PetaLinux 2013.10 - Device Tree Generator Does Not Connect UART Node for MDM UART


I am using the UART mode of the MDM, but the Device Tree Generator does not propagate this device into the device tree.


In order for the Device Tree Generator to properly detect the MDM's UART mode, the MDM must be configured to have two specific configuration conditions:

1) The MHS file must specify that the MDM UART is to be used with the parameter C_USE_UART=1.

2) The interrupt line for the MDM must be enabled.

If either of these conditions is not met, the Device Tree Generator will not properly set up the MDM UART in the device tree.
