We are using a LPC4078 controller in a product and would like to investigate using the the Hard ABI FPU to see if there is a performance benefit. Unfortunately it looks like there is not a version of the precompiled USB library that is part of LPCOpen that has support for the FPU configured with Hard ABI.

Is there a version of libusbd_40xx_lib.a that will work with projects that are configured to use Hard ABI?

Hi npeterson,

Sorry for the delay - I attached the hard ABI USBD library file for LPC4078.

Hi npeterson,

NXP can provide a Hard ABI version for LPCXpresso.  Which toolchain are you using?

Best regards,
