Freescale MQX™ RTOS 3.6.2 Release Notes

o New MAC-NET Ethernet module driver with hardware time-stamping support was
added to support Kinetis platform.
o RTC driver API enhanced to be able to work with MQX DATE_STRUCT data type
directly.
o Minor changes done in ADC and GPIO drivers towards generalizing the code across
multiple platforms. No functional change.
- Changes in the USB code
o KHCI Host code significantly rewritten to support new Register I/O maps unified
across ColdFire and Kinetis families. No functional change.
- The MQX documentation was updated:
Bug Fixes:
o Reference manual was extended by description of _lwevent_get_signalled() and
_task_create_at() API functions.
o Description of interrupt-level task priorities and NMI handling were extended in the
User Manual.
- In the PSP code
o The _task_get_template_ptr() and _task_get_td() now safely returns NULL for invalid
input parameter values.
- In the RTCS code
o Compressed domain names haven‟t been handled correctly in the DNS client parser.
Some DNS server responses were not handled properly.
o Memory leak in the DHCP functionality fixed. Memory was not de-allocated properly
during address renewal process.
o DHCP client requests were not sent complete. With some servers the client was not
obtaining the subnet information.
o UDP service fixed in order to receive frames to a proper socket in case the same
UDP port is open by multiple network interfaces.
- In the I/O drivers code
- Other
o ADC examples were modified to work properly also on MCF51MM, MCF51AC and
MCF51CN platforms.
o MCF52259 GPIO_PTCPAR_PTCPA macro values were fixed.
o KBI Interrupt functionality was fixed in the MCF51MM GPIO driver.
o IO_IOCTL_I2C_GET_BUS_AVAILABILITY command implemented in I2C driver for
ColdFire V3 family.
o IO_IOCTL_SERIAL_SET_DATA_BITS command behavior fixed in serial for ColdFire
V1 family.
o Slave functionality was fixed in DSPI driver for ColdFire families. The slave was
sending additional byte after normal data block.
o Shell “help” command was fixed to display detailed description properly.
