Hi. We are using iMX6 SABRESD board with ltib-4.1.0. We need blit functionality for OpenGL framebuffer objects. It is present in OpenGL GL_EXT_framebuffer_blit extension, but is missing on iMX6. We use QOpenGLFramebufferObject class from Qt. There is blitFramebuffer() method that was working fine on desktop and Android devices. Its method hasOpenGLFramebufferBlit() returns false on iMX6 which means extension is not present. As expected, blitFramebuffer() itself is not working (screen remains black). We need this extension enabled. Why is it missing on iMX6 and is it possible to add it? Regards, Federico

iWave, a reliable embedded solutions provider has now optimized the booting time of its Windows Embedded Compact 7 (WEC7) BSP for Freescale’s SABRE SDP/B platform. Now the WEC7 OS is booting in a short period of time  ~3 seconds for a small footprint OS image with display and touch drivers support, and boot time of ~8 to ~10 seconds for an OS image with basic drivers and OS components support. Why boot time optimization? WinCE7 is a real time OS which will be used in performance-critical applications such as automotive and healthcare units. In most of the cases, booting time will play important role, e.g. if the device is used in rear-view camera system in automotive field, the user needs the device to start working as soon as the reverse-gear is applied. This requirement needs the device to boot and start the camera application within few seconds. This demands a very short OS boot time. Some of the techniques which can be applied for efficient boot time optimization are discussed in this article. Boot phases in WEC7: Boot-loader (eboot) Copying of OS image from booting device (e.g. Micro-SD) to RAM OAL Layer Driver initializations and file system mounting Guidelines for reducing the boot time in different booting phases of WEC7: Boot-loader (eboot): Remove the code that initializes a hardware which is not required in boot-loader. E.g. If booting device is micro-SD, the initialization of NAND is not necessary. So, this redundant code needs to be removed. The eboot menu in eboot is important for debugging of WEC7 OS. But it is not needed in an end product. So, the delay for this eboot menu can be completely removed to reduce 3 seconds of time. In few platforms such as Freescale’s SABRE platform, a default splash screen is used, which updates continuously. This can be removed, and a static splash screen can be displayed, which can save a few milliseconds of time. Remove unnecessary serial debug prints. Copying of OS image from booting device (e.g. Micro-SD) to RAM: This time increases as the size of WEC7 OS image increases. So, select the OS components carefully and remove redundant components from OS image so that the OS image can be copied to RAM quickly. Also remove unnecessary registry keys, dlls and libraries to reduce the OS size. Optimize binary image builder (.bib) file to reduce the run-time image file. Implement Multi-BinFS OS binaries to reduce the OS copying size. As the functionalities/driver supports goes on increasing, WEC7 image size increases. So, the time required to copy the image increases, and RAM size needed to store the OS image increases. The Binary ROM Image File System (BinFS) can fix the two issues. In a BinFS file system, the WEC7 OS binary is divided into multi-binary Image files, and only the one binary (less than 5MBs) is copied into the RAM by the boot-loader. The components in the other binary files are copied into the RAM only when they are required to run. Links that can be referred to implement multi-BinFS in WinCE:      MSDN documentation: http://msdn.microsoft.com/en-us/library/aa516960.aspx; An implementation guide by Freescale: http://cache.freescale.com/files/dsp/doc/app_note/AN4137.pdf You can also include compressing-decompressing mechanisms in boot-loader to achieve even shorter copying time. OAL layer: Remove the code that does unnecessary hardware implementations. Skip the initializations that already done in eboot. Remove any wait/loop/delay if exists. Remove unnecessary serial debug prints. Driver initializations and file system mounting: Analyse and remove all the redundant drivers, check for any loop, wait or delay sequences in driver initialization code. Load any applicable drivers (e.g. USB, sensors) after the OS boot (i.e. after user sees a desktop/application). In WEC7 OS, a driver can be either loaded during booting using device manager/GWES, or can be loaded dynamically whenever necessary. This can be achieved easily by changing the registry key configurations to remove the driver from built-in drivers, a small application to load the driver after OS boot-up, and registry settings to launch this application automatically once the OS is booted. To decide the load order, it is important to check the dependencies of/on a driver. Use appropriate splash screen/progress bar while user waits for OS booting. Remove unnecessary serial debug prints. By effectively following the techniques mentioned, WEC7 based platforms can achieve reduced boot time for quick application access. iWave has optimized the WEC7 booting time on Freescale’s SABRE SDP platform. The booting time is as low as ~3 seconds for a WEC7 OS with standard shell, LCD display, DDraw, I2C and touch driver support, and ~8 to 10 seconds for WEC7 OS with following components: Standard shell Display DDRAW Capacitive touch screen MicroSD USB host – Mass storage and HID Ethernet GPU (OpenVG/GL) Multimedia codecs DirectShow Audio Video Playback Ambient Light Sensor Accelerometer SMP PWM Backlight I2C Debugging using KITL For further information or inquiries please write to mktg@iwavesystems.com or visit www.iwavesystems.com

M2M Solution for Cellphone Tower Monitoring​ Customer Requirement: System to monitor several parameters such as, temperature, smoke, power source, door open, diesel level etc. in the cell phone tower and remotely monitor them through cloud. The system should monitor and raise alarm when the values exceeded the threshold limit; it should send a text message to the authorities. Challenges: The main challenge in designing the system started with the electrical & electronics and high noise with ESD & EMI signals. It was very important to design the system in such a way that it could interact with the sensors and at the same time, should not be affected by radiated or conducted electromagnetic disturbance. The system cable faced high ESD & EFT injections & the temperature had to be maintained under 25° to power up the system. Approach: e-con Systems designed an architecture based on eSOMiMX6 system on modules that is highly reliable. The system was proposed to extract the information about the tower & communicate the same with cloud. Amazon cloud based web services was used on the cloud side to monitor various parameters & to send the alerts. Base board implemented with eSOMiMX6 interacted with all sensors, collected the information and same would be transmitted via a GPRS unit or Ethernet or wireless unit. Depending on the availability, system selected one path & EMI/EMC/ESD events protected the path of information collection. Power saving modes was designed keeping in mind product power consumption & the total power used when running in diesel generator. The product was tested in-house with simulated tower environment for 2 weeks (24/7) continuously. All issues were identified and addressed. e-con Systems worked with the customers at all levels to get the necessary certification approval. Conclusion: Customer is now successfully selling the robust product in the market. The tower monitoring business is now highly profitable as breakdowns were brought down to nearly zero
