Error configuring LPCXpresso v8.2.2

johnygeorgemala — Fri, 17 Feb 2017 00:09:25 GMT

I am trying to configure LPCXpresso v8.2.2, I tried in both Ubuntu and Windows. I am getting the same set of errors.

I am trying to build a project for LPC Chip 824.

I am getting this set of errors, from the LPC 824 Board Library. How can I fix it ?

Description Resource Path Location Type
undefined reference to `Chip_GPIO_Init' board.c /lpc_board_nxp_lpcxpresso_824/src line 204 C/C++ Problem

How can I fix it ?

'undefined reference' is a linker error. You need to make sure you link with the appropriate library.

Although you are not linking with a 3rd party library, this FAQ explains how libraries work.

Which other library should I include ? I have already included both board and chip libraries for Lpc 824. Moreover this error is coming from the lpv 824 board library.

You obviously have done something wrong, but I can't tell without seeing your project.

have you tried using the lpcopen examples, as is, and comparing the working projects with yours?

Hi George,

Please make sure you have imported the lpc_board and lpc_chip libraries to your workspace:

If they are already imported then delete them and import them again using the "Import projects" option from the Quick start panel:

You could also try using the LPC82x code bundle from the below page, you will need to import the common, peripherals and utilities projects:

Hope it helps!
