Thank you for the confirmation. I have checked in the RedBoot
configuration fixes.

Implementation of the RedBoot "exec" command is architecture-specific
and typically provided by the various eCos architectural HAL packages.
There is no support for RedBoot "exec" in the Cortex-M architectural HAL
package at present. Take a look at redboot_linux_exec.c and
CYGPKG_REDBOOT_ARM_OPTIONS in the ARM architectural HAL package, clone
for Cortex-M and modify as required.
I hope this helps...
