On IMX53 Quick Start board http://www.nxp.com/products/interface-and-connectivity/interface-and-system-management/switch-monitoring-ics/i.mx53-quick-start-board:IMX53QSB

With Debian Jessie I'm installing: https://www.haskell.org/ghc/download_ghc_7_10_2\#linux_armv7 ghc-7.10.2-arm-unknown-linux.tar.xz (108 MB)

When I compile simple program as: import System.IO main = putStrLn "Hello World in ARM!"

and then compile and run I got: "Illegal instruction" message

When we debug it it seems that there is missing end of function and going straight into main function without changing to ARM Thumb instructions.
