KNOWN ISSUES

The current known issues are as follows:

  • Code is compliant to MISRA C 2012 Mandatory guidelines, with the exception of Rule 9.1 (Code 530). In gfx.c, the variable args is falsely detected in violation of Code 530: "Symbol not initialized" at line 358. In fact, va_start at line 358 is exactly where args is initialized.

  • When regenerating demo applications, keep all code between comments “//CUSTOM CODE…” and “//END OF CUSTOM CODE…”. Custom code is added to perform specific functionality.

  • Applications running on SAM E70 in combination with LCC will observe visual rendering artifacts on display during SD card R/W access. There is no loss in SD Card data.

  • FreeRTOS osal has an incorrect include path that causes build failures in non-Windows environments.

  • SAM E54/D51 must be debugged using MPLABX v5.25

  • For a list of current issues that affect this release, refer to MPLAB Harmony GFX Issues and Errata
