Hi Krishna,
Here is a link to the AM35x/OMAP35x PSP SDK download page for which Syslink 2.21 is supported: http://downloads.ti.com/dsps/dsps_public_sw/psp/LinuxPSP/OMAP_03_00/03_00_00_05/index_FDS.html
Here is a link to the release notes from that PSP: http://processors.wiki.ti.com/index.php/AM35x-OMAP35x-PSP_03.00.00.05_Release_Notes
The Linux kernel contained in that PSP is version 2.6.32, which is quite old but is the officially supported version for Syslink.
Hopefully those will get you started in the right direction.
Regards,
- Rob
