Q: To minimize i.MX6DL power consumption at stop mode, but needs i.MX6DL to wake-up by USB resume signal from Host PC. Can LDO_2P5(VDDHIGH_CAP) be powered off at stop mode in order to resume i.MX6DL by a USB resume signal that Host PC sends to i.MX6DL USBOTG(us as device mode only)? In other words, can USB OTG detect resume signal from Host PC and generate wakeup interrupt during stop mode with following LDO condition? -          LDO_USB is enabled and powered by USB_OTG_VBUS. -          LDO_2P5 is disabled during stop mode. -          LDO_1P1 is enabled during stop mode. The system uses LPDDR2, hence LDO_2P5 can be powered off at stop mode(I know this is not allowed for DDR3 as DDR IO need 2P5 as pre-driver). Actually tested on SDP, the system can not be resumed without LDO_2P5 as DDR IO need 2P5 for DDR3. A: Please note that disabling the LDO_2P5 supply, you are also disabling the DRAM, as the DRAM pre-drivers are powered by this supply(!). SDCKE is pulled down on the board, and it ensures that the DRAM is in proper state during DSM without LDO_2P5 power. we recommend to keep LDO_2P5 on at any mode(include DSM mode). ldo_2p5 is also one of power for USB phy.   4.3.2.2 LDO_2P5 The LDO_2P5 module implements a programmable linear-regulator function from VDD_HIGH_IN. The LDO_2P5 supplies the SATA Phy, USB Phy, LVDS Phy,   Actually I have tested on SDP, but we cannot resume the system without LDO_2P5 as DDR IO need 2P5 for DDR3.

Seeing a block diagram in IMX6SLRM 1.5.1, it looks like i.MXSL has Touch Panel Control. Is there interfaces for touch panel  in IMX6SL? Otherwise if I build HW using ADC or GPIO, can I be provided some SW drivers? Regards. The i.MX6 SL does not have embedded touch / ADC interface, sorry.

Q: In mfgtool release 1.0.0 I, "Support only Cortex-A5 as primary boot core (Cortex-M4 boot is not supported on this release)." When will a version supporting M4 boot first be available? A: Mfg tool is based on it's counterpart, the ROM code. Rom code is for the A5 and not for the M4 as a matter of fact if you boot with the M4 and the device doesn't enumerate on the USB port at all then you know why and the MfgTool won't be able to do anything about it. Currently there no plans to provide a MfgTool version that supports boot from M4 core. Customers can modify the exisiting code to make it work with M4 as primary core. Booting from USB with the M4 core should work. The image that is booted must be for execution on M4 (thumb mode). MfgTool uses u-boot and a micro linux kernel to download images and program memories. This Linux can only run on the A5 core. To make it work with the M4 core as primary, it should be sufficient to add some code to the exisiting A5 images. Code will execute on M4 and start the A5 at the proper address as if it is booted from the A5.

Q: To do a triple display demo based on imx6 SDP. The 3 channel are 1 lvds & 1hdmi & 1 lcd  and the OS is Android JB4.3.

Hi, this is a smart server called Duckbill in a thumb-drive format based on the i.MX283. It's a really low cost solution usable with or without casing. It is intended to be set up as a small home-server for automation purposes. It comes with Debian Linux as operation system but without any specific user programs.  The stick can be operated either at a USB power adaptor or at a USB port of your router.  Since Duckbill runs Linux you are totally free in software development. The internal connectors can be used as UART, SPI, I2C, ADC or GPIO. So it's up to everyone to develop his own expansion board. 1. Duckbill without casing (top) 2. Duckbill without casing (bottom) 3. Duckbill with casing 4. Duckbill for development purposes 5. Duckbill with integrated EnOcean module If you want to know more about this product: http://www.i2se.com/homeautomation.html

If someone wants to use the OpenGL ES 2.0 extension "GL_OES_vertex_array_object", the macro "GL_GLEXT_PROTOTYPES" must be defined in his program first. Then he can get the extension program location by calling the API eglGetProcAddress.  Here is an example to use this extension. #define GL_GLEXT_PROTOTYPES PFNGLGENVERTEXARRAYSOESPROC glGenVertexArraysOESv; PFNGLBINDVERTEXARRAYOESPROC glBindVertexArrayOESv; PFNGLDELETEVERTEXARRAYSOESPROC glDeleteVertexArraysOESv; glGenVertexArraysOESv = (PFNGLGENVERTEXARRAYSOESPROC)eglGetProcAddress ( "glGenVertexArraysOES" ); glBindVertexArrayOESv = (PFNGLBINDVERTEXARRAYOESPROC)eglGetProcAddress ( "glBindVertexArrayOES" ); glDeleteVertexArraysOESv = (PFNGLDELETEVERTEXARRAYSOESPROC)eglGetProcAddress ( "glDeleteVertexArraysOES" ); After these steps, the new alias glGenVertexArraysOESv, glBindVertexArrayOESv, glDeleteVertexArraysOESv can be use to call the VAO operation function in OpenGL ES 2.0 extensions.

