Hello,
I want to add multi-image dfu over BLE to my NRF53. A simultaneous update seems to be the only option for this. Unfortunately, it seems we lose the ability to revert any images by default.
I see CONFIG_USE_NRF53_MULTI_IMAGE_WITHOUT_UPGRADE_ONLY allows it to revert, but will brick the cpunet when it does. Serial recovery isn't an option for us to recover from this.
- Is there any way to gracefully revert both cpuapp and cpunet images if one of them fails to run? If not, are there plans to add this?
- What is the use case for CONFIG_USE_NRF53_MULTI_IMAGE_WITHOUT_UPGRADE_ONLY if it bricks the cpunet core? Is it just for cpuapp image dfus?
- Does a simultaneous update require both images to be updated, or can either image be updated alone?
Kind regards,
Ian
