Merge remote-tracking branch 'origin/develop' into mekf-invalid-reset-counter

CHANGELOG.md

@@ -16,13 +16,40 @@ will consitute of a breaking change warranting a new major release:
 
 # [unreleased]
 
+## Fixed
+
+- PAPB busy polling now implemented properly with an upper bound of how often the PAPB is allowed
+  to be busy before returning the BUSY returnvalue. Also propagate and check for that case properly.
+  Ideally, this will never be an issue and the PAPB VC interface should never block for a longer
+  period.
+- The `mekfInvalidCounter` now resets on setting the STR to faulty.
+
 ## Added
 
 - The event `MEKF_RECOVERY` will be triggered in case the `MEKF` does manage to recover itself.
+- The persistent TM stores now have low priorities and behave like background threads now. This
+  should prevent them from blocking or slowing down the system even during dumps
+  (at least in theory).
+- STR: Fix weird issues on datalink layer data reception which sometimes occur.
+- Syrlinks FDIR: Fully allow FDIR to do more recoveries. Assembly should take care of preventing
+  the switch to go off.
 
-## Fixed
+## Changed
 
-- The `mekfInvalidCounter` now resets on setting the STR to faulty.
+- Rework FSFW OSALs to properly support regular scheduling (NICE priorities) and real-time
+  scheduling.
+- STR: Move datalink layer to `StrComHandler` completely. DLL is now completely hidden from
+  device handler.
+- STR: Is now scheduled twice in ACS PST.
+- `StrHelper` renamed to `StrComHandler`, is now a `DeviceHandlerIF` directly and does not wrap
+  a separate UART COM interface anymore.
+- TCS: Local pool variables are members now.
+- Syrlinks: Create dedicated COM helper which uses a ring buffer to parse the Syrlinks datalinklayer
+  and should make communication more reliable even on high CPU loads.
+- Syrlinks: Two communication cycles per PST.
+- Fine-tuning of various task priorities.
+- The CSP router now is scheduled with the `SCHED_RR` policy and the same priority as the PCDU
+  handlers as well.
