CCS/DRA756: Unable to single step through 2016.05 U-Boot

Part Number: DRA756

Tool/software: Code Composer Studio

Hi,

This may not be a CCS issue but I am hoping to get some pointers from CCS experts.

CCSV7  is able to single step through the 2014.07 u-boot very well. Breakpoints, source single stepping, assembly single step all work.

However when I used 2016.05 u-boot, I am unable to single step through the code. Breakpoints in the source work. However source single stepping or assembly stepping do not work. When I try to single step, the code runs till the next breakpoint.

I have checked the compilation options, disabled optimizations, increased level of debug information. None of this work in the 2016.05 u-boot. This most likely has something to do with the debug information in the u-boot binary. Can someone please help me figure out what information is missing? I can use that to set the corresponding compilation options.

Please let me know any information that you need (binaries, objdump output, linker maps, ..).

I am using CCS  7.1.0.00014.

U-boot 2014.07 uses GCC 4.7.

U-Boot 2016.05 uses GCC 5.3

regards,

Venkat
