Hi All,

I wanted to know much core current will be drawn by a ADSP -TS201S, under idle condition.
(Nothing is running in side DSP and DSP is in idle/halted condition.)

Because we have a TigesrSharc board which has a cluster of 4 DSPs ADSP TS-202S and which is drawing very high core current, 5 A for all 4-DSPs. So can you suggest me where would be the problem?

Even if i put all DSPs under RESET, then also its drawing much more current.
And in VDSP environment its shows clearly, all DSPs are HALTED and No interrupt is processing, No DMA operations are running.

So, please can you suggest me how to debug this??

Regards,
Sandip
