你好!
请问按照8258的datasheet中提示的原理图,画的PCB(32pin),用WTCDB,发现不能RsetMCU/SWB,板上只焊了8258、晶振、电感和芯片相关电容,不知道怎么回事?有没有什么需要注意的?L1可以直接用0欧姆电阻短接吗?

你好,请在论坛上下载8258的烧录工具。目前是跟wtcdb区分开了。单独一个。

你好!
我已经下载8258了烧录工具“Telink Burning and Debugging Tool(BDT)”,用8266的EVK烧录,

原理图如上一个问题,还是提示错误,是不是原理图中有什么问题?

1、请接三根线到下载板上面。下载板SWM-----被烧录SWS, 下载板VCC-----被烧录VCC, 下载板GND-----被烧录GND。
2、可量测芯片周边电压对不对,电源电压,晶振电压等。可与开发板进行对比。
