I am using the rtems blackfin tools to build and debug my board that
contains analog devices BF527 processor.
The issue i am facing is that I am not able to place breakpoints in some
part of my c code. So the debugging is becoming difficult. GDB complains
"No line 291 in file" even though the file has more that 300 lines of code.
I use the compiler, debugger provided by rtems4.11 for debugging my
After some debugging and analysis of the mapping the line number in the elf
to the C code in the file using objdump i find the following.
1. executing the bfin-elf-objdump ( analog devices toolchain) on the elf
the following error is thrown out
BFD: Dwarf Error: mangled line number section.
2. but the objdump from rtems does not complain.
How do i correct the issue in the rtems blackfin gdb?
I also observe that analog devices have their own gdb-proxy but rtems does
not provide gpd-proxy
should the gdb-proxy also be included in the rtems bfin toolchain?
