小白救砖第一季

tige***

入手2个K2 白来的。一个刷的A大的官改，另外一个开始吓折腾 折腾 折腾就成砖来了。红灯常亮，没办法只能试验TTL救砖。
第一天 折腾了一个下午也没救回来 不知道问题出在什么地方 望各路大神 大仙 指点指点

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.
