I see this on the new EZSDK page:
Attention C6A816x/AM389x Users: If you have an older EVM that supports only DDR2 Memory, then only the older 5.00.00.56 release is available for direct download. Please find the software downloads for DDR2 EVMs at the 5.00.00.56

Are owners of the DDR2 EVMs out of luck?
