Pronlems building AN10995 - Bootloader

thomashavregaar — Thu, 20 Apr 2017 13:54:32 GMT

We are two students who are trying to implement a secondary bootloader on a LPC1114.

We are using LPCXpresso version: 8.2.2_60, and the LPCXpresso 1114 rev A. test board.

We are both new to the IDE and are trying to learn about bootloaders. via. NXP's forums have we found the http://www.lpcware.com/content/nxpfile/an10995-lpc1100-secondary-bootloader-software-v13, which we are trying to use as a base to learn from, but building the project results in several errors. these are

"cannot find -lCMSISv1p30_LPC11xx", for bothe application and bootloader, "make: *** [Application.axf] Error 1 " and "make: *** [Bootloader.axf] Error 1 Bootloader"

while the consol shows the following text refering to a problem.

Building target: Application.axf
Invoking: MCU Linker
arm-none-eabi-gcc -nostdlib -Xlinker -Map=Application.map -Xlinker --gc-sections -mcpu=cortex-m0 -mthumb -T "Application_Release.ld" -o "Application.axf" ./src/IAP.o ./src/cr_startup_lpc11.o ./src/main.o -lCMSISv1p30_LPC11xx
c:/nxp/lpcxpresso_8.2.2_650/lpcxpresso/tools/bin/../lib/gcc/arm-none-eabi/5.4.1/../../../../arm-none-eabi/bin/ld.exe: cannot find -lCMSISv1p30_LPC11xx
collect2.exe: error: ld returned 1 exit status
make: *** [Application.axf] Error 1

Thanks in advance

You need to import the missing CMSIS library project. From the QuickStart Panel, select Import project(s). From the Import projects(s) dialog, select Browse Project archive (zip). You'll find the CMSIS library version you need in the LPC11xx_OldCMSIS_Libraries.zip archive located here: Legacy -> NXP -> LPC1000 -> LPC11xx.

Thanks and regards,

The problem is probably not import related.

In the current setting, once you unzip the AN10995 file,

CMSISv1p30_LPC11xx library was built and put in the "Debug" directory.

However, the application library search path is:

"${workspace_loc:/CMSISv1p30_LPC11xx/Release}"

Here is what you should do:

From application project, go to properties/MCU Linker/Libraries/Library Search Path (-L)

Add:

"${workspace_loc:/CMSISv1p30_LPC11xx/Debug}"

Now, your application will seach both "Release" and "Debug" directory and link

"CMSISv1p30_LPC11xx" library correctly.
