原因已经找到，原来是Makefile 里面没有加入编译。
需要在./configure 配置 enable_deprecated 选项，这样生成Makefile的时候，才会加入hciattach 命令的相关编译。

下载到TF卡之后，发现文件系统是只读的，重新挂载之后也不行。

参看Tina Linux 存储介质切换：eMMC，SPI NAND，SPI NOR，SD Card，SD NAND 里面的spinor切换emmc 小节进行修改之后，现在系统是可读写的了。

1.目前开发板上面是使用的24M晶振。
2.在tina 里面配置（make menuconfig）的时候，取消XR829_40M固件的选项。查看make 的日志，也是复制的不带40M标号的固件到文件系统里面。
3.使用之前下载的longan-sdk 验证过硬件是没有问题的，能够联网。
4.目前发现问题在于get 每次增加到25553(试了几次这个数是固定的)之后就不会增加了，而put 还会继续增加导致后面就会报错。

static int xradio_firmware(struct xradio_common *hw_priv)
{

		for (i = 0; i < 100; i++) {
			APB_READ(DOWNLOAD_GET_REG, get);
			if ((put - get) <= (DOWNLOAD_FIFO_SIZE - DOWNLOAD_BLOCK_SIZE))
				break;
			mdelay(i);
		}
		xradio_dbg(XRADIO_DBG_WARN, "put:%d get :%d   %d: \n",  put,get,put -get);

		if ((put - get) > (DOWNLOAD_FIFO_SIZE - DOWNLOAD_BLOCK_SIZE)) {
			xradio_dbg(XRADIO_DBG_ERROR, "%s: Timeout waiting for FIFO.\n",
				   __func__);
			ret = -ETIMEDOUT;
			goto error;
		}
}

按照tina 文档打开XR829模块编译之后。在导入的时候报错。

感谢大佬，果然是longan-sdk 的BUG，换上tina 就好了。

@jr_online
仔细检查了一下设备树，发现 gpadc 没打开。
现在打开之后重新编译就能使用了。
感谢！

captain

@jr_online
请问一下修改那些地方能使用这个普通的 gpadc 呀？
我看它设备树里面都是配置的adc按键，不能直接去读取相关的adc值。
使用普通adc 命令就会报错。

单独使用时，每一路pwm都能够正常输出，但是同时开启多路PWM时，只有第一个被开启的有输出，后面开启的都没有输出。
