用JLink调板,之前都好用,今天一早连接以后PC无法识别USB,之后搜了一下,重新刷了下固件。现在能识别了,但是要烧写U-boot的时候,出现错误提示:
JTAG Timeout during adaptive clocking:RTCK did not respond .
Could not find supported CPU core on JTAG chain
Failed to connect
Could not programme target,not connected.
是肿么回事啊~是跟我重刷固件有关么?板子用的是ARM9261
刷固件后,update了吗?
当然也有可能是固件不匹配 升级一下固件吧
