I am using keil uvision 5, and trying to use example projects from lpc open.

Without changing any settings however, if I just try to load for example the rtos blinky project found at

lpcopen_2_10_keil_iar_ea_devkit_1788\applications\lpc17xx_40xx\keil_uvision_projects\ea_devkit_1788

When I compile I get this message:

.\keil_output\iflash_ea_devkit_1788\freertos_blinky_iflash_ea_devkit_1788.axf: error: L6002U: Could not open file ..\..\..\..\..\..\software\lpc_core\lpc_board\boards_17xx\ea_devkit_1788\keil_output\board_ea_devkit_1788.lib: No such file or directory

For which I can find no reason, because having inspected the directory, the file is indeed there.

Any help much appreciated

Hi Jonotree,
Looks like the problem is due to long path. Can you please place the lpcopen project directly in root location (i.e. c:\) and try again.

Example
c:\lpcopen_2_10_keil_iar_ea_devkit_1788\....

I have the same problem with the lpc4300 software.

..\..\..\..\..\..\software\lpc_core\lpc_board\boards_43xx\ngx_xplorer_4330\keil_output\core_m4\lib_lpc_board_ngx_xplorer_4330.lib

130 chars

when installed in the default root directory

E:\lpcopen_2_12_keil_iar_ngx_xplorer_4330

42 chars

giving a total of 172 chars (not counting the seperator and null that the windows api call will require for whatever reason).

The max file path on windows api calls is 160 characters.

Renaming the top level directory to

E:\lpcopen_2_12_kei

makes it work.

NXP should consider adopting the same directory structure for the Keil/IAR as they have for the lpcxpresso downloads to avoid this.

1.Go to "C:\lpcopen_2_10_keil_iar_ea_devkit_1788\software\lpc_core\lpc_board\boards_17xx\ea_devkit_1788"
2.Open "lib_lpc_board_ea_devkit_1788.uvproj"
3.Build this project (now keil made board_ea_devkit_1788.lib")
