  • make/custom/pc386.cfg: EXEEXT is not defined in application Makefile support. All other BSPs just use .exe directly on objcopy commands. This makes it consistent and allows external examples (network demos, examples-v2, etc to link.
  • Property mode set to 100644

30#| Set the value of RELOCADDR to the address where you want your image to
31#| load. If you'll be using GRUB to load the images it will have to be >=
32#| 0x100000 (1024K). If you are using NetBoot to load the images it can be
33#| >= 0x10000 (64K) AND <= 0x97C00 (607K) OR >= 0x100000 (1024K). The memory
34#| top is of course another limit. Make sure there is enough space before the
35#| upper memory limits for the image and the memory allocated by it to fit.
