Tool/software:
Hi Team,
We are working with the J722S 10.00 Linux SDK.
As per the DDR datasheet (MT53E2G32D4DE-046) the maximum operating frequency is 2133 MHz. But from the ddr.dtsi file of Linux side, I observed the Operating frequency as 1866 MHz ((i.e) PLL Frequency *2 = 933*2).
However, in the RTOS the PLL frequency for the DDR is mentioned as 933.25 MHz which makes the operating frequency as 1866.5 MHz.
Could you please let us know why there is a difference in the operating frequency of the DDR in Linux and RTOS.
Regards,
Ann Rose Antony
