Hi. I find this code github.com/.../nrf51-dfu-single-bank-ble I want to compile bootloader and download it on PCA10004. I have KEIL 5.12 and the project file of the link is for KEIL uvision 4. So if i try to compile it i incoming in few errors. Can you help me?? thank you.

Hi

The bootloader should work fine with Keil 5.12. This bootloader is for nRF51 SDK 6.0.0 and softdevice 7.0.0. So you download the zip file from Nordic's Github and then you include it in your SDK 6.0.0 folder. Sometimes when you unzip the zip file, there is created extra folder which makes your dependency files in the projects to be not found, since the project uses relative paths to dependent files. Could that be the case? What errors are you seeing when compiling?

Sorry my sdk is 6.1.0 and my SD is 7.1.0. Is this the problem? Now i see that MDK Version 5 - Legacy Support www2.keil.com/.../ i need to install it to work with the project file ? anyway I followed these steps:

1. download zip file from GitHub
2. extract zip file in my sdk folder in this path
3. open the project file uvision 4 that i find in arm folder
4. include the in include folder in compiler setup
5. compile all and the result is this

EDIT 23/12/14

ok now i try to open de uvision 4 project that i find in my 6.1.0 SDK folder in C:\Keil_v5\ARM\Device\Nordic\nrf51822\Board\nrf6310\device_firmware_updates\bootloader\arm So i only open it and click on Compile but this is the output ERROR.

Hi I do not think you need the lowest includes as they are a duplicates. The bootloader is made for SDK 6.0.0 , so insert into SDK 6.0.0 instead. There were some bootloader changes between SDK 6.0.0 and SDK 6.1.0.

[Stefan Birnir Sverrisson]

Ok, that compiles without errors on my side. Seems like you have problems with finding the sd_softdevice_vector_table_base_set function. Try to insert the bootloader into a fresh copy of the nRF51 SDK. You can get nRF51 SDK here as zip file.
