Hi Raghavan,

I think that porting ELKS to the Blackfin is a waste of time. ELKS is
written to take advantage of 8086 processor quirks. The Blackfin (or MSA)
architecture is quite a bit different.

(1) The Blackfin does not have an TLB based MMU. You cannot use Linux,
but you can use uClinux. ELKS is similar to uClinux but the memory models
are very different.

(2) You may want to start using uClinux. There already exists a port for
Blackfin. You will probably have to contact Analog Devices to get more
information regarding this.

Regards,
Faisal
