Hi Simon,

Could you please explain the used of #ifndef(USE_HOSTCC) in the rsa_verify_key function in rsa-verify.c? I've written a HW hashing driver and need to use the software mod-exp function as we don't have a hardware driver for this (yet.) I get all kinds of compilation errors if USE_HOSTCC is explicitely defined (say in a config header.) You're advice would be appreciated.

It's there to allow the host compiler to build it - I think it is used by the fit_check_sign tool to check that the signature matches.

You shouldn't define USE_HOSTCC unless you are building host tools. If you are building for a target then it should use the target compiler.

Regards,

Andre.
