Symptoms of Known Issues

Symptom

The system sometimes goes to a black screen or HOME does not work if the SD Card is removed during sleep.

Frequency of Occurrence

Extremely rare.

Affects

All applications.

Support Period

TBD

Symptom

The system sometimes stops on a black screen if a FATAL error (including card removal error) occurs at the point the system is closed.

Frequency of Occurrence

Occurs at a high frequency if the timing is right.

Affects

All applications.

Support Period

TBD

Symptom

If an immediate background execution process enters retry status after its first execution, the retry is sometimes not executed if the clock is subsequently set back by one hour or more.
Ordinarily, when a task for immediate background execution enters retry status, it will be executed immediately, as soon as the next task can be executed. When certain conditions are met, however, the task will not be executed within the predetermined execution interval.
Specifically, this occurs under the following conditions.

1. When a task enters retry status due to turning wireless communications off or the system enters sleep mode after the immediate execution of a NADL task registered for periodic execution.
2. When the clock is set back an hour or more under system settings.
3. When a task is executed due to retry. Retry status occurs again at this time.
4. If conditions 1, 2 and 3 are met, task execution waits until the next execution interval regardless of retry status.

Frequency of Occurrence

This problem always occurs if the conditions are satisfied.

Affects

All applications that use immediate background execution of BOSS tasks.

Comments

If you launch the application after the symptoms above occur, the application can confirm the status of the task. If the task's execution count remains equal to the maximum value, and the status is still TASK_RETRY, then this symptom can be alleviated to a certain degree by cancelling the task and then setting it for immediate execution again.

Symptom

Sometimes one of the following two FATAL errors occurs when the SD Card is removed during ROM access.

RSL : 0xD9004588
      Level  : -5
      Summary:  8
      Module : 17
      Desc   :392

RSL : 0xC8A0F001
      Level  : -7
      Summary:  5
      Module : 60
      Desc   :  1

Frequency of Occurrence

Extremely rare.

Affects

All card-based applications.

Support Period

TBD

Symptom

A fatal error (0xF8A02A09) occurs when the system is opened and closed rapidly.

Frequency of Occurrence

Extremely rare.

Affects

All applications.

Comments

This issue appears to be caused by an increase in driver cost as a large number of graphics command requests are gradually issued in the application processes that are called when the system is opened and closed.

nn::gx::SetInternalDriverPrioMode(nn::gx::INTERNAL_DRIVER_PRIO_MODE_LOW);

Calling the driver priority function may improve the symptoms of this issue, but it may also slow down the graphics processes slightly.
