If Android device has Internet access, it can download and install TTS library automatically. However, sometimes in a developer environment, Internet may not be available. Download TTS library from Eyes-Free project, [1] Unzip all files into VFAT partition (of SDCard).

Question: After a JTAG Reset with his GHS MULTI Probe on i.MX6 Hardware, read the SRC_SRSR register the corresponding reset source bits (JTAG reset) are not set. The contents: SRSR = 0x1      WARM Boot = 0x0      jtag_sw_rst = 0x0      jtag_rst_b = 0x0      wdog_sw_rst = 0x0      ipp_user_reset_b = 0x0      cpu_reset_b = 0x0      ipp_reset_b = 0x1 Tried to reproduce this with my DSTRAM probe, and issued a "reset reset.system" command in DS-5 Debugger but Program Counter stays at current vaule. Obviously my SRSR bits don't change either. Answer: Seems " jtag_rst_b" is a HW reset, please check the connection between JTAG port and i.Mx6 JTAG_TRST pin. And confirm the waveform on rest pin when JTAG reset run.

Recently many customers faced the issue about connecting the git.freesacle .com failed when they built old bsp version like 4.1.15 or 3.14.52,  when the customer repo init according to the yocto user guide, they get the error message like ： repo init -u git://git.freescale.com/imx/fsl-arm-yocto-bsp.git -b imx-4.1-krogoth manifests:  escale.com[0: 192.88.156.202]: errno=Connection refused  fatal: cannot obtain manifest git://git.freescale.com/imx/fsl-arm-yocto-bsp.git ///// git clone git://git.freescale.com:9418/imx/fsl-arm-yocto-bsp.git -b imx-4.1.15-1.0.0_ga Cloning into 'fsl-arm-yocto-bsp'... fatal: unable to connect to git.freescale.com: git.freescale.com[0: 192.88.156.202]: errno=Connection refused the reason is that the old bsp source code was moved to "https://source.codeaurora.org/external/imx", customer needs to change "git://git.freescale.com/imx"  to "https://source.codeaurora.org/external/imx", for new repo init commands, try to use the commands like “repo init -u https://source.codeaurora.org/external/imx/fsl-arm-yocto-bsp -b <branch> [-m <manifest>]” for example: 4.1.15_1.0.0: repo init -u https://source.codeaurora.org/external/imx/fsl-arm-yocto-bsp -b imx-4.1.15-1.0.0_ga 4.1.15_2.0.0: repo init -u https://source.codeaurora.org/external/imx/fsl-arm-yocto-bsp -b imx-4.1-krogoth -m imx-4.1.15-2.0.0.xml 4.1.15_2.1.1: repo init -u https://source.codeaurora.org/external/imx/fsl-arm-yocto-bsp -b imx-4.1-krogoth -m imx-4.1.15-2.1.1.xml then you can "repo sync" and "bitbake", but some customers still has the connection error on building firmware-imx package, the error message like : ERROR: firmware-imx-1_5.4-r0 do_fetch: Fetcher failure: Fetch command failed with exit code 128, output: Cloning into bare repository '/opt/yocto/fsl-release-bsp/downloads//git2/git.freescale.com.imx.imx-firmware.git'... fatal: unable to connect to git.freescale.com: git.freescale.com[0: 192.88.156.202]: errno=Connection refused ERROR: firmware-imx-1_5.4-r0 do_fetch: Function failed: Fetcher failure for URL: 'git://git.freescale.com/imx/imx-firmware.git;branch=master;destsuffix=/opt/yocto/fsl-release-bsp/fsl_build_x11/tmp/work/cortexa9hf-neon-mx6qdl-poky-linux-gnueabi/firmware-imx/1_5.4-r0/firmware-imx-5.4/git'.

Instead to use gst-launch to play your audio/video media you can create an application do to that. This application was tested in iMX27ADS but should to work on iMX27PDK First execute LTIB (./ltib -c) and select these packages: all gstreamer plugin, alsa-utils and libmad.

It is suggested to create a layer when creating or modifying any metadata file (recipe, configuration file or class). The main reason is simple: modularity. Follow these steps 1. To have access to Yocto scripts, setup the enviroment from the BASE folder fsl-community-bsp $ . setup-environment build 2. Move to the place you want to create your layer and choose a name (e.g. `fsl-custom`) sources $ yocto-layer create fsl-custom # Answer the questions. Make sure the priority is set correctly (higher numbers, # higher priorities). Set the priority equal to the lowest already present, except # when you have introduce a new recipe with the same name as other and want to shadow # the original one. 3. Add any metadata content. Suggestion: Version the layer with Git and upload your local git repo to a server 4. Edit and add the layer to the `build/conf/bblayers.conf` file 5. To verify that your layer is *seen* by BitBake, run the following command under the build folder build $ bitbake-layers show-layers This document was generated from the following discussion: i.MX Yocto Proyect: How can I create a new Layer?

Q: Does VIN have to be valid before we can talk to the PMIC over i2c? Can a valid voltage on LICELL and VDDIO work instead? The PF0100 datasheet says: ---------------------------------------------- To communicate with I2C, VIN must be valid and VDDIO, to which SDA and SCL are pulled up, must be powered by a 1.7 to 3.6V supply. VIN, or the coin cell voltage must be valid to maintain the contents of the registers. -------------------------------- A: VIN and VDDIO must be valid for communicating to the I2C block. Having LICELL and VDDIO will not work since a portion of the digital circuitry needed for accessing the registers is powered through VIN. This document was generated from the following discussion: Programming PMIC over i2c

Question: Is SN65LVDS315 (MIPI CSI-1) compatible with our i.MX6 MIPI CSI-2 interface? CSI-2 extends CSI-1 with multiple lanes, but both standards use the same D-PHY layer. Answer: No, the i.MX6 MIPI CSI-2 interface is not compatible with CSI-1 devices. Standards that require backward compatibility to legacy standards always state that the standards are backward compatible. The CSI-2 standard does not say that. (I have a copy of the standard and I have read it specfically for that reason)  The CSI-2 standard does say that a specifically designed PHY, built to D-PHY MIPI01 specification is used for CSI-2. The PHY's used for CSI-1 and CSI-2 are different and they are not compatible. There are some processors that do have compatiblity for CSI-1 and CSI-2, but if you read closer, you will find that they have two different modes (and probably two different sets of pins): One for CSI-2 and One for CSI-2/CSI-1 legacy. It is interesting that a company would choose to inlcude a dying technology in a newer processor, but my guess is that they have a number of other CSI-1 devices they are trying to sell before they can't be used anywhere and nobody wants them. if the customer is looking for a parallel camera interface to CSI-2 converter IC, may I recommend the Toshiba TC358746 device. I have not used it specifically, but I have worked with a Toshiba rep on an HDMI to MIPI CSI-2 project that input into the i.MX6 processor. Once all the correct parameters were determined, it worked very well. Much higher data rate flow.
