Can't SD boot on ultrascale Zynq

[ransh]

Hello,

I have difficulties booting zynq ultrascale with SD.

I use sandisk 16G SD.

I see in the following list that there is mention of sandisk 16G, so I am not sure why it does not boot.

Is it because only uhs-1 should be used instead of non-uhs ?

The list I found is here:

Thank you,

What do you see when you try boot? Is there anything displayed on the serial port?

Also, does the init_b constantly toggle. This would tell you that the boot rom is looping for the boot image

Hi Stephen,

For now, we decided to leave aside the sd boot, because we can boot from jtag.

Thank you very much,
