AM3351 operating frequency

Other Parts Discussed in Thread: AM3351

We have a custom board based on AM3351 and it is a battery operated. What is the minimal operating frequency is possible on the AM3351. The current processor-sdk-02.00.02.11 supports the minimal frequency of 300MHz. Is there any changes to the current sdk possible that would reduce the frequency further.

Where in the SDK did you see this? The A8 MPU can go below 300MHz at OPP100.

In the BSP it is mentioned only 300MHz. But if see the errata sprz360g.pdf it can be operated at 275 MHz.

Whether this workaround can be added into future BSP..?

and also any further frequency reduction is possible in AM3351.

I cannot say whether this will be implemented in the future.

Thanks for your clarification. In the errata it says we can operate at 275 MHz, any further reduction is possible in operating frequency. The interface we are using McASP, I2C, uart, GPIOs, mmc for wifi and eMMC

You can reduce your DDR3 clock to 303MHz.
