TL-WR941N刷DD-WRT固件体验全过程

-------------------------------------------------------------------- TTL线刷过程： -------------------------------------------------------------------- 一、准备软件 1、任意使用串口助手工具AccessPort、SecureCRT等，将波特率设置为115200； 2、tftp服务软件tftpd32.exe，将固件wr941v4_100723.bin放在服务软件目录或设置为固件目录； 二、准备硬件 1、使用自制串口-TTL模块，IC为旧电脑MAX202CPE。最好使用带串口的电脑，硬串口数据稳定，系统为XP。无条件可以购买USB-TTL转接线。 2、在TL-WR941N V4主板JP2上，从JP2依次为TX-，RX+，GND，V+，焊接上旧电脑主板上拆下的3针跳线，从JP2处焊接3针，V+不需要接。 三、开始TTL刷固件， 1、打开串口助手工具，波特率115200 2、串口连接RS232-TTL模块，TTL的TX-，RX+，GND插口依次插在WR941主板的自接插针上，WR941_V4接上外节电源，观察串口助手窗口，如果出现反复如下数据，即可。否则可能是TX-，RX+接反，交换插即可。 ------------------------------------------------------------------- U-Boot 1.1.4 (Apr 12 2013 - 19:34:20) AP93 (ar7240) U-boot DRAM: sri #### TAP VALUE 1 = 8, 2 = 8 32 MB id read 0x100000ff flash size 4194304, sector count = 64 Flash: 4 MB Using default environment In: serial Out: serial Err: serial Net: ag7240_enet_initialize...
