

Thanks,

David

Sorry David, this post somehow got missed. I'm forwarding this query to CCS expert for quick solution.

Thanks.

Some more info..we copied printf.c and _printfi.c from the RTS lib.  When the files are in our source everything works ok.

Any thoughts on this?

David, sorry about the delayed reply.

Is your code based on Halcogen?  What target/device are you running on?
Have you tried increasing the stack and heap sizes? This usually becomes necessary depending on the extent of C I/O.  http://processors.wiki.ti.com/index.php/Tips_for_using_printf

Yes, my code is based on Halcogen.  We are using TMS570 1227 and 0332.

I've tried increasing the stack and heap sizes but it has not seemed to have an affect.  I think I have gone through the wiki you posted, but I will double check.

David,

If you're still not able to get it working after going through the wiki link, would you be able to share your project (or a simplified version of it) so we can take a look and see if we can get it working?
