Build uECC with IAR 8.22.1 returns Fatal Error[Li001]: could not open file "....\micro_ecc_lib_nrf52.a"

[Ran Ratson Kohavi]

Hello,

I'm using SDK15.0.0, device nRF52832 and softdevice S132.

After open "secure_bootloader_ble_s132_pca10040_debug-nrf52832_xxaa_s132" project and build it, I got:

Fatal Error[Li001]: could not open file "C:\Nordic Semiconductor\nRF5_SDK_15.0.0\nRF5_SDK_15.0.0_a53641a\external\micro-ecc\nrf52hf_iar\armgcc\micro_ecc_lib_nrf52.a"

I've followed this page to install micro-ecc library (performing steps 3-5 only because I'm working with IAR IDE).

I've been here and here but with no help.

How can I solve this problem?

Thank in advance for your help.

Hello,

The uECC library should be built with GCC, then linked in as a library in your IAR project. So you should not skip step 1 and 2 in the installation guide. Were you able to run Make without errors?

Hello Vidar,

Thanks for your reply.

Before installation of the micro-ecc library, I got dozens of errors of "can't open uECC.h file".

After installation these errors were fixed and the error described above is the only one I get.

I'll try to perform steps 1-2 hoping this will help.

Well, I don't really know what to do.

I've done the following steps:

1. Install GCC compiler here: C:\Program Files (x86)\GNU Tools ARM Embedded.

2. Download GNU Make to  ...\Downloads.

3. Add micro-ecc library to: C:\Nordic Semiconductor\nRF5_SDK_15.0.0\nRF5_SDK_15.0.0_a53641a\external\micro-ecc\micro-ecc.

4. Add the path of micro-ecc library to the IAR settings.

My project is here: C:\Nordic Semiconductor\nRF5_SDK_15.0.0\nRF5_SDK_15.0.0_a53641a\examples\dfu\secure_bootloader.

Now, how do I perform step 5 'Run make'?

[Vidar Berg]

'Make' must be run from the command line in the \external\micro-ecc\nrf52hf_iar\armgcc directory. You can also run the batch script located in the micro-ecc folder (build_all.bat). Let me know if you get any errors.

What should I do with the extracted 'make-4.2' folder ,or where should I locate it ?

Now I get "'make' is not recognized as an internal or external command, operable program or batch file".
