I would suggest v.9.0.0. There is not much of a difference between SDK v.8.1.0 and 9.0.0 unless you are using the ANT stacks, which means that the migration process should be about the same for both versions. Please see release notes for more details.

Vidar, I could switch to SDKv8.1.0 but it requires a lot of changes in my code. If I switch over, should I switch to 8.1.0 or to 9.0.0 then?

GCC support for DFU was added in SDK v.8.1.0. So if you can use the latest one you would not have to do any patching to the old SDK. However, if you need to use this version you can always backport the files mentioned above from SDK 8.1.0/9.0.0 to SDK 7.2.0, which should be pretty straight forward.

Vidar

have you been able to complete the application DFU functionality porting to GCC? Is that code available somewhere ?

Is there a definitive example based on the 7.2 SDK that demonstrates how to compile the bootloader for the S310 using gcc? I have an existing working bootloader modified from the SDK 6.0, but it does not have support for DFU of the SoftDevice or Bootloader and I need to add this. I have integrated your changes here into my codebase + 7.2 SDK, but I'm afraid I have too many disjointed pieces and I'm not sure what the required key changes from SDK 6.x to 7.2 for DFU are in order to ensure support for DFU of SoftDevice and Bootloader? A definitive example or guide to the changes would be helpful. Thank you!

Hi, I was able to port the s110 bootloader to work with gcc, but without Experimental - Application with DFU Service support I.e., it doesn't work with the application to bootloader jump, so you need to be in bootloader mode to do DFU. The same approach should also work with s310 by changing the linker settings accordingly.

The application DFU functionality requires porting of the dfu_ble_svc.c,bootloader_util_arm.c and bootloader_settings , which I was not able to complete.

Note that the bootloader start address was reduced to 0x38000 to enable debugging. Thus, BOOTLOADER_REGION_START needs to be changed to 0x38000 in dfu_types.h as well.

Attachments: gcc_nrf51_bootloader_xxac.ld, makefile and dfu_ble_svc.c

I have the same issue, does anyone have an example of bootloader with s110 with SDK 7.2.0 ?
