Error while flashing nrf51422

[Mabbas]

Hello,

I want to falsh nrf51422 device. I ma developing software using Eclipse and SDK_7.2.0. The soft device is 130. I have build the project successfully and Hex/elf file is generated.

But when i tried to flash the device it is not flashed proper and got an error as following: ...Target halted (PC = 0xFFFFFFFE).

I am using the jlink debugger for flashing the device.

Should i flash the soft device separately to controller? or there is no need of that? could you please help me to figure it out?

Regards

MAbbas

Yes, you need to flash Softdevice first. This is only require once unless softdevice is overwritten.

Could you give me link for hex file of softdevice 130 ?

look in the SDK under components/softdevice

Hi i am using SDK_7.2.0 and i looked into the components/softdevice but there is no hex file for the softdevice. Could you tell me the where i can get the hex file for softdevice? Another thing is the do i also need bootloader? if yes could you tell me where it should be located?

That SDK is too old. You may need to go to nordicsemi website to download.
