可能是因为我用的usb转串口工具ch340不支持921600的波特率
yuanjia,
你这个是在烧写的过程中,需要resetCC3100,让它处于UART的bootloader状态,但是uniflash应该是没有收到CC3100传回来的ACK信号。
所以你需要确定一下,在烧写时提示你restart device时,有没有正确操作reset按钮,或是系统有没有真正的reset。
谢谢
正确的reset操作是什么呢,我按了CC3100模块上的RST键的,不管用,我就把线拨掉也不行,怎么解决
是因为CH340的波特率达不到的问题吗,买一个FTDI怎么样?
你好:
我也遇到你的那个错误。你是怎么解决的?
是因为波特率达不到的问题,必须要921K的波特率才可以。
SPI_nHIB这个上拉没?
你好,请问你的这个问题是怎么解决的,我找了很久这问题,但是却一直找不到原因
