This is a very design specific question. Without knowing a lot of detail about the EPM240 design and how the JTAG rig works, no - there's nothing I can suggest.

When you try to access the secondary chains can you see the JTAG signals, on an oscilloscope, being driven? Are the 'ADSP' chips TDO responding?

Cheers,

Alex
