Dear All,

I'm using the i.MX6S with eMMC and Android JB 4.3.

 

But the board was not booted in Low Temperature with below messages.

Could you give me any guidance for this issue?

For whole log message, refer to attached file.

 

** Can't read partition table on 3:0 **

booti: device don't have such partition:boot

fastboot is in init......flash target is MMC:3

** Can't read partition table on 3:0 **

Bad partition index:1 for partition:boot

** Can't read partition table on 3:0 **

Bad partition index:2 for partition:recovery

** Can't read partition table on 3:0 **

Bad partition index:5 for partition:system

wait usb cable into the connector!

 

Best Regards,

Eric.

Hi Eric

I would suggest to run SDK (it has block read/write test)

and check if issue will present. Failures at low temperatures

may mean that drive strength i.MX6 and eMMC pads is too strong,

one can try to decrease it, example can be found below

https://community.freescale.com/thread/332110

also one can try other eMMC, since these chips may differ in

its driver strength characteristics.

Best regards

igor
