Re: [microblaze-uclinux] Howto access FSL with uClinux?

[Yan Lin Aung <yan_lin_aung@xxxxxxxxx>]

Hi

There is an example from ImpulseC using CoDeveloper.

The image filtering (in hardware) example makes use of
uClinux and MicroBlaze FSL interface.

It is also mentioned in the book: FPGA Programming in
C.

Hope this helps.

With regards
