Can not boot from android_jb4.2.2_1.0.0-ga_image_6qsabresd/eMMC because of suspending console.

[cloudwu]

Hi,

      I have a freescale iMX6Q-SD board and want to boot it in Android OS.

I download the DEMO image (android_jb4.2.2_1.0.0-ga_image_6qsabresd/eMMC) and boot from eMMC.

I download the image by MFGtools and it succeeds. (boot.img, system.img, recovery.img, u-boot-6q.bin)

When I boot from eMMC (Sandisk), there may be something wrong and no any thing display on HDMI monitor.

Attached file is the log when I boot the kernel.

The u-boot parameter is show:

Hi Dan,

      I deeply appreciate your help. It works now.

My bootargs setting is

bootargs=console=ttymxc0,115200 init=/init video=mxcfb0:dev=hdmi,1920x1080@30,if=RGB24,bpp=32 video=mxcfb1:off video=mxcfb2:off fbmem=20M vmalloc=400M androidboot.console=ttymxc0 androidboot.hardware=freescale

The HDMI monitor can display the "android" logo.

But I still have the same problem.

ehci_fsl_bus_resume begins, Host 1

ehci_fsl_bus_resume ends, Host 1

ehci_fsl_bus_resume begins, DR

Suspending console(s) (use no_console_suspend to debug)

The system still enter sleep mode.

Do you know how to modify the sleep time?

Should I modify kernel and re-build it?

Thanks for your reply.

Hi Cloud,

There's no need to modify the kernel and re-build it, the only thing you have to do is to modify the sleep time. When the board is boot up and android is running, you can modify the sleep time in the setting option.

Have a great day~~

Best Regards

Dan

Hi Dan,

       Thanks for your reply.

I still cannot work now. After the system boot up and Monitor show "android" logo, it will suspend in serveral second later.

I don't make sure how to set sleep time in the setting option.

There is no board in my hand now. I will try after I get it again.

Anyway, thanks for your help.

Best Regards,

Cloud

Hi Cloud,

When the android is running on your board, you can modify the sleep time in the setting option. This option is as our IPAD or iPhone.

When you have board aside, if problem still exists contact me.  Once you give me reply  I can receive.

Hi Cloud,

How do set your u-boot?

Best Regards

Hi Dan,

     I connect the uart serial port and using a terminal application (ex. Teraterm).

The uart console can send command to u-boot.

My u-boot setting is :

MX6Q SABRESD U-Boot > printenv

bootdelay=3

baudrate=115200

ipaddr=192.168.1.103

serverip=192.168.1.101

netmask=255.255.255.0

loadaddr=0x10800000

rd_loadaddr=0x11000000

netdev=eth0

ethprime=FEC0

fastboot_dev=mmc3

bootcmd=booti mmc3

splashimage=0x30000000

splashpos=m,m

lvds_num=1

ethact=FEC0

stdin=serial

stdout=serial

stderr=serial

Hi Cloud,

I have seen your boot.log file, and I can see that the android system is running on your board. As the sleep time is too short by default setting so when your board boot up and then quickly go to sleep mode. The good method to  the avoid this is to modify the sleep time when your board boot up.  Also the default display is LVDS, so if you want to display on HDMI you have to set the u-boot first.

Best Regards

Dan

Hi Cloud,

I have tried with display on HDMI, as u-boot environment settings are  as below:

MX6Q SABRESD U-Boot > print

bootdelay=3

baudrate=115200

ipaddr=192.168.1.103

serverip=192.168.1.101

netmask=255.255.255.0

loadaddr=0x10800000

rd_loadaddr=0x11000000

netdev=eth0

ethprime=FEC0

splashimage=0x30000000

splashpos=m,m

lvds_num=1

fastboot_dev=mmc3

bootcmd=booti mmc3

ethact=FEC0

bootargs=console=ttymxc0,115200 init=/init video=mxcfb0:dev=hdmi,1920x1080M@60 video=mxcfb1:off video=mxcfb2:off fbmem=10M vmalloc=400M androidboot.console=ttymxc0 androidboot.hardware=freescale

stdin=serial

stdout=serial

stderr=serial

Environment size: 496/8188 bytes

Would you please try to set your display on HDMI as I attached above? Any questions contact me.

Best Regards

Dan
