Unknown values at the start of i.MX 8MM EVK's QSPI imx-boot

[kanimozhi_t]

Hi Team,

In i.MX 8M Mini EVK, we've generated the QSPI image by adding the configuration “UBOOT_CONFIG= fspi" in "local.conf" file.

As normal, the QSPI image address is started after 0x1000 address but in our image initial address having some (constant) value. The values shown in below screenshot:

1. Is this initial value normal?

2. If so, what are those?

3. If not, how can we remove/clean that?

Thanks in advance.
