SK-AM62A-LP: How user can emulate AM62A3 by using AM62A7 EVM

Part Number: SK-AM62A-LP

Hello,

I'm looking for the way about how user reduce function by using superset EVM.

I understand how user reduce function for CPU and GPU by referring below.
* Resource Explorer document "3.9.2. Changing # of CPU Cores"
* Resource Explorer document "4.2.3. Porting GPU"

However, I could not find the way how user emulate lower spec version of MMA.
(According to datasheet, both A3 and A7 have same number of MMA and difference is TOPS of MMA.)
Is there any solution to resolve about above ?

Best Regards,

    Hello Ryuuichi Machida,

    The primary difference for A3 and A7 versions is the clock speed for the C7xMMA. The A7 devices are tested and guaranteed to run at the full 1 GHz clock rate, whereas the A3 devices are rated for a lower rate (500 MHz)

    You can emulate by using the 'k3conf' tool in linux to temporarily change the clock speed.

    List clocks: ```k3conf dump clock | grep C7X```

    Change clock of C7x to 500 MHz (1 TOPS for 62A3): ```k3conf set clock 208 0 500000000```

    Note that this can also be used to overclock the device if you so choose, but we can't guarantee it will be stable.

    Best,
    Reese
