Dear all, Senthil.T had a linking problem similar to mine: 'C:\CCStudio_v3.1\boards\osk5912\lib\osk5912bsl.lib' has incompatible ABI I have visited the following link posted by Thomas Maughan to alexsc2005. But I still get the same linking error. ftp://ftp.ti.com/pub/private-cs/armcgt_releases/tms470_releases.html Has anyone a solution? Best regards, Amr Ayoub
