DFU on S130

[Yaroslav]

I'm developing application using your devices (PCA10001/PCA10000) and S130 SoftDevice. I tried to implement DFU/OTA feature in my app. For this purpose I used DFU sources distributed for Beacon "nRF51822 Beacon v1.1.0.zip" that based on S110. But I see that DFU takes a lot of RAM - about 5.5k that is acceptable for S110. As I use S130 that takes 10k RAM itself, leaving for application about 6k. So, I can't use DFU with S130 as it takes almost all available RAM.

Please correct me if I'm not right. Otherwise, please, suggest a way to use DFU on S130. Thanks.

@Yaroslav: It's true that the bootloader can take up quite a lot of RAM but it still fit into the 6K RAM available. You can also change the heap size to 0 to get the 1K ram allocated for Heap if you don't use dynamic memory relocation.

We have ported the bootloader on SDK v6.1 to work with S130, you can have a look here. Note that it's provided as-is.

Hi Yaro, The target "all" is defined in \Source\templates\gcc\Makefile.common. I would suggest you to try the example on github for S110 with gcc without any modification and make sure it worked properly first. After that you can try to port it for S130.

Which central device you used to update the firmware (and got stuck at 1%) ? If you use the MCP on PC, version 3.7 and above is not compatible with bootloader from SDK v6.0 Please have a look here.
