求助自己打样的ESP8266烧录失败

Postby artint » Thu Apr 15, 2021 5:55 pm

自己按照Wemos D1 mini的原理图做了一块开发板,flash使用的是 https://item.szlcsc.com/730909.html 这款,其它元件和原理图的型号一致。焊好后启动报:
ets Jan 8 2013,rst cause:2, boot mode:(3,7)

ets_main.c


烧录一直失败,上电同步超时:


Executable segment sizes:
IROM : 228624 - code in flash (default or ICACHE_FLASH_ATTR)
IRAM : 26756 / 32768 - code in IRAM (ICACHE_RAM_ATTR, ISRs...)
DATA : 1248 ) - initialized variables (global, static) in RAM/HEAP
RODATA : 688 ) / 81920 - constants (global, static) in RAM/HEAP
BSS : 24880 ) - zeroed variables (global, static) in RAM/HEAP
项目使用了 257316 字节,占用了 (24%) 程序存储空间。最大为 1044464 字节。
全局变量使用了26816字节,(32%)的动态内存,余留55104字节局部变量。最大为81920字节。

尝试过不同的开发板设置和Flash Mode也不行,有什么头绪么?

找块官方模组对比试试看呢?如果官方模组可以,你的不可以,那可能就是硬件问题;如果官方模组和你的模组都不可以,那可能就是你操作或者用的工具之类的有问题。
