Hello,
I'm using a custom board, based on the START-R board, and I can succesfully start u-boot and kernel 2.6.35 on it. I load uImage, u-boot and initramfs on an sd-card, I send the boot command and then I see the output from the kernel, until it arrives at the message "feed watchdog", which is written periodically on the output. I would expect a serial console, like the one given by the quick start board...
Please, could anybody help me to find out what I could have missed?
Solved! Go to Solution.
I assumed that you are using ltib. So you can input the following command line:
./ltib -m selectype
Select as the followings:
│ │ --- Choose the platform type │ │
│ │ Selection (imx5x) ---> │ │
│ │ --- Choose the packages profile │ │
│ │ Selection (FSL gnome release package) --->
If you just want to try a minimum rootfs, you can select “Minimum bootable root filesystem”.
Then “Save” it. You can see another prompt menu. Select as the followings:
│--- Target System Configuration │ │
│ │ Options --->
You can see the followings:
│(freescale) target hostname │ │
│ │[*] boot up with a tty and login │ │
│ │(::respawn:/sbin/getty -L ttymxc0 115200 vt100)
You had better check your "console" setting into bootloader. And use the right console output.
Do you mean the console environment variable in u-boot? I've set it at console=ttymxc1, i.e. UART2, and I'm sure it works, because other messages from the kernel are correctly sent to this serial interface (e.g. the "feed watchdog" one).
So I guess you flash the ram rootfs for MFGTool instead of the normal rootfs for booting.
Please flash the right default rootfs.
Thank you for your answer, after compiling and depoloying I load these files onto sd-card for booting:
ltib/rootfs/boot/u-boot.bin
ltib/rootfs/boot/uImage
ltib/initramfs.cpio.gz.uboot.
If the latter is not the right initramfs where should I find the right one?
