Hi,

The following errors occur when i try to build a simple "hello world" application.

Any help would be greatly appreciated.

    The 'hello world' example pulls in a lot of libc - IIRC it is about 70k code - probably larger than your internal memory.

    You need to select the small libc.

    That worked. I had to create a new project with the small lib template, but this work fine. Thanks for your help!

    This is incredible, I made the shortest program I've ever made and received this error with a 20kbyte memory. I had to switch to Small C Library too (BSP properties). Is there any documentation about the implications of this option?

    Everybody does it :-) Feels like taking a trip on a time machine somewhere to 80s, right? :-D

    Hi All

    I've the same issue.... :-( But I'm not able to create a small C library, could you please explain to me where can i find this option?

    Is it also possible to load all into DDR ram?

    I'm at 87.9 mph but I can't go haed...

    I've found the small C library, but is it included printf function?

    Thanks

    printf() is excluded from the small C library because it pulls in quite a lot of dependand code (basically all the stdio code and malloc/free).

    It is possible to write a standalone snprintf() that is under 1800 bytes (without long long or FP support) - does need __udivsi3 though.

    IIRC the small C library does contains some functions to print strings.

    Hi All

    Now I can see on my LCD many strange characters only on the first row. I've performed the basic procedure for clear start from position 0 and print same characters. But the result is completely different from desired, Very strange characters are shown by first row,nothing on the second row.

    Coud someone help me?

    How is it possible?

    where can i study something?

    Thanks
