Error building NXP SDK example project in Keil

[lkf]

Load project LPC802-EX-CODE-KEIL\Keil_Projects\led_face in Keil.

Try to buiild it, but many errors. What is the problem ?

[lkf]

I am able to compile the code successfully after I downloaded compiler 5.03.

Thanks for help.

[lkf]

There are 2 .lib files included in every project. These 2 .lib files are not included in the SDK download, so I need to rebuild them.

I am unable to rebuild the utilities_lib.lib. Below is the Keil output messages after build.

The warning msg ".... \core_cm0plus.h(104): warning: "Compiler generates FPU instructions for a device without an FPU (check __FPU_PRESENT)" points to line 104 of core_cm0plus.h, which is 

#elif defined ( __GNUC__ )
#if defined (__VFP_FP__) && !defined(__SOFTFP__)
#warning "Compiler generates FPU instructions for a device without an FPU (check __FPU_PRESENT)"
#endif

But I don't find where is __GNUC__  being defined after searching. 

Not sure what has gone wrong. I would like to know your Option for Target Setting for Compiler, ASM, and Linker, to do a cross-check.

1.I have read your error message, and the Compiler version you use is still Compiler 'V6.19'. After testing, there will be some problems when using Compiler 'V6.19', so it is recommended to install compiler 'V5' and recompile.

Below is your compilation output, marked in red for the compiler you used：

Rebuild started: Project: led_face
*** Using Compiler 'V6.19', folder: 'C:\Keil_v5\ARM\ARMCLANG\Bin'

2．About the issue encountered with 2.lib files not included in the SDK download. First, you need to recompile the "peripherals_lib" and translation "utilities_lib" projects, and then compile the "led_face" project.

Th Keil Pack Installer always showing these errors. Any clue ?

[Xu_Zhang]

The installation may fail due to network problems.
If the online installation fails, you are advised to install Pack in the offline installation mode as follows:

Default installation location after download

Then check in keil to see if pack was installed successfully

If the installed package is found, the installation is successful, and the other packs follow the same path.

Hi, thanks for quick reply.

this is the Keil toolchain I am using.

This is the software pack I used. It is showing as Deprecated Pack. How do know if installed correctly?

Follow as you suggested, double-click peripherals_examples to open the project.

Set led_face Project  "Active Project".

Rebuild and got these errors. It seems it's related to the toolchain or the software pack issue.

Hi,

lkf

Compiler Version 5 is no longer installed by default after Keil 5.37.

I used Keil version 5.31, did not encounter your problem, you can also try the same version of keil with me.

Download link: http://www2.keil.com/mdk5

 Where to download the required support pack:：https://www.keil.arm.com/packs/lpc802_dfp-nxp/devices/

Hi,

lkf

       I tried to test the LPC802-EX-CODE-KEIL\Keil_Projects\led_face program in Keil and it didn't seem to be a problem.

Here's how I did it:

1. Install the required support pack.

2. Double-click peripherals_examples to open the project.

3. Right click and Set led_face Project to "Set as Active Project".

In addition, you can check the keil version you are using and try to compile with keil version 5.16 or later.
