使用esp-AT SDK烧录，发现程序一直在重启

[fst202130609]

我使用的esp32c3-mini-1，在网址上https://github.com/espressif/esp-at 把esp-at-2.3.0.0_esp32c3\examples\at_spi_master\spi\esp32_c_series这个工程编译下载之后，在串口调试助手log日志打印：

Hi,

您可以阅读一下 esp-at-2.3.0.0_esp32c3\examples\at_spi_master\spi\esp32_c_series 这个工程的 README.md，其中使用这个示例的硬件要求部分。以及如果您想要使用 SPI AT，该链接（https://docs.espressif.com/projects/esp ... spi#spi-at）的相关资料或许可以帮助到您

[fst202130609]

我不想用spi AT,我想用UART AT，有没有UART AT的SDK呢？

[ESP_Sun]

1. AT 工程默认配置就是 UART AT
2. 您可以先阅读下 AT 工程的文档，它可以帮助解决您在使用 AT 中遇到的大多数问题
- AT 工程文档：https://docs.espressif.com/projects/esp ... CN/latest/
- AT 工程：https://github.com/espressif/esp-at

[fst202130609]

AT默认的UART程序在main目录里？？

[ESP_Sun]

esp-at 工程默认配置就是使用 UART 通信接口，如果您编译时没有更改关于通信接口的配置，那么您现在编译的 esp-at 工程就是使用的 UART 通信接口

assertion "ret == ESP_OK" failed: file "../main/app_main.c", line 277, function: init_driver

严重错误：
DMA初始化错误， app_main.c 第277行。

猜测：
原始工程使用的是SPI总线挂载的外部扩展flash， 你的开发板没有。

您可以先跑通基本的 esp-at 工程的编译和 AT 命令，再基于这个加入您自己的代码。如果您遇到一些问题，烦请提供一下完整的可编译的复现的代码。
