This issue is also happening with i.MX6ULL, seems that padding the
U-Boot binary to the size defined in boot data is addressing this
issue.

Please follow example below.

1. Dump boot data:

$ hexdump u-boot-dtb.imx | head
0000000 00d1 4020 0000 8780 0000 0000 f42c 877f
0000010 f420 877f f400 877f 6000 878d 0000 0000
0000020 f000 877f b000 000d 0000 0000 01d2 40e8
0000030 01cc 04e4 0c02 6840 ffff ffff 0c02 6c40

IVT self = 0x877ff400
Boot data addr = 0x877ff000
Boot data size = 0x000db000

2. Calculate image size:

Image offset = IVT self(0x877ff400) - Boot data addr(0x877ff000) = 0x400
Total image size = Boot data size(0x000db000) - Image offset(0x400) = 0xdac00

3. Pad U-Boot image:

$ objcopy -I binary -O binary --pad-to 0xdac00 --gap-fill=0x00
u-boot-dtb.imx u-boot-dtb.imx.pad

Could you please try similar in your i.MX7D board?

Thanks,
