Status: Open

Title: I2C TOOL PATITIONING
Description: The tool at apps/system/i2c makes direct calls into MCU level
I2C logic within the OS and, hence, violates the OS/application
interface. An I2C character driver will need to be developed
to perform the I2C interactions within the OS; the I2C tools
will need to be modified to use that driver to perform the
I2C accesses.
Status: Open
Priority: Medium. Until this change is made, the I2C tool will not be
availabel in protected or kernel builds.
Title: C++ CONSTRUCTORS HAVE TOO MANY PRIVILEGES (PROTECTED MODE)
Description: When a C++ ELF module is loaded, its C++ constructors are called
via sched/task_starthook.c logic. This logic runs in protected mode.
