  1. I will definitely give it a shot when I get my new SD card (I don't want to mess up the current one). But in the end, my SD will contain the following: /boot zImage imx6q-hummingboard.dtb /lib (obtained from make modules_install) uEnv.txt and of course the SPL and uboot. Does anything look suspicious to you? Thanks, Kam
  2. Thank you so much Igor! This solved my problems! Originally I was following the instructions here to get my image using another Linux machine. So I compiled the kernel and uboot image, then followed the instructions at the bottom to flash them into my SD card. However, the instructions seem to work only for uImage, but I got a zImage from compiling the 3.14 kernel, so I changed the first line of uEnv.txt to "bootfile=/boot/zImage", but that gave me a "Wrong Image Format for bootm command" when I tried it on hummingboard. I then did the following in uboot: setenv bootargs 'console=ttymxc0,115200 video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24,bpp=32' ext2load mmc 0:1 0x10800000 /boot/zImage bootz 0x10800000 But my screen just went black after the bootz command. I then tried converting the zImage to uImage by typing the following: mkimage -A arm -O linux -T kernel -C none -a 0x80008000 -e 0x80008000 -n "Linux kernel" -d arch/arm/boot/zImage uImage I tried to boot off that uImage and it gave me a black screen again. What am I doing wrong here? PS: From the instructions I followed, I did not do anything for following line because I wasn't sure what to do: <copy the root filesystem and do any other modifications on the mounted partition> ,but I doubt that's the reason?
  3. Hi Igor, I am working with the hummingboard and I am trying to use the g_mass_storage gadget by modprobing the driver. However, it seems like the Debian wheezy raw image I got from here does not have the USB OTG port configured in device mode. I saw from this post that we are able to change the id pin by changing the device tree file. My question is can I configure the USB OTG port to device mode on the fly or do I need to modify the device tree and recompile the kernel and uboot image myself. If so, what should I change from your scripts? Thanks, Kam
