将ESP-01S刷入较新的AT固件，如何让最新的稳定固件工作并响应AT命令？

问答对人有帮助，内容完整，我也想知道答案 0 在过去的两天里，我试图将最新的 AT 固件刷入我的 ESP-01S 模块，但没有成功。唯一成功运行的版本是带有“XTCOM_UtiL.exe”的 v.0.9.5.0，这是引导期间 74880 波特的控制台：代码：全选 ets Jan 8 2013,rst cause:2, boot mode:(3,7) load 0x40100000, len 612, room 16 tail chksum 0x12 load 0x3ffe8000, len 788, room 4 tail 0 chksum 0x50 load 0x3ffe8314, len 264, room 8 tail 0 chksum 0x4a csum 0x4a 2nd boot version : 1.1 SPI Speed : 40MHz SPI Mode : QIO SPI Flash Size : 4Mbit jump to run user1 之后它以 9600 波特率成功响应 AT 命令。我知道 v.0.9.5.0 有一些错误，我在我的项目中遇到了其中一个，这就是为什么我需要一个更新的版本。我从这里下载了“ESP8266 IDF AT Bin V2.0” ，并使用 esptool.py 使用 download.config 中的命令对其进行了刷新：代码：全选C:\Users\user\.windows-build-tools\python27\Scripts>esptool.exe --port COM2 write_flash --flash_mode dio --flash_freq 40m --flash_size 1MB 0x9000 ota_data_initial.bin 0x0000 bootloader/bootloader.bin 0xBF000 at_customize.bin 0xC0000 customized_partitions/factory_param.bin 0xC1000 customized_partitions/server_cert.bin 0xC3000 customized_partitions/server_key.bin 0xC5000 customized_partitions/server_ca.bin 0xC7000 customized_partitions/client_cert.bin 0xC9000 customized_partitions/client_key.bin 0xCB000 customized_partitions/client_ca.bin 0x10000 esp-at.bin 0x8000 partitions_at.bin esptool.py v2.8 Serial port COM2 Connecting....
