How do i setup gazell secure libraries for 52810

[Mehmet Nuri]

In sdk 16 release notes i have read 52810 chips are supported for gazell secure libraries. But when i make the project port changes as described in "developing for 52810" page, i get the below error. I am using Keil uVision 5. I saw some lib files named 810 in gcc folder. but do i need to import all my code to gcc now ? or is there a workaround to get it working with keil ?

 

    Tag_FP_arch = VFPv4 instructions were permitted, but only citing registers D0-D15 (=6)
    Tag_ABI_HardFP_use = This code should execute on the single-precision variant derived from Tag_FP_arch (=1)
    Tag_FP_HP_extension = Use of the optional half-precision extension to VFPv3/Advanced SIMDv1 was permitted (=1)

I set the flag as "-DFLOAT_ABI_SOFT" and changed definitions from "FLOAT_ABI_HARD" to "FLOAT_ABI_SOFT". Didnt make a difference.

Hi,

The libraries for nRF51810 are only built for GCC, unfortunately. There is no way these can be used with Keil. So you will need to migrate your project to GCC with Makefiles or Segger Embedded Studio.

Is there a guide for how to do it using SES ? I have never used GCC in my life and need a starting point. And the program i will port is about 3000 lines....

Assuming you have not used something toolchain specific, then the code could be used as is, and it is just a matter of changing the project files. I suggest you start of with a suitable SES example project, and copy in your code and change the project configurations.

To get started with SES, you can look at this old tutorial series on YouTube which is still valid, and Getting started with nRF5 SDK and SES (nRF51 & nRF52 Series).

is there any flag to define in SES for using gcc files for 52810. Correct me if im wrong please.

I will convert a uVision to SES and add the 52810 gcc files to the project and delete nrf5 files related to gazell. When i compile, will it automatically use gcc file or do i need to define some flags for it. Or install a dependency ?

SES use GCC internally (though it has its own linker), so you use the same library. You simply add the library in the same way as you add a .c file (that would be gzll_nrf52810_gcc.a or gzll_nrf52810_sd_resources_gcc.a).

It will use the library file(s) you have included in the project, so you need to pick the right one.

sounds easy when you say it :) thanks for help i will do as you said.
