Rev0.1 - 8/28/2013 This is an update to the previous patch TWR-K21D50M lowpower Patch In MQX v4.0.2, most of the issues reported in the earlier patch have been fixed in the BSP.  But the lowpower example for this board still fails to enter LLS mode because of a conflict with the SPI peripheral.  There is only a minor edit in one file needed to fix the example. User_config.h MQX_ENABLE_LOW_POWER macro enabled.  Required for LPM driver and lowpower example. Disabled SPI0 peripheral before entering a stop mode lowpower example was aborting the stop mode entry, and never entered stop mode.  The issue was caused by the SPI0 peripheral preventing the entry to LLS mode.  Modified _lpm_set_cpu_operation_mode() in lpm_smc.c to disable SPI0 clock gate before entering a stop mode, and re-enabled after waking up.  If SPI0 peripheral is required in a stop mode, register the SPI driver with the LPM driver to properly configure when LPM changes operation mode to a stop mode.  Refer to LPM documentation for details.  Replace the file \Freescale_MQX_4_0_2\mqx\source\io\lpm\lpm_smc.c with the attached.

Que tal, Este documento es para toda persona que comienzan a trabajar con MQX . El documento describe como crear una tarea y como usar el driver LWGPIO. Esta escrito en español pensando en nuestros clientes de habla hispana. Saludos Sol

Hi, Many people has been asking about migrating from MQX RTOS to MQX RTOS for KSDK. Such guide is now available in the following link: http://www.freescale.com/files/soft_dev_tools/doc/support_info/MQXKSDKPUG.pdf?fsrch=1​ If you need to create a new MQX RTOS for KSDK project please note that there is not a New MQX for KSDK Project Wizard, therefore it is necessary to create it manually. You can find a guide in the link below. How To: Create a New MQX RTOS for KSDK Project in KDS Best regards, Carlos Musich Technical Support Engineer

The new Freescale MQX™ 4.1.0.1 patch release is now available on the www.freescale.com. ·         Files available          # Name Description 1 FSL_MQX_4_1_0_1_RELEASE_NOTE MQX™ RTOS 4.1.0.1 Patch Release Notes 2 Freescale   MQX RTOS 4.1.0.1 Patch This patch release is based on the MQX™ RTOS 4.1.0 release   and provides the solutions to software issues identified in the released   version. ·         Patch Description o   This patch provides the software workarounds for these issues identified in MQX 4.1.0 release: §  IPv6 ping issues ·         Crashes during a ping from an unknown host (IPv6 only). ·         An unhandled interrupt is generated when using the IPv6 ping. §  TCP/UDP issues ·         IPv4 sends an MSS and window size with a SYN. A SYN without an MSS or with a window size zero is dropped by some firewalls. ·         IPv6 UDP close issue. IPv6 only reuses the same IP and port. ·         Fixed the incorrect RTCS_selectset() unblocking. §  APP protocol issues ·         TELNET and Eth_to_serial peformance improvement. ·         HTTPSRV accesses data incorrectly in a session buffer while searching for SSI. ·         FTPSRV session close is missing a shutdown of a data socket. §  BSP issues ·         The TWR-K70F120M BSP is unstable when the DDR2 SDRAM is in high use due to incorrect DDR settings.

The new Freescale MQX™ 4.0.2.1 patch release is now available on the www.freescale.com ·         Files available # Name Description 1 FSL_MQX_4_0_2_1_RELEASE_NOTE Freescale   MQX™ RTOS 4.0.2.1 Patch Release Notes 2 Freescale   MQX RTOS 4.0.2.1 Patch This   patch release is based on the MQX™ RTOS 4.0.2 release and provides Software   workaround for Errata e7166. This   patch release applies to TWR-K70F120M and TWR-K60F120 board support packages. ·         Patch Description ·         This patch provides a software workaround for Errata e7166, which is relevant to the Mask 3N96B silicon. ·         Errata: SoC: SDHC, NFC, USBOTG, and cache modules are not clocked correctly in low-power modes. o   Errata Description: SDHC, NFC, USBOTG, and Cache controller modules are connected to a single master port on the crossbar switch through a multiplexer. While the modules are still clocked in Wait mode, the multiplexer clock, which is connecting the modules to the crossbar switch, shuts off at entry into low-power modes. This prevents the three modules either to complete bus transactions during a low-power mode entry, or to start new bus transactions when the system enters Wait mode (even though the modules themselves remain clocked in Wait mode). Because the cache tag clock and data RAM clock are gated off in Wait mode, cache contents may be corrupted at low-power entry. ·         Software workaround provided: To resolve the Cache Controller issue, all bus master operations for each module should be complete before requesting system entry into any low-power mode. o   To prevent cache corruption at low-power mode entry in idle task and low power manager, the WFI instruction is encapsulated in a special code sequence. The code sequence is executed from a memory location that is not cached (SRAM_L is recommended). Additionally, the code sequence must execute without interruption from the start of the code sequence to the WFI. If an interrupt occurs between the start of the sequence and the WFI instruction, MQX dispatcher code ensures that the code sequence is restarted from the beginning. ·         Known issues o   For known issues and limitations please consult the release notes document.

Rev0.1 - 8/28/2012 Adding to the patch at TWR-K21D50M lowpower MQX Patch for v4.0.2, this updates the MQX BSP and lowpower example to add VLPS mode. The example works the same as the default lowpower example, except after waking from LLS, the application immediately enters VLPS.  It uses the LPTMR to wake after 10 seconds, and returns to RUN mode and restarts the example.  Because the transition is immediate from the user perspective, the user will press the switch to enter LLS mode, after 10s the MCU will wake, turn on the blue LED, enter VLPS, wait another 10s, wake, turn off the blue LED, return to RUN mode and resume printing to the terminal.  There is no text printed to the terminal between LLS and VLPS to show a quick transition. This patch covers several files to enable VLPS mode in the twrk21d50m BSP, and modifies the lowpower example. The lowpower example is provided to demonstrate the MQX Low-Power Manager (LPM) driver, and change low-power modes on the K21 board.  The BSP in the release provided does not include support for VLPS. To use this patch, copy the patch directory into the MQX v4.0.2 root directory.  The patch will over-write some existing files in the MQX installation.  The changes addressed by this patch include the following: User_config.h MQX_ENABLE_LOW_POWER macro enabled.  Required for LPM driver and lowpower example. LowPower Example main.c Modified as described above to add transition into VLPS mode bsp_cm.c Added case for VLPS mode for clock mode transition init_lpm.c Added mode to LPM_CPU_OPERATION_MODES[] for LPM_OPERATION_MODE_VLPS init_lpm.h Added mode LPM_OPERATION_MODE_VLPS to enumeration LPM_OPERATION_MODE init_sci.c Added settings for mode LPM_OPERATION_MODE_VLPS to the _bsp_sciX_operation_modes arrays for all the UARTs in the BSP lpm_smc.c Added mode DOM_VLPS to LPM_PE_OPERATION_MODE_MAP[] Disabled SPI0 clock gate when entering stop mode, otherwise stop entry is aborted.  Re-enabled clock gate after waking up.  If SPI0 peripheral is required in a stop mode, register the SPI driver with the LPM driver to properly configure when LPM changes operation mode to a stop mode.  Refer to LPM documentation for details. Disabled the SysTick interrupt for the 5ms RTOS tick before entering stop mode, and re-enabled after waking up.  Without this, the example was entering VLPS mode fine without the debugger, but with the debugger the SysTick interrupt was causing VLPS entry to abort.
