dev/ttyAML1 isn't accepted

[Alda2308]

I have this two serial ports onboard (/dev/ttyAML0 and ttyAML1)
but under ebus binding I'm not able select this serial ports. Sw is still asking for USB serial device (which is also connected) :

HANDLER_CONFIGURATION_PENDING
{serialPort=The value of /dev/ttyAML1 does not match the enabled options parameter. Allowed options are: [ParameterOption [value="/dev/ttyUSB1", label="/dev/ttyUSB1"], ParameterOption [value="/dev/ttyUSB0", label="/dev/ttyUSB0"], ParameterOption [value ="/dev/serial/by-id/usb-Silicon_Labs_CP2102_USB_to_UART_Bridge_Controller_0001-if00-port0", label="/dev/serial/by-id/usb-Silicon_Labs_CP2102_USB_to_UART_Bridge_Controller_0001-if00-port0"], ParameterOption [value="/dev/ serial/by-id/usb-1a86_USB2.0-Ser_-if00-port0", label="/dev/serial/by-id/usb-1a86_USB2.0-Ser_-if00-port0"]]}

I also tried change a link :

ln /dev/ttyAML1 /dev/ttyS1
and set ttyS1 under ebus binding, but also not accepted
