Arif Mansoori: Both SDK v13.0.0 and SDK v14.0.0 have Secure Bootloader examples ( found in the examples\dfu\bootloader_secure_ble folder) that should compile "out-of-the-box" with GCC. As far as I know Security_SVC_Handler()refers to an experimental implementation of an early bootloader with signing released with SDK v10.0.0

Hello Bjorn,

I am using V13 and V14 on nRF52382...

Arif Mansoori: Are you using SDK v13.0.0 on a nRF51 chip`?

Hello Bjorn,

Thanks for the clear explanation. Curious to know if the Security_SVC_Handler()has been ported for GCC now on what version?

I am getting the same error in V13.

Thanks

yes Bjorn After porting that SVC_Handler to gcc I can able to program it well and thank you very much for you nice explanation

The way it works is when nrf_sec_svc_verify() is called you're in reality passing a SVC number(and the arguments of nrf_sec_svc_verify()) SVC_Handler in dfu_ble_svc.c which based on this number branches to the address in flash where this function is defined( like sd_ -functions). If the SVC number is equal to 8 the SVC_Handler will branch to Security_SVC_Handler(), which in turn will branch to the nrf_sec module.

However, Security_SVC_Handler()has only been defined for the ARM compiler(__CC_ARM) and not GCC.

You'll have to port Security_SVC_Handler() from ARM to GCC and modify the GCC SVC_Handler() so that it branches to Security_SVC_Handler() if the SVC number is equal to 8

Hii Bjorn and sorry for my late reply when I tried I found that nrf_sec_svc_verify() returns with NRF_ERROR_SVC_HANDLER_MISSING error

Can you check if nrf_sec_svc_verify() returns or not? If it returns, please provide the err_code and if it does not return use J-Link Commander to see if it branches correctly to the nrf_secmodule or ends up hardfaulting.

does ECC module means nrf_sec.hex right? in that case I flashed that. Yes I know that but my point is like if the same code working in keil but giving the init packet error in eclipse can you guys suggest me where may the problem exist so that I can look in that area

Hi, have you loaded the ECC module to flash? Otherwise the call to nrf_sec_svc_verify() will not work, and therefore fail the pre-validation step. Note that we have not tested this particular example with GCC yet.

Pavan kumar — Mon, 25 Jan 2016 13:25:29 GMT

I believe that the problem should be in the prevalidation, because init packet will b handled by prevalidation, I go through the whole code but I didn't find any reason. But I really surprised because the same code that compiled in the eclipse working obviously fine. My question is like what may make difference in eclipse and keil

What debugging have you done to find the cause? Have you looked in the code to see what condition(s) would cause that message?
