after configuring emmc boot_config and boot_bus_config and then booting from emmc with squashfs as root file system, the device will not boot a second time. Is squashfs some how resetting these two config values? It works fine with a sdcard.

Linux 3.14.28

Hi,

I also need a squashfs file system, but I do not know how to make it. Where did you get squashfs? 

Thanks!

Hi Yiling,

If your building your image via Yocto, add this to your local.conf file

IMAGE_FSTYPES += "squashfs"

HI Alric

one can read SRC_SBMR1,2 registers with jtag to check

if boot configuration is sampled correctly. To perform correct reboot second time

all board should be reset, including pmic.  Is it working with nxp linux describing in

i.MX 6 / i.MX 7 Series Software and Development Tool|NXP 

If not all board reset, squashfs may some how leave some board components in state

which affect boot.

Best regards
igor

Thanks for getting back Igor

I added an init script to set boot_config and boot_bus_config on each boot, this took care of the issue, 

I'll look into the  SRC_SBMR1,2 registers values, need to get the jtag setup.

Thanks,

amf
