Hello TI,
as per our requirement we would like to run ddr4 RAM at highest clock frequency.i.e 800MHz as per the datasheet.
I was check with current frequency with k3conf dump clock 138 it is showing below.
root@am64xx-evm:~# k3conf dump clock 138 |------------------------------------------------------------------------------| | VERSION INFO | |------------------------------------------------------------------------------| | K3CONF | (version 0.3-nogit built Sun Mar 03 08:52:05 UTC 2024) | | SoC | AM64x SR2.0 | | SYSFW | ABI: 3.1 (firmware version 0x0009 '9.2.7--v09.02.07 (Kool Koala))') | |------------------------------------------------------------------------------| |-------------------------------------------------------------------------------------------| | Device ID | Clock ID | Clock Name | Status | Clock Frequency | |-------------------------------------------------------------------------------------------| | 138 | 0 | DEV_DDR16SS0_DDRSS_DDR_PLL_CLK | CLK_STATE_READY | 400000000 | | 138 | 1 | DEV_DDR16SS0_PLL_CTRL_CLK | CLK_STATE_READY | 500000000 |