When I use QMediaPlayer (Qt5.1.1) to play a FHD video, the CPU (imx6dl) usage turns very high and the output is not fluid and also has some frame drop. I found a patch that claims to solve this problem (links below are taking about the same thing) : adding zero-copy-QSGVideoNode for imx6 - Qt by Digia https://www.mail-archive.com/[email protected]/msg08580.html After patch appliance and recompilation of Qt Library and program rebuild, the performance issue remains the same. Does anybody know how to enable this property correctly? Have I missed some points or mandatory steps? Any comment will be appreciated, thanks!

In the older code, headphone router is always on, it is not a good choose for low power demand. This patch uses imx_hp_jack_gpio.jack_status_check to instead of w->event. It enables Ext Spk and disables Headphone Jack when Headphone Jack is plug in, it disables Headphone Jack and enables Ext Spk when Headphone is out.

Hypoxemia is a common clinical condition associated to several diseases that affect the respiratory system, including not only the lungs diseases, but also cardiac, neurological, neuromuscular and chest wall diseases. Its occurrence bring serious risks being essential its detection for appropriate treatment, and even to prevent the death of the patient. Hypoxemia is defined as the low saturation of oxygen carried by the blood. The most efficient way to determine the oxygen saturation is the gasometry, an invasive method (through the collection of blood) which is able to determine the gases present in the blood as well as its relative amount, as well as other data related to the blood. The Oximetry is a less effective method, but not least important, because of its practicality for not being an invasive method. Depending on the quality of the equipment, it can ensure very small variations with respect to the gasometry. In some cases, the constant monitoring of oxygen saturation is required. The portable oximeters are useful in such cases due to their ease of use. For monitoring oxygen saturation in the blood and also the heart rate, the machine suitable for this purpose is the Pulse Oximeter. Such equipment can be easily purchased at a low cost, but requires an assisted operation for each measurement, by the user or another person. This project proposed the development of a device capable of measuring blood oxygen saturation and heart rate. The data collected will be transmitted to a Smartphone, featuring an Android Application that displays the received data to the user and sends an automatic message to a health care center with the user's location in case of emergency. The project will also have sensors (accelerometers) to detect when the user has lost concience and fallen to the ground. This device will help to people with a history of health problems such as hypertension, hypoxia, risk of heart attack, among other diseases, giving them more autonomy, since in case of any health problems, somebody will be informed. The mobile monitoring of vital signals will detect when these signals vary significantly out of a safe range, and upon such occurrance a message is sent to pre-registered telephone numbers informing the user's location, and that he needs help help. The device will monitor the blood oxygen level and heart rate by measuring the change in the transparency of the blood through the presence of oxygen saturated hemoglobin is made. The measurement is taken by the emission of light at two wavelengths (red and infrared), where a sensor detects the intensity of light that is absorbed by hemoglobin, which depends on the degree of oxygen saturation. From the comparison between the received signals for each wavelength, it is possible to determine the degree of oxygen saturation in the blood. The meter is controlled by a microcontroller to be selected for this project. There will be a Bluetooth module connected to the microcontroller in order to establish the communication between the device and a paired Smartphone. An Android App will be developed to control the communicatin, display the user information sent by the device as well as send automatic voice messages to pre-registered telephones. The App will also reproduce additional messages played through the headphones to help the user in using the devices features, and also in case of emergency.

Overview The purpose of this document is to describe how to enable 3G modem in i.MX sabresx board for Android software. Hardware Changes Unlike other boards of I.mx series, in sabresx board  3G modem doesn't share to use PCIE slot any longer. It is not connected with PCIE slot by default. So if you still want to use 3G modem like in sabresd board. You need to do a tiny hardware rework. Like the below, R177 and R178 is DNP. Just add a zero resistor here. Software patches After you have do hardware rework above, then you should git am the attached patch to add software support which will add the dts config of 3G power. In our official release version, we don't include this patch.

These are my notes for compiling Qt 5.3.0 release using the fsl-community-bsp and the meta-qt5 layer graciously provided by the much lauded Otavio and Martin Jansa.  My test board is the wandboard solo.  My original procedure was based on this document: Compiling Qt5.3.0-beta1 on Yocto which was in turn based on this tutorial: Building Qt5 using yocto on Wandboard - Wandboard Wiki Steps to build: repo init -u https://github.com/Freescale/fsl-community-bsp-platform -b daisy; repo sync cd sources; git clone https://github.com/cetola/meta-qt5.git **as of this commit: https://github.com/meta-qt5/meta-qt5/commit/e9ad98bbed6065989ef4648e724f27275b35b838 the meta-qt5 official repo is now using qt 5.3.  I won't be updating my layer, and I suggesting using theirs. add to bblayers.conf:   ${BSPDIR}/sources/meta-openembedded/meta-ruby \   ${BSPDIR}/sources/meta-qt5 \ add to local.conf: DISTRO_FEATURES_remove = "x11 wayland" PACKAGECONFIG_append_pn-qtmultimedia = " gstreamer010 " bitbake wandboard-image-qt5 I will do my best to keep this working with the latest in daisy. Current functionality includes playing hardware accellerated video in QML.  However, examples such as multimediawidgets/player,  multimediawidgets/videowidget do not play video. Also qtwebkit/browser, qtwebkit/youtubeview qtwebkit/fanicybrowser do not support HTML5 video. Comments welcome. Cheers, Stephano
