Hi,
We are designing a 66AK2E05 custom board and we are using PLL settings different from the EVM board.
The EVM board has following clock frequencies:
NETCPCLK : 100MHz
DDRCLK:100MHz
CORECLK:100MHz
SGMIICLK:156.25MHz
Whereas in our custom board, we have NETCPCLK: 125MHz and DDRCLK:125MHz; the CORECLK and SGMIICLK are the same.
I am trying to change the EVM board's frequency to match our new clock frequencies through changing output of clock generator in the BMC.
But, I wanted to know what changes should be done in U-boot and Linux source code to match these changed NETCPCLK and DDRCLK frequencies? I am using "ti-processor-sdk-linux-rt-k2e-evm-03.03.00.04" to build Uboot and Linux kernel images.
I am using UART bootmode once initially and then through TFTP, get a new Uboot image and burn to SPI flash and use SPI bootmode later on.
Can you please let me know the U-boot and Linux kernel source code changes needed to make the board boot up with these changed clock frequencies?
Regards,
Ashwini
