Unfortunately there is no good workaround for this issue at the moment. The only workaround I can think of is to handle chip select manually from the application, rather than have the driver set it for you. This would only work if you use the SPI driver directly though, it won't work if the SPI driver is interfaced through some other higher level library or driver.

One of the developers proposed a fix to this issue, and created a PR which you can have a look at here.

You could try to patch this in manually and see if it solves it. Patching SDK files directly is not ideal either, but it might be the lesser of two evils in this case (and would be a temporary fix until the PR is merged into an SDK release).

Best regards
