Part Number: AM5728
Hi，
Here is the configuration I am using.
Sdk :ti-processor-sdk-linux-am57xx-evm-04.03.00.05
chip: AM5728
Board : custom board
Software : linux-4.9.69
I connect to the 9031 chip through the MDIO_MCLK pin.
Below is the relevant schematic:
The pin configuration is as follows:
{MDIO_MCLK, (M0 | PIN_OUTPUT | SLEWCONTROL)}, /* mdio_mclk.mdio_mclk */
{MDIO_D, (M0 | PIN_INPUT | SLEWCONTROL)}, /* mdio_d.mdio_d */
The manual states that the MDIO_MCLK pin frequency is supported up to 2.5Mhz.
But the frequency I measured with an oscilloscope was only 125K.
Is this because of what caused it? How can I make the frequency reach 2.5Mhz.
Thanks,
Better
