Hi Stefan,
Why did you take the value 0x20 in the table entry instead of the value 0x00 as it is, for example, in the NXP U-Boot?
0x00 would mean b0000, which is WEIM (OneNAND/NOR flash, which is probably a likely boot device).
0x20 is no defined boot device, and since it works, it will make sure that bmode usb works for all users of i.MX 6UL/ULL...

Is it because this boot mode does not exist in the iMX6UL SOC?

i.MX 6UL and 6ULL have different boot device capabilities and use therefor use a different boot device selection table than other i.MX 6 devices. Particularly, the value which has been used so far (b0001) is assigned to QSPI boot for these two devices.
There is no common reserved value for all i.MX 6devices. Use b0010 for i.MX 6UL and 6ULL via compile time ifdef.
