用v3x做了个小板，分享一下

qianniao29 · 2021-10-18 00:12:52

之前从晕哥那里买了两片v3x，做了个小板，打算搞个掌机玩玩。打样回来焊接了下，编了个uboot烧录sd卡，断断续续调试了几周，终于可以正常启动了。分享下原理图，后续再继续调试。由于本人的水平比较有限，也是业余搞搞，所以做得也比较业余，分享出来仅供大家讨论。

漂亮，芯片多少钱买的啊？
也想打个板学习学习。

简单编了个kernel，版本Linux 5.13.9，可以正常进入Linux。
使用configs下的suxi_deconfig
dts与uboot差不多，都是基于pinecube改的

将uboot，kernel和文件系统烧录到sd卡，参照论坛上的方法：
1) 删除TF卡所有分区
2) 将uboot写入到sd卡8k偏移处(必须8K偏移, brom龟腚的)。
sudo dd if=u-boot-sunxi-with-spl.bin of=/dev/sdX bs=1024 seek=8
3) 建立第一个分区,大小32M(可以随意填写), 格式FAT16, 把zImage, sun8i-v3s-licheepi-zero-dock.dtb拷贝到这个分区
4) 建立第二个分区，用尽剩余空间,格式ext4, 把buildroot产生的rootfs.tar解压到该分区根目录
tar xvf output/images/rootfs.tar -C /挂载的tf卡第二个分区目录

下一步准备调试下网口和屏幕，困了，睡觉了。。。

启动log如下：

试了这个，可以用，SD卡启动需要在driver中打开sd host驱动

qianniao29 · 2021-10-21 21:12:34

网口调试：
打开driver中的sun8i emac,编译报错
In function ‘parse_phy_pins’,
inlined from ‘sun8i_emac_eth_of_to_plat’ at drivers/net/sun8i_emac.c:972:3:

346 | compiletime_assert(condition, msg, compiletime_assert, __COUNTER)

修改sun8i_emac.c

static int parse_phy_pins(struct udevice *dev)
{
    ......

    if (IS_ENABLED(CONFIG_MACH_SUNXI_H3_H5))
        iomux = SUN8I_IOMUX_H3;
    else if (IS_ENABLED(CONFIG_MACH_SUN8I_R40))
        iomux = SUN8I_IOMUX_R40;

    //新增
    else if (IS_ENABLED(CONFIG_MACH_SUN8I_V3S))
        iomux = SUN8I_IOMUX;
    ......
}

修改sun8i-v3x-game.dts文件

&emac {
    compatible = "allwinner,sun8i-h3-emac"; //compatible = "allwinner,sun8i-v3s-emac";为compatible = "allwinner,sun8i-h3-emac";
    pinctrl-0 = <&emac_rgmii_pins>;
    phy-handle = <&int_mii_phy>;
    phy-mode = "mii";
    allwinner,leds-active-high; //led高电平点亮
    status = "okay";
};

2. 定义pin
emac_rgmii_pins: emac0@0 {
        allwinner,pins = "PD0", "PD1", "PD2", "PD3",
                       "PD4", "PD5", "PD7",
                       "PD8", "PD9", "PD10";
        function = "emac";
        drive-strength = <40>;

修改drivers/clk/sunxi/clk_v3s.c文件，增减CLK_BUS_EMAC，CLK_BUS_EPHY，RST_BUS_EMAC，RST_BUS_EPHY的定义

static struct ccu_clk_gate v3s_gates[] = {
	[CLK_BUS_MMC0]		= GATE(0x060, BIT(8)),
	[CLK_BUS_MMC1]		= GATE(0x060, BIT(9)),

	[CLK_BUS_UART1]		= GATE(0x06c, BIT(17)),
	[CLK_BUS_UART2]		= GATE(0x06c, BIT(18)),

	[CLK_BUS_EPHY]		= GATE(0x070, BIT(0)),

	[CLK_SPI0]		= GATE(0x0a0, BIT(31)),

	[CLK_USB_PHY0]          = GATE(0x0cc, BIT(8)),
};

static struct ccu_reset v3s_resets[] = {
	[RST_USB_PHY0]		= RESET(0x0cc, BIT(0)),

	[RST_BUS_MMC0]		= RESET(0x2c0, BIT(8)),

	[RST_BUS_UART1]		= RESET(0x2d8, BIT(17)),
	[RST_BUS_UART2]		= RESET(0x2d8, BIT(18)),
};

重新编译烧录，启动后设置板卡的mac和ip即可ping通电脑

楼主请问环境变量如何存储至SD卡上呢？
目前uboot貌似不支持savenv命令。

你好搂住,用axp这个电源方案 ,又没有遇到过系统插着串口线再上电,电源没有输出的问题?

记得有个文档上说，这个芯片的串口没有做放倒灌，所以断电后芯片可能没有复位，需要将串口连线断开，芯片才会复位。不知道你这个问题跟倒灌有没有关系。

好久没来更新了，板子基本功能调试的差不多了，已初具雏形。屏幕调试花了挺长时间，调试记录见：https://whycan.com/t_8686.html
其他按键，esp8089，alsa音频参考论坛里的帖子调了调驱动。

请问一下参考了什么资料呢

主要参考了论坛上v3s的相关资料，编译uboot，kernel，驱动之类的。

请问还有空板吗？

有的，gerber文件已经放到GitHub了，或者你可以自己去打板。
