如何使用esptool将tasmota (或任何内容)刷新到M5Stack ATOM Lite (ESP32-PICO-D4)？

Question

我已经尝试了这么多方法，但是使用esptool将固件刷新到M5Stack ATOM Lite ESP32开发工具包的正确方法是什么？它基本上是一个ESP32-PICO-D4。这(在许多其他命令中)不起作用：

> esptool.py --chip auto --port /dev/ttyUSB0 --baud 115200 --before
> default_reset --after hard_reset write_flash -z --flash_mode dio
> --flash_freq 40m --flash_size detect 0x1000 ~/Downloads/tasmota32.bin

闪烁成功，但当我看着arduino IDE的串行监视器时，我一遍又一遍地看着

当我使用ESP32- Pico -D4板的时候，我意识到它在技术上是不一样的。M5Stamp -PICO-D4也使用esp32-PICO-d4。尽管如此，也许这会有所帮助。这里的MACs都换成了零。

我使用下面的命令在Windows上成功地将ESP32 MicroPython固件刷新到主板上，并且运行正常。我使用的是https://micropython.org/download/esp32/最新的ESP32通用固件v1.17。

esptool.py --chip esp32 --port com6 --baud 115200 write_flash --flash_size detect 0x1000 esp32-20210902-v1.17.bin

这就是说，虽然上面的东西确实响应了你的“或任何”请求，但我抓起了第二个M5Stamp，并尝试了Tasmota。

我从他们的存储库下载了ESP32文件到一个文件夹：https://github.com/tasmota/install/tree/main/static/esp32

还将Tasmota32固件下载到相同的文件夹：http://ota.tasmota.com/tasmota32/release/tasmota32.bin

然后，我从下面的页面使用他们提供的命令，只需将COM端口更改为我正确的端口COM6：

https://tasmota.github.io/docs/ESP32/

使用esptool.py~需要esptool.py 3.1来识别新的电除尘器芯片。

对于esptool.py，使用以下命令语法(替换COM端口号！)：

C:\temp\tasmota>esptool.py --chip esp32 --port COM6 --baud 115200 --before default_reset --after hard_reset write_flash -z --flash_mode dout --flash_freq 40m --flash_size detect 0x1000 bootloader_dout_40m.bin 0x8000 partitions.bin 0xe000 boot_app0.bin 0x10000 tasmota32.bin

以115200bps的速度连接到COM6上的控制台时，我得到了一条指示成功的输出。我用手机查看了WiFi网络，看到了Tasmota SSID。我连接了，使用页面选择了我的网络，它正在工作，我怀疑它应该是。
