A33板子修改U-BOOT调试串口失败，大佬们帮忙分析一下

weiyongwill · 2020-12-06 22:27:00

买了个3D打印机，里面有块A33的主板，原来是Android4.4的系统，不过没有引出调试口，但是有个LCD接口，还有测试点，看到有两个端口可以复用为UART1，PD10/PD11
复用UART1
于是开始了艰难的修改之路，用的是主线U-boot 2021.01
直接用了Sinlinx_SinA33_defconfig的配置
sun8i-a33-sinlinx-sina33.dts文件修改以下内容

aliases {
		serial0 = &uart0;
		serial1 = &uart1;
	};

	chosen {
		stdout-path = "serial1:115200n8";
	};
&tcon0 {
	pinctrl-names = "default";
	pinctrl-0 = <&lcd_rgb666_pins>;
	status = "disabled";
};
&uart1 {
	pinctrl-names = "default";
	pinctrl-0 = <&uart1_pins_b>;
	status = "okay";
};

sun8i-a33.dtsi文件修改以下内容

&pio {
	compatible = "allwinner,sun8i-a33-pinctrl";
	interrupts = <GIC_SPI 15 IRQ_TYPE_LEVEL_HIGH>,
		     <GIC_SPI 17 IRQ_TYPE_LEVEL_HIGH>;

	uart0_pins_b: uart0@1 {
		pins = "PB0", "PB1";
		function = "uart0";
	};
	uart1_pins_b: uart1@1 {
		pins = "PD10", "PD11";
		function = "uart1";
	};

};

u-boot/arch/arm/include/asm/arch-sunxi/gpio.h增加下面内容

#define SUN8I_A33_GPD_UART1	4

u-boot/arch/arm/march-sunxi/board.c增加下面内容

#elif CONFIG_CONS_INDEX == 2 && defined(CONFIG_MACH_SUN8I)
	sunxi_gpio_set_cfgpin(SUNXI_GPD(10), SUN8I_A33_GPD_UART1);
	sunxi_gpio_set_cfgpin(SUNXI_GPD(11), SUN8I_A33_GPD_UART1);
	sunxi_gpio_set_pull(SUNXI_GPD(11), SUNXI_GPIO_PULL_UP);

u-boot/include/configs/sunxi-common.h增加并修改如下

#elif CONFIG_CONS_INDEX == 2 && defined(CONFIG_MACH_SUN8I)
#define OF_STDOUT_PATH		"/soc@01c00000/serial@01c28400:115200"

#define CONFIG_EXTRA_ENV_SETTINGS \
	CONSOLE_ENV_SETTINGS \
	MEM_LAYOUT_ENV_SETTINGS \
	DFU_ALT_INFO_RAM \
	"fdtfile=" FDTFILE "\0" \
	"console=ttyS1,115200\0" \
	SUNXI_MTDIDS_DEFAULT \
	SUNXI_MTDPARTS_DEFAULT \
	"uuid_gpt_esp=" UUID_GPT_ESP "\0" \
	"uuid_gpt_system=" UUID_GPT_SYSTEM "\0" \
	"partitions=" PARTS_DEFAULT "\0" \
	BOOTCMD_SUNXI_COMPAT \
	BOOTENV

并且把 menuconfig> Device Drivers > Serial drivers>(2) UART used for console
改成2，这样autoconf.h里面的#define CONFIG_CONS_INDEX 2

所有的改完编译运行

sudo sunxi-fel -v uboot u-boot-sunxi-with-spl.bin
Stack pointers: sp_irq=0x00002000, sp=0x00005E08
MMU is not enabled by BROM
=> Executing the SPL... done.
Writing image "U-Boot 2021.01-rc3-00023-gee1e04", 500661 bytes @ 0x4A000000.
Starting U-Boot (0x4A000000).

U-boot的menuconfig里面总共关了CONFIG_VIDEO_SUNXI CONFIG_VIDEO CONFIG_VIDEO_DT_SIMPLEFB 三个选项

可是串口毫无波澜，原本运行Android时那个LCD管脚还会疯狂输出乱码。
大佬们帮忙看看还需要修改哪些内容，才能用这个串口1输出调试信息。

有没有可能PD10/11 的 UART1复用被LCD初始化覆盖了?

多谢大佬指点，哪里可以设置关闭LCD，是在uboot设置里面，还是需要改代码？

	status = "disabled";
};

又关了CONFIG_VIDEO_DT_SIMPLEFB，现在没有报错了，编译成功，晚上试试串口输出

现在才知道怎么能快速在Menuconfig里面定位搜索，只需要按 / 就可以输入搜索的内容了，总共关了CONFIG_VIDEO_SUNXI CONFIG_VIDEO CONFIG_VIDEO_DT_SIMPLEFB 三个选项，用搜索功能可以很快能定位到

依然是没有数据，可以确认U-boot是启动了，USB设备变成了RNDIS/Ethernet Gadget 了。

还没能找到问题吗？

weiyongwill · 2020-12-10 10:11:35

还没呢，等大佬指导。另外改变思路，从LCD打印调试信息了

shaoyie · 2020-12-17 11:02:41

如果是想用LCD那边的测试点，fex中
[uart1]
uart_used = 1
uart_type = 4
uart_tx = port:PG06<2><1><default><default>
uart_rx = port:PG07<2><1><default><default>
是不是应该改为
uart_tx = port:PD10<3><1><default><default>
uart_rx = port:PD11<3><1><default><default>
类似地，设备树中的
&uart1 {
pinctrl-names = "default";
pinctrl-0 = <&uart1_pins_b>;
status = "okay";
};
uart1_pins_b是不是也应该改为uart1_pins_a
