Use the web interface provided at: http://bugs.ecos.sourceware.org/show_bug.cgi?id=1001561 --- Comment #31 from Nicolas Aujoux 2012-07-10 14:24:46 BST --- Hi Ilija, Thank you for your help. I move the function into RAM as you mentionned and it works well. I added the patches that implement this functionnality and remove the flash limitation.
