floating point unit

[paulhembrook]

Have used the 4337 board with the tools for a few projects. Have selected some projects and have built a workspace for actual product development using the 4337 on our own board.

Recently we have investigating using the 54102. So I took the ADC example and did some initial code development incorporating some filters. I wan't to investigate the time savings if I engage the floating point hardware. I went to the IDE (MCUXpresso) and select FPv4-SP(Hard ABI) on MCU C Compiler-Architecture, MCU Assembler-Archtecture and MCU Linker-Architecture. I did a clean and build and get the following error(s)

Don't know how to proceed from here !!

The error is being reported because you are linking libraries that have not been built with the same floating-point options. You need to build EVERYTHING that will be party of your application with the same floating point options - your code and any libraries that are being linked into your application.

I went back to the workspace and modified the settings for lpc_board_lpcxpresso_54102 and lpc_chip_5410x to have floating point unit. I did a CLEAN of both projects and a Build. I modified Compiler/Architecture and Assembler/Architecture in both projects to select FPv4-SP (Hard ABI). In my periph_adc project I did the same changes and also include Linker/Arhitecture.

I then went to my periph_adc project did a CLEAN and then a BUILD.

I got:

Not sure why power_library did not compile/link correctly ??

[converse]

Make sure you made all the correct changes for the libpower library - don't forget to do Debug and Release builds. Check the build log to confirm that it built with the options you expected.

[paulhembrook]

I do not have libpower as a project. I chaged the chip and board library. I went through and changed the boards and chip library setting for both Debug and Release. I am doing a debug build for the periph_adc. I see in libs folder in the lpc_chip_5410x project the libpower_m4f_hard.a file. But I did clean and build of the library after the changes and did my periph_adc project and I have the same error.
