EVMK2EX: stress test for DSP

Willie,

You are looking for a Linux test to run on the C66x DSP?
I don't think Linux runs on the DSP, only on the A15.

Either way, a colleague who can assist has been notified of your query. Please expect some delay in our responses due to the holidays.
Thanks for your patience.

Hi Lali,

Thanks for the response.

Actually, we are looking for a way to do max power consumption for  our thermal/power team to do their verification.

So we want to make both CPU and DSP full load at the same time.

CPU side we have "stress" to do this, but have no idea on DSP side.

Hi Eric,

We build and tried to load linpack, we see problems happens as picture below.

We have checked /lib/firmware/ipc/ti_platforms_evmC66AK2E_core0/messageq_single.xe66  and it's no problem.

when load linpack, mpmcl load failed and dsp is in error state. From /var/log/syslog, we see error message. Could you please give some advise for this ?

Our linpack,out size is 314956 bytes. would that cause problem?

Many thanks.

Hi,

If mpmcl didn't work, can you directly use JTAG/CCS to load the DSP image and run?
