Hi,

It because of the uECC library. The debug information generated by GCC is not compatible with IAR. Try to compile the library without '-g' or compile with '-gdwarf-3' to override the default DWARF version.

hi,

Thanks for reply. 

Can you please share step to compile uECC? I have downloaded uECC library from github but haven't compile it.

Try to run the script below in \nRF5_SDK_12.3.0_d7731ad\external\micro-ecc. You need to have Make, Git, and the GCC toolchain installed (4.9 2015q3 release)

@ECHO OFF

:: This script will use git (must be in %PATH%) and arm-none-eabi tools in combination with GNU Make

IF NOT EXIST micro-ecc/uECC.c (

	git clone https://github.com/kmackay/micro-ecc.git

Hi,

I have run this script and output is shown below,

But still having the same error.

[Vidar Berg]

Hi,

You need to change the compile flag in the Makefile as well: "CFLAGS +=  -Wall -Werror -Os -g3" --> "CFLAGS +=  -Wall -Werror -Os -gdwarf-3"

Hi,

Thanks for reply.

I haven't got this error but still advertisement is not start and debug window show like below,

And I have also try to scan my device in nRF connect application but not show in my device.

Which memory variant of the 51 are you using? And does the bootloader work if you just program it nrfjprog, etc.? 

[Urvisha Andani]

Memory setting is as like below,

And use nRF51822 QFAA.

[Vidar Berg]

The memory settings are for the 32K RAM variant, while your chip has 16K. Try to change the RAM end address to 0x20004000 and start address to 0x20002500.

Edit: RAM base must be at least 0x200025e0 for the bootloader in SDK 12.3.0
