I am building using the GNU toolchain for a BF518. I have a warning message that I do not understand enough to solve.
bfin-elf-ldr.exe: count is not 4 byte aligned (0x11E6 % 4 = 2)
bfin-elf-ldr.exe: going to pad the end with zeros, but you should fix this
It seems that I have not padded a section or something like that. Can anyone help me understand the issue better so I can resolve it.
Here is the LDF file:
