Thank you for the confirmation.

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...
