Oops! Defect in PDL 3.0.2 - fix coming very soon
We just discovered a problem in the SysPm driver that can cause the device to hang. It does not happen every time, only when the CM4 core is writing to flash and the CM0+ core wakes from deepsleep. The affected functions are as follows.
This is not an easy situation to replicate, so it slipped through our testing and we are concerned it might get through your's too. So we have pulled 3.0.2 from the web temporarily. We expect to have an updated release (3.0.3) live in two weeks.
If your application is using any of the above functions and putting the CM0+ core into deepsleep mode (sleep mode is safe) please back-rev to PDL 3.0.1. It is available for download from the PDL home page.
