Note: This test relies on boardenv_* containing configuration values to define
|
|
the PHY device info including the device name, address, register address/value
|
|
and write data value. This test will be automatically skipped without this.
|
|
|
|
For example:
|
|
|
|
# Setup env__mdio_util_test to set the PHY address, device names, register
|
|
# address, register address value, and write data value to test mdio commands.
|
|
# Test will be skipped if env_mdio_util_test is not set
