@whycan 我ssh用-i指定了文件，跟这个应该一样。然后按照你这个整了个配置文件，现象一样。

@whycan ubuntu也用ssh-keygen生成了密钥，就是这个现象。

@whycan 这个就是板卡，自动生成了dropbear_rsa_host_key，在/etc/dropbear下

@whycan 尝试过，也不行

@whycan 还是不行

@whycan 都试过，不行

@whycan 不行。我使用两块D1-H板卡，可以SSH连接，windows下使用SecureCRT SSH就不行。

@whycan 现在的key是自动生成了，在/etc/dropbear/下，dropbear_rsa_host_key，且试过不支持dss类型key，请问下具体key有什么问题，谢谢！

环境：D1H，Tina Linux2.0 SDK
操作：make menuconfig选择dropbear，编译打包生成的镜像，烧写到板卡后，windows下通过SecureCRT SSH连接不上（已经启动了dropbear）报错如下：

The client has disconnected from the server.  Reason:
The server's host key failed to verify.  This could mean that the server you are connected to is impersonating the server it claims to be. A connection could not be established. 

请教一下，有没有人碰到过这个问题，如何解决？

@whycanservice 选不选系统起来后都找不到SPI设备

@whycan kernel已经按照要求配置了SPIDEV，上面已经提到设置master模式是有设备的。你们可以拿开发板亲自试试按照文档设置slave模式能否出现spidev设备，给点实操可行的建议，谢谢！

@whycan 就是参考这个文档，但关键的是dts设置slave模式后，就没有spidev设备，示例代码没法用

请问Tina Linux 5.4环境下，spi1的slave模式应该如何使用？参考Linux SPI开发指南，修改dts

&spi1 {
	clock-frequency = <100000000>;
	pinctrl-0 = <&spi1_pins_a &spi1_pins_b>;
	pinctrl-1 = <&spi1_pins_c>;
	pinctrl-names = "default", "sleep";
	spi_slave_mode = <1>;
	spi1_cs_number = <1>;
	spi1_cs_bitmap = <1>;
	status = "okay";

	spi_board1@0 {
		device_type = "spi_board1";
		compatible = "rohm,dh2228fv";
		spi-max-frequency = <0x5f5e100>;
		reg = <0x0>;
		spi-rx-bus-width = <0x1>;
		spi-tx-bus-width = <0x1>;
		status = "okay";
	};

};

无spidev设备生成，文档slave参考示例没法用

@whycan 能link，去掉br-lan后可通。目前出现uboot下tftp无法传输文件，提示超时，uboot下ping主机时通时不通，不稳定，大佬指点下，谢谢！

@whycan 配置的静态ip

官网下载的Tina SDK，直接编译生成的镜像，烧写完系统启动后eth0无法同主机ping通，请问可能是什么原因？
