I have only just now looked into this, so I may not understand this fully, but judging from [this comment](https://github.com/KhronosGroup/Vulkan-Docs/issues/1150#issuecomment-572228230) to fix this issue, you need to use `swapChainImages.size()` renderFinishedSemaphores...

Right. It is just, the more easy/convenient it is to cross compile a version for an embedded board, the more people are willing to go through the hassle to do...

FYI, I have put up a [modified version](https://gitlab.com/z-s-e/vulkanquadsdl) of the code that fixes this as well.

Thanks! Unfortunately it has been quite a while since I last worked on a Vulkan-enabled embedded device, so it may take some time before I get to try it again....
