download application error

[dnguyen2019]

Hi 

configure as:

ROM start: 0x26000

RAM start: 0x20002218

when I download application software , it pops up following error. 

I'm using keil uVison version 5.

I think this error comes up when you already have a SoftDevice present on your the board you are flashing to. You can use nrfjprog to erase the board completely and then download the code again.

so I have to download application first then a softdevice?

It means you already have a SoftDevice present on the board. You don't need to download it again. You can just download your application only. If you want to download the SoftDevice again, you will have to erase the the current SoftDevice on the board. You can do this using nRFgo Studio or nrfjprog.

I downloaded soft device from 0x00 to 0x26000

now I try download application from 0x26000 but it gave me an error?
