DFU on S130

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.

  • I tried to use your ld file with additional sections but result is the same - bootloaders doesn't set UICR.BOOTLOADERADDR. Then I tried to build your whole GCC project by Eclipse and here I got make error: make: *** No rule to make target `all'. Stop. I also tried with project for Keil - I can build it and bootloader properly sets UICR.BOOTLOADERADDR. But when I tried to upload application using OTA downloader hangs at 1% of uploading.
