sdbgp starts sysmemChecker if DIP switch 224 is on.
It is possible to interact with SDbgp from host computer via PSP2TMAPI. See [[Dbgp protocol]] for details.


sysmemChecker has 4 operations:
=== Background Sysmem Checker ===
   0: verify heap
 
If DIP switch 224 is on, SceDeci4pSDbgp creates a workqueue and schedules the <code>sysmemChecker</code> task on it.
 
The Sysmem checker performs one check at a time before scheduling the next one (modulo 3).
A 20 seconds delay is observed after check completion before scheduling the next check on the workqueue.
 
The checks are performed in this order:
   0: Verify Sysmem heap

   1: PhyMemPart check
   2: Partition check
   2: Partition check
   3: FixedHeap check
   3: FixedHeap check
=== System Debugger ===
sdbgp has an debugger via PSP2TMAPI.
You can send System or Kernel debug commands by sending any command with <code>ITarget.SendCustomProtocolData(uint uProtocl, object Packet);</code>.

It is possible to interact with SDbgp from host computer via PSP2TMAPI. See Dbgp protocol for details.

Background Sysmem Checker

If DIP switch 224 is on, SceDeci4pSDbgp creates a workqueue and schedules the sysmemChecker task on it.

The Sysmem checker performs one check at a time before scheduling the next one (modulo 3). A 20 seconds delay is observed after check completion before scheduling the next check on the workqueue.

The checks are performed in this order:

 0: Verify Sysmem heap
 1: PhyMemPart check
 2: Partition check
 3: FixedHeap check
