I want to run the LPC1347 USB Rom drivers with the Rowley compiler but it always crashes to Hard Fault.
I am running example code from LPCWare suggested by NXP. I am running LPCXpresso board.

I can run the exact same code on Code-Red compiler and it works correctly. I run it on Rowley, it always crashes when I call the pUsbApi->hw->WriteEP function.

Thanks for your help.

I fixed this problem. It was a simple matter of needing to increase the stack size going from C to C++.
The Rowley compiler fooled me becaue I thought I had alreading increased the stack, but it didn't actually get set in the project properties.

I am asking Rowley about it.

The moderators can delete this issue if they want, since it is trivial and not really about USB.
