I'm not really familiar with the boot procedure on mt7621, but at least to my eyes, it looks like you'd have a problem with your bootloader - way before anything OpenWrt related would happen.

Those are the last messages you should get from the bootloader, before the flashed firmware (kernel+rootfs) takes over. It appears as if you had somehow damaged parts of the bootloader.

Why are you deleting your posts?

For recreate a new with the solution found after remove flash eeprom 32 pins and add a 8 pins SPI 16MB W25Q128

Also i cannot edit first msg

Should be MB instead of pins?

12

Yes : 8 pins & 16 MB ( edited )
