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。

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。

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。

按照一下命令进行操作pwm,输出的pwm波形如图。
正常情况下，应该输出方波才对。

echo N > /sys/class/pwm/pwmchip0/export
echo 1000000 > /sys/class/pwm/pwmchip0/pwmN/period
echo 500000 > /sys/class/pwm/pwmchip0/pwmN/duty_cycle
echo 1 > /sys/class/pwm/pwmchip0/pwmN/enable

要修改引脚和开发板对应，然后其它地方不能占用这组引脚。

问题：如果同时连接了wifi和以太网，那么后连接的哪一个在ping时就会卡住

PING baidu.com (39.156.66.10) from 192.168.43.136 wlan0: 56(84) bytes of data.

1.单独连接wifi或者以太网时，都能ping通。
2.如果先接wifi 后连接以太网,当两个同时存在时。ping -I wlan0 baidu.com 能够ping通。但是 ping -I eth0 baidu.com 就不能ping通,卡在以下语句不动：

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。

captain

将XR829 补丁加入 bluez-5.50 里面进行编译，发现编译完成之后，发现没有 hciattach 命令的生成。

在 bluez-5.50/tools 路径下面，没有发现 hciattach 命令文件的生成。

这样设置并不能消除那个开机时候的警告吧！只是把 spi_board1 后面的设备地址去掉了。

使用longan_sdk 自带的文件系统，蓝牙可以正常识别，但是使用debian 文件系统就没有办法识别蓝牙。
参看XR829 蓝牙无法正确启动，说的是bluez 里面缺少 xradio下载功能，请问一下这个功能该怎么添加呢？
PS: debian 文件系统的 bluez 工具是直接通过 apt 安装的。

没有找到patch,但是根据这篇文章（如何使能D1-H/D1s uboot下的有线网卡？）进行修改，成功ping通了。
有一点疑惑，为什么修改kernel 的设备树会对uboot产生影响？

captain

时钟好像可以在sun8iw20p1-clk.dtsi 文件里面取消掉注释，就能使用了。

 clocks = <&clk_gmac0_25m>;

但是reset 这个脚，没有ccu ,该怎么配置呢？

 resets = <&ccu RST_BUS_EMAC0>;

问题：如何在uboot 下配置以太网时钟？
在uboot 下面配置以太网相关设备树时，发现只要加上这一句就会报错

  clocks = <&ccu CLK_BUS_EMAC0>, <&ccu CLK_EMAC0_25M>;

推测是没有ccu 相关内容。
uboot 下面，spi 配置也是注释了ccu相关内容的。

spi0: spi@4025000 {
	#address-cells = <1>;
	#size-cells = <0>;
	compatible = "allwinner,sun20i-spi";
	device_type = "spi0";
	reg = <0x0 0x04025000 0x0 0x300>;
	//interrupts-extended = <&plic0 31 IRQ_TYPE_LEVEL_HIGH>;
	//clocks = <&ccu CLK_PLL_PERIPH0>, <&ccu CLK_SPI0>, <&ccu CLK_BUS_SPI0>;
	//clock-names = "pll", "mod", "bus";
	//resets = <&ccu RST_BUS_SPI0>;
};

@whycan
我把dsp0 这个分区删除之后，发现不能正常启动了，可能还是使用了的。

captain

为了方便自动扩容，我把rootfs 分区和dsp0 进行了交换，然后修改了uboot里面的启动参数 mmc_root=/dev/mmcblk0p6 ，目前是可以使用的。
但是我还有两个疑问，大佬可以帮我解答一下吗？
1.没有在配置文件 env.cfg 里面找到环境变量 partitions，它是从哪里得来的呢？

partitions=boot-resource@mmcblk0p1:env@mmcblk0p2:env-redund@mmcblk0p3:boot@mmcblk0p4:dsp0@mmcblk0p5:@mmcblk0p6

2.交换 rootfs 分区和dsp0 会有什么不良影响吗？

        hdimage{
                partition-table-type = hybrid
                gpt-location = 1M
        }
        partition boot0 {
                in-partition-table = "no"
                image = "boot0_sdcard.fex"

请教一下，
1.t113-s3 没有DSP核，是不是可以去掉dsp0.fex 这个文件?
2.如果不去掉dsp0.fex 这个文件，有没有好的办法对根文件系统扩容？因为我发现，根文件系统后面还有dsp0 分区的话，就不好进行自动扩容了。

现在正确输出到串口了，参考 Linux 打印信息输出到lcd。
修改为以下启动参数，

console=tty0,ttyS3,115200

串口显示以下两句之后就不显示了，就卡到这里了。

[07.802]Starting kernel ...

[07.805][mmc]: MMC Device 2 not found
[07.808][mmc]: mmc 2 not find, so not exit

LCD屏幕也没有显示log,只显示了开机图片。

uboot设备树和内核设备树都匹配了lcd , 开机图片能够正确显示。

captain

破案了！！！
最后发现是rfkill没能正确导入的问题。
在设备树里面，rfkill的配置有问题，导致不能正确启用rfkill功能。（可在启动log里面查看rfkill启动情况。）
而wifi是依赖于rfkill的，所以wifi功能也不能正常启用。

之前在修改复用的时候，这个标号没对。现在已经修改正确了。

uart_debug_tx   = port:PB06<7><1><default><default>
uart_debug_rx   = port:PB07<7><1><default><default>```

@yuzukitsuru 在 T113-S3 增加 boot-resource.fex分区大小之后无法进行下载中说：

PhoenixSuit：因为喜欢用ADB，因为不喜欢插拔TF卡，所以D1直接用PhoenixSuit烧录TF(SDNAND)：https://bbs.aw-ol.com/topic/1002/share/1

使用这个方案是可以的，感谢！！

替换了一个bootlogo.bmp 图片之后，打包提示分区大小不够，屏幕截图 2022-07-21 104446.jpg
增加分区大小到提示大小之后，打包，进行下载，发现如下错误。

能不能贴一下具体的选项呀！全局搜索了一下uboot 下面的 .config ,没发现打开OPTEE的选项被选中。

问题：T113_longan_sdk uboot 启动的时候，串口没有打印。但是linux kernel启动的时候有打印输出。
上电之后会延迟一会，然后打印下面内容。

@memory 在芒果派麻雀到手试玩中说：

WIFI 驱动参考 https://linux-sunxi.org/Wifi
RTL8189FTV
Driver has its own repository:

git clone https://github.com/jwrdegoede/rtl8189ES_linux.git
cd rtl8189ES_linux.git
git checkout -B rtl8189fs origin/rtl8189fs
make -j4 ARCH=arm CROSS_COMPILE=arm-linux-gnu- KSRC=../linux

复制到 lichee/linux-5.4/drivers/net/wireless/ 目录。

根据这个方法，移植到T113_longin 。
报错：

linux-5.4/drivers/net/wireless/rtl8189fs/core/rtw_cmd.c:22:23: fatal error: drv_types.h: No such file or directory

查看了一下，它是有这个文件的。
