G2UL - Not able to get 200 MHz in HS200 mode

Hello,

We are working on Smarc G2UL Type 1 EVK from Renesas and we have seen that we are not able to get exactly 200MHz of clock in HS200 mode for the eMMC port but instead of that, we get 133 MHz clock in this mode.

Please see below the waveforms of the clock for G2UL Type 1 EVK.

We have designed our custom board as well based on G2UL Type 1 CPU with eMMC part# EMMC16G-TB29- 90F01 and in our board also we are not able to get exactly 200 MHz clock HS200 mode of eMMC but we get only 100 MHz in our board.

Please see below the waveforms of the clock for G2UL Type 1 our custom board.

Can you please suggest why we are not getting 200 MHz clock in both G2UL Smarc EVK as well in our custom board as well?

Thanks,
