空芯片,未加SPI FLASH 显示 下载模式(IO15 10k下拉 , IO0下拉 (直接GND),IO2上拉(文档上说是有内部上拉的,先上拉)) ;en 重启(下拉 后悬空)输出
(io2同时有输出DEUG信息串口TX)

电路
VCC_RTC 是不连的
RES12K 12K电阻
复位脚 32 RST 与 en 脚 32可以空,EN复位 低电平
为了增加,减少复杂度,可以使用有源晶振 26M;(四脚无源无电容亦可)
错误:

奇怪了,下载模式正常

使用 FLASHDOWNLOAD V3.9.7就是无法下载,产生错误(用3.9.7下载,最后阶段最会出现错误,而用3.6的对正常模块却可以)

故意排除:上电无打印 虚焊,连线
3.3V GND 有源晶振26M
连线正常,电源不发热,芯片不发热,UART0(25 RX 26 TX)不输出;焊接,虚焊;
