writing 32 bit address to DSP Boot Address register in TI814x

Hello,

I am trying to bring the DSP out of reset and run the DSP Application Image from boot loader of A8.

When I write to the DSP Boot Address register (0x48140048) I am able to write only the upper 22 bits of the address. How to write the lower 10 bits?

If the DSP application Image has a lower 10 bits as 0 then the application Image runs properly.
Ex: If Boot address is like 0x8B00 0000 then application runs but if Boot address is like 0x8B00 06A0 then application doesnot run.

Please tell me where to specify lower 10 bits of the address?

Regards,
Prasad
