Cannot Fully Execute mkimg Script

[Spencer Deevy]

Hello everyone, it's Spencer again. I have successfully compiled and built
RTEMS for my desired board (Xilinx Zedboard), but I've run into an issue
with trying to convert the ticker.exe program to an image that U-Boot can
load it. I am using the following script:

#! /bin/sh

OBJCOPY_FOR_TARGET=~/development/rtems/compiler/4.12/bin/arm-rtems4.12-objcopy
OBJCOPY="$OBJCOPY_FOR_TARGET"

EXE_NAME=$1

START_ADDR=0x00104000
ENTRY_ADDR=0x00104000

${OBJCOPY} -R -S --strip-debug -O binary "$EXE_NAME" "$EXE_NAME.bin" ||
exit 1
cat "$EXE_NAME.bin" | gzip -9 >"$EXE_NAME.gz"
mkimage \
  -A arm -O rtems -T kernel -a $START_ADDR -e $ENTRY_ADDR -n "RTEMS" \
  -d "$EXE_NAME.gz" "$EXE_NAME.img"

OBJCOPY_FOR_TARGET is the path for the objcopy program used to create the
flat binary
EXE_NAME is where I pass in the path for the ticker.exe program to be
converted

I've tested it a few times and this is what I've determined thus far:

- The program fails when it tries to make the flat binary
- The error I'm getting is 'bus error (core dumped)'

I've checked that the paths are all correct, and I don't think it's a
permission issue.
>From googling around a bit it looks like it's an issue with trying to
access memory that is unavailable...

If anyone has any insight into this, I would greatly appreciate the help.
