TWR-LCD Using FlexBus from K70

Hello, I'm trying to get the TWR-LCD module working via FlexBus from a TWR-K70F120M. I can get the screen to display content over SPI just fine, but I can't get any output when using the FlexBus interface. I read that there are problems with the IR circuitry interfering with FlexBus (www.utasker.com/docs/.../uTaskerV1.4_Kinetis_demo.pdf - page 10) and that the solution is to either remove some components from the board or cut a trace. Is this the case? Thanks!

[EDIT] OK, I neglected to mention that I was using an MQX project. It seems that when using the same Flexbus/LCD code on a bareboard project the LCD works correctly. Presumably then there is some problem with using Flexbus with MQX. I'll open a new question/discussion for that.
