When the U-Boot prompt appears: => Type the command to transfer the u-boot.bin binary: => loady Then press the combination keys: Ctrl+a s Then select the option: ymodem A text mode "file explorer" will appear. Select the desired binary (u-boot.bin) pressing "Space" key. The file transfer will start. To execute the uploaded file just issue: => go 0x100000 Replace 0x100000 with your TEXT_BASE address.

Why reset EPDC When TCE underrun occurs repeatedly, EPDC might lock up and the signal to panel continues. There is chance to cause panel damage. The attached patch provides a way to reset EPDC to cut the signal out and recover EPDC from lockup. The patch is based on L4.1.15. As for TCE underrun, QoS patch has obvious improvement. https://community.nxp.com/docs/DOC-343599

A discussion of random hangs and other issues using Windows Embedded Compact on Freescale i.MX6 application processor and how they were solved. This white paper is about the investigation and shares some of our discoveries. All information in this document applies to Windows Embedded Compact 7 and 2013 as well as all variants of the i.MX6.    

These instructions used ltib-imx27ads-20071219. First, get u-boot v2.0: git clone http://git.denx.de/u-boot-v2.git u-boot-v2 Enter the U-Boot directory: cd u-boot-v2 Export the proper compilation paths and environment variables: export ARCH=arm export PATH="$PATH:/opt/freescale/usr/local/gcc-4.1.2-glibc-2.5-nptl-3/arm-none-linux-gnueabi/bin/" export CROSS_COMPILE=arm-none-linux-gnueabi- Configure it for the i.MX27ADS board: make mx27ads_defconfig You may want to enable the FEC driver: make menuconfig And go to Drivers -> Network drivers and select Yes on i.MX FEC Ethernet driver Exit the config menu (don't forget to save the configuration) and just make it: make Or if you prefer the verbose mode make V=1 After a quick build, you should get a uboot.bin on your current directory. I used the ADS Toolkit to program the NOR flash.

I followed the Yocto Training up until Task #4 - Deploy and test.... and I got stuck here. I am not able to download the .sdcard image to my SD card. Do I need to format it first? It is brand new. Since the sudo dd if=core-image-base-imx6solosabresd.sdcard of=/dev/sdb1 bs=1M did not work for me, I was not able to boot from the SD on my board. The board switches are set to boot from SD4. Is imx6solosabresd the correct MACHINE to use for the solox? I tried setting MACHINE=imx6sxsabersd in the local.conf file but I got an error message (Task #2). This is why I want to try the MFGTool. I have set the board to boot from SD3 so it can go into "download mode". When I go through the MFGTool, it says No Device Connected although HID-compliant vendor-defined device shows up.

Dear,   We want to start application program from bootloader, we have below questions: We we use I.MX6UL bootrom start BootLoader， we need use mkimage.sh, compile and generator bin file, then we convert to executable file. If we need use Bootloader run application program,whether application image also need convert by mkimage.sh?  The file which convert by mkimage.sh is compressed file. we do not know its format, how about its start address, how to realize the the address jump, do you have example? Thanks.

The imx_bootlets package in LTIB contains the code that will be the first code loaded and executed by ROM when booting a build of the Linux BSP. It is responsible for initializing some of the low level peripherals such as the integrated power supply and the DRAM controller as well as a few other initialization tasks. The default configuration of the bootlet code for the latest i.MX233 and i.MX28x release (SDK 10.05 and SDK 10.12 respectively) support a hardware configuration that has both a LiIon battery configuration (as shown in the reference schematics for these platforms as shown on freescale.com). For other configurations though such as a VDD5V connection only or a DCDC_BATT/Battery connection only, some additional changes are recommended.

i.MX27 and i.MX31 Issues When Interfacing Micron's 78nm mDDRs Micron is discontinuing some "-75" mDDR parts (133MHz) popular on i.MX27 and i.MX31 designs, newer "-6" are being used to replace the EOL devices. However, loss of data issues may be experienced when i.MX mDDR controller is used to interface with newer Micron's mDDR. On some cases, the bootloader works, memory tests on RedBoot pass. However, Linux hangs when booting. Here are the DDR Controller configuration changes that may be used to avoid the issue: (This configuration is not proven to work on every design, but has been validated on at least 3 different boards.)

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.
