原机ttl uboot启动是这样的
U-Boot 1.1.3 (Jan 9 2014 - 00:28:47)
Board: Ralink APSoC DRAM: 64 MB
relocate_code Pointer at: 83fb4000
enable ephy clock...done. rf reg 29 = 5
SSC disabled.
find flash: W25Q64BV
raspi_read: from:30000 len:1000
============================================
Ralink UBoot Version: 4.1.1.0
--------------------------------------------
ASIC 7620_MP (Port5<->None)
DRAM component: 512 Mbits DDR, width 16
DRAM bus: 16 bit
Total memory: 64 MBytes
Flash component: SPI Flash
Date:Jan 9 2014 Time:00:28:47
============================================
icache: sets:512, ways:4, linesz:32 ,total:65536
dcache: sets:256, ways:4, linesz:32 ,total:32768
##### The CPU freq = 580 MHZ ####
estimate memory size =64 Mbytes
Please choose the operation:
1: Load system code to SDRAM via TFTP.
2: Load system code then write to Flash via TFTP.
3: Boot system code via Flash (default).
4: Entr boot command line interface.
7: Load Boot Loader code then write to Flash via Serial.
9: Load Boot Loader code then write to Flash via TFTP.
