AM6442: DMSS Clock Frequency

Part Number: AM6442

Hello,

I was trying to understand the frequency at which the DMSS runs, looking at the AM64x TRM (SPRUIM2J rev J, section 11.2.1.2.2, DMSS Clocks) I have found the following table:

I am using the AM64x-EVM which should have a MAIN_SYSCLK0 of 500MHz, so I expected 250 MHz for the DMSS, but the system firmware reports 500 MHz for the DMSS instead with the following code:

uint64_t dmssClkHz = 0;
SOC_moduleGetClockFrequency(TISCI_DEV_DMASS0_BCDMA_0, TISCI_DEV_DMASS0_BCDMA_0_CLK, &dmssClkHz);
DebugP_log("DMSS clock: %u Hz\r\n", (uint32_t)dmssClkHz);   /* prints 500000000 */

Which is correct: does the BCDMA run at 250 MHz or at 500 MHz?

I have also tested the same for the RING ACCELERATOR.

Thank you,
Thomas
