• Built-in functionality support
  • This supports registering a TASH command by modification of Makefile without calling any TASH public API in source codes.
• TASH commands enhancement
  • The heapinfo shows peak value of heap dynamic usages for all and per threads.
  • New command, uptime, to show the time of system running has been added.
• New make options support

  • “make applist” and “make appupdate” make easily control applications without menuconfig on Tizen RT IDE only.
• New debug script support
  • The g_var_profiler script shows variables which size is greater than input argument for RAM static footprint.

Fixes

• Deadlock error of mutex on idle task has been fixed.
  • -1 instead of 0 as a PID element for unclaimed mutex at initialization has been used, because 0 means idle task. It causes deadlock error.
• Memory corruption on data abort handling has been fixed.
  • Separated stack for data abort handler has been used, because data abort handler can save the information to outside of stack when stack is almost used. It causes memory corruption.
• Abnormal operation on localtime has been fixed.
  • Wrong conditional usages and wrong structure usages have been fixed.

Network and Connectivity

New and Changed Features

• LwIP protocol stack parameters can be configured through menuconfig.
• TLS support (HTTPS) for webserver and webclient has been added.
• TLS support for websocket has been added.
• CoAP protocol support has been added.
• Posix-compatible pthread cancellation point for LwIP has been added.

Fixes

• Semaphore usage on sys_arch.c has been fixed.
• LwIP stack has been fixed to be more robust to TCP spoofing attacks.

File System

New and Changed Features

• Automount functionality for userfs, romfs on ARTIK053 and SIDK_S5JT200 boards has been added.
• Scripts have been added to make a romfs image automatically by makefile.
• The Sudden Power Off Recovery functionality has been added.
  • Basic CRC checking process has been added to check bit-flipped sector due to sudden power off situation.
  • Logic has been added to find bit-flipped sector.
  • CRC has been added to check validation of Journal logging entry and data.

Known Issues

• There are some duplicated code of bit-flip checking logic.
