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,

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