It mentions that the problem comes from using a tool chain that is
configured for the ARMv5TE architecture for a processor that belongs
to another, less capable architecture (ARMv4T).

You always have to expect problems when using a tool chain that is set
up to support another architecture than the one you have.

Best regards,

It seems intuitively obvious to me, which  means  that  it  might  be
wrong.                                                 -- Chris Torek
