AM625: CPU running at wrong frequency (1GHz vs 1.25GHz)

Hello Emanuele,
Thanks for your inquiry.
Let me have a closer look, and get back to you next week.

I would say that by using >=09.01.00.004 ti-linux-firmware I get rid of these messages:

cpufreq: cpufreq_online: CPU0: Running at unlisted initial frequency: 1250000 KHz, changing to: 1000000 KHz

So seems to be fixed. Can you confirm?

Which of these fixes, reported in the commit message, is related to this problem (may be the second last?)?

    - Additional Klocwork MISRA-C issues addressed
    - am62ax: LPM DeepSleep support
    - am62x: LPM Partial IO mode support
    - am62x/am62ax/am62px: ARM PLL initialization skipped in pm init
    - am62px: MCU_OBSCLK_MUX bitfield issue fix

I assume that actually the clock is correct before linux starts.

But when is it set correctly?

Before or after dram_init in R5 SPL?

At which frequency was (before this firmware) running the dram_init function before this firmware?

Thanks a lot Vishal,

I'll be back soon confirming that this resolve our "issue". In first instance, our issue, was to run AM62x to "correct" frequency... and we hope that should help us also about this issue: e2e.ti.com/.../4827908

Hello Emanuele,
Please keep us posted with your test on your setup.

Hello Hong,

now we get rid of cpufreq messages from linux kernel.

About the other issue linked it doesn't solve. But, at least, this reduces what we are searching for.

Thanks,

Emanuele
