nachodiz · ‎04-27-2017

Dear all, we´re trying to bring out board to life (for an important Automotive Customer)

I´tried to connect through serial downloader (USB) and it hangs when Loading Uboot

We also have UART pads Just in case for debug

My intention it´s to copy the i.MX6UL-EVK Fuses but changuing the SD2 boot device from SD1 (we have the sd on the SD1 bus)

Who can help us with this process, STEPS....
I want to perform a DDR Test

King Regards

Hello,

Looks like the MFG system (U-boot, kernel, ramfs) can be loaded (maybe successfully ),

but cannot start, since reset takes place. This may be memory bug. Please try the DDR stress test.

Have a great day,

Yuri

Hello,

My i.MX6UL-EVK board has meet the same problem like the video , and I try the DDR stress test but failed.

The board is working correctly before , but yesterday it suddenly unable to work.

How can I solve the problem or How can I test the board to determine that whether the board is dead?

Thanks a lot for your help.
