MX6D hangs randomly on back-to-back reboot test with Android JB4.3_1.1.0 BSP

Hi all,

We are developing a system using MX6D (silicon rev 1.2) with Android JB4.3_1.1.0 BSP.

The system uses an 8bit eMMC as a boot source.

It has been looked working fine so far. But when we do a back-to-back reboot testing ( around 1sec term ), it hangs with the following message.

It happens at very different locations and with different oops messages whenever the system hangs.

Do you guys have any suspicicous things on it?

Thanks in advance so much!

Hi Yong

errors at different locations may mean

DDR errors, may be useful to update calibration coefficients

with links below

https://community.freescale.com/message/331721#331721

https://community.freescale.com/docs/DOC-96412

Just for test one can try to boot with lower frequency using fuse

BT_FREQ (BOOT_CFG3[2]) and increase pause between boots.

This may check if problem is related to power supplies (poor filtering, noise)

problems.

Best regards

chip
