PIC32MX150 Harmonu TCP/IP ETHMAC driver error

Hi All,
I've tried posting in the microchip forums, but I've waited two days for the posts to be approved and it's still not happened!
Anyway - I was hoping someone could help with an error I've got using the harmony 3 configurator with MPLAB X IDE v5.30 on Ubuntu - it seems fairly buggy.

I'm trying to pull in the ETHMAC internal driver, which does nothing. Running MPLAB X IDE (v5.3) from the terminal I get the following error:

Code: Select all
<Configuration Database>[Info]: Setting default value drvPic32mEthmac:TCPIP_EMAC_MODULE_ID:_ETH_BASE_ADDRESS

<Harmony Database>[Info]: PIC32M Internal Ethernet MAC Driver Component

Which looks like an issue in the source code?

Any ideas please? I'm just trying to get a PIC32 to do some basic tcp send/receive and maybe some NTP if I'm feeling saucy :mrgreen:
