I do not understand how this happened, but I rewritten the preloader and uboot. Now I have an uboot prompt like “MT7623>”
I tried to flash Openwrt through tftp, but when I restart, I see:
mmc0 is current device mmc0 operation dev_num = 0 MMC read: dev # 0, block # 2560, count 1 ... 1 blocks read: OK [do_read_image_blks]Bad Magic Number = 0x27051956 mmc0 operation serious check Bad Data CRC bootm flag=0, states=70f ## Booting kernel from Legacy Image at 84000000 ...

How I can to flash latest uboot?
