MT7628 do not write firmware

I created U-boot from Padavan sources.

My hardware for test is:
GL.iNet GL-MT300N V2

128MB = 1024Mb
MTK MT7628NN @580Mhz SoC

When I uploading the original firmware, true HTML, is written.

openwrt-mt300n-v2-3.211-1227.bin 12MB

When I upload my version of OpenWRT it is not written.

openwrt-ramips-mt76x8-glinet_gl-mt300n-v2-squashfs-sysupgrade.bin 4.8MB

Build is OpenWRT v21.02.2
Targhet -> Ralink MIPS
Subtarghet-> MT76x8
Profile->GL.iNet GL-MT300N V2

No other change to config.

can someone help me ?
