Hello All,

I am using SPC5studio version 5.2.3 and SPC560B54L5 board.

I have problem in using sprintf() library function.

In a normal application sprintf() works fine but while using it in bootloader application it is creating a problem with the below error. Tried inserting relevant header files (string.h,stdio.h) also reinstalled the Free PowerPC-VLE GCC 4.9.2 toolchain but still the issue.

Error log in console:

Kindly provide your suggestion to solve this issue.

Thanks in Advance,

With Regards,

R.Santhamurthy
