Hi,
As Rahul has mentioned in http://e2e.ti.com/support/dsp/tms320c6000_high_performance_dsps/f/115/p/180311/1214276.aspx#690561, almost two years ago there has been an updated package of the generic secure software (for c674x core, same as for L138). Unfortunately, the current downloaded version is still the one released in June 2011.
May I request that the updated version be released for downloading? Or may I get a preview copy of that via forum message or email?
Jeff
