H616是好东西，但我发现大家还是更喜欢F1C200S/V3S这些板子

这是因为H616画PCB的要求更高

BusHound的问题是软件驱动要读走数据才能看到，其他的都挺好。

因为工作的关系平时用一点Linux,装的双系统。公司的管理系统只管到了Windows,所以最近半年一直主力是Linux。本人做一点点软件，主力开发是做硬件，在Windows下的，这不想以后想都搞在Linux下做开发。
Linux的Ui看个人，平时都是用ubuntu感觉还不错了，就是显卡驱动没有Windows下做的好。
其实如果使用LinuxMint的话，基本感觉不出与Windows的UI差别，体验还是很好的，预装的软件也很全，就连ubuntu的显卡驱动问题都不存在。个人感觉太像Windows了，反而有点排斥。
KiCAD吧，前段时间也想学的，系统上也装了，不过在行业内好多人以cadence为标杆，感觉用这个才算是高端的硬件设计。
其实我cadence 和KiCAD都不怎么熟，最熟的是大家都熟的那个软件。

在网上下载了cadence SPB 17.2 linux，尝试着ubuntu安装了以后，不知道怎么设置环境变量，破解了没有完全做好，现在不能通过终端输入allegro &来启动软件，提示是没有这个命令。

用什么算法，什么机制，想好了可以选不同的芯片，加密芯片可以选U盾里的那些，价格没有2块那么便宜，量少基本3块多点。包括了几乎所有国密安全算法。
所以你最先要做的是先把机制和算法选好。

在这里再记录一下，临时解决液晶颜色问题，第3种修改RGB到BGR的方法；

由于使用的是buildroot-tiny200，他的液晶驱动还是在uboot里通过参数传到内核的（见下面的代码，chosen）

       chosen {
                #address-cells = <1>;
                #size-cells = <1>;
                ranges;
                //for NAND or Nor
                bootargs = "console=tty0 console=ttyS0,115200 rootwait init=/preinit root=/dev/mtdblock2 rootfstype=squashfs overlayfsdev=/dev/mtdblock3";
                //for sd-card
//              bootargs = "console=ttyS0,115200 earlyprintk rootwait init=/preinit root=/dev/mmcblk0p3";
                simplefb_lcd: framebuffer-lcd0 {
                        compatible = "allwinner,simple-framebuffer",
                                     "simple-framebuffer";
                        allwinner,pipeline = "de_be0-lcd0";
                        clocks = <&ccu CLK_BUS_DE_BE>, <&ccu CLK_DE_BE>,
                                 <&ccu CLK_DRAM_DE_BE>, <&ccu CLK_BUS_LCD>,
                                 <&ccu CLK_TCON>;
                        status = "disabled";
                };

我现在还不懂设备树的原理，试过的前两种方法也都没有解决问题，所以就想通过uboot的液晶驱动来改，最终经过分析找到了文件./output/build/uboot-2020.07/arch/arm/include/asm/arch-sunxi/lcdc.h，把文件的第79行，修改成下面这样。临时解决了液晶的颜色问题。

#define SUNXI_LCDC_TCON0_CTRL_ENABLE            ((1 << 31) | (1 << 23))
//#define SUNXI_LCDC_TCON0_CTRL_ENABLE          (1 << 31)

pldjn_V3S · 全志 SOC

在这个文件里board/widora/mangopi/r3/devicetree/linux/devicetree.dts 好像是没有使用内核的设备树里驱动LCD。
查了下chosen是从uboot传来的参数。

       chosen {
                #address-cells = <1>;
                #size-cells = <1>;
                ranges;
                //for NAND or Nor
                bootargs = "console=tty0 console=ttyS0,115200 rootwait init=/preinit root=/dev/mtdblock2 rootfstype=squashfs overlayfsdev=/dev/mtdblock3";
                //for sd-card
//              bootargs = "console=ttyS0,115200 earlyprintk rootwait init=/preinit root=/dev/mmcblk0p3";
                simplefb_lcd: framebuffer-lcd0 {
                        compatible = "allwinner,simple-framebuffer",
                                     "simple-framebuffer";
                        allwinner,pipeline = "de_be0-lcd0";
                        clocks = <&ccu CLK_BUS_DE_BE>, <&ccu CLK_DE_BE>,
                                 <&ccu CLK_DRAM_DE_BE>, <&ccu CLK_BUS_LCD>,

我记得这个SDK里面的uboot没有支持lcd，如果确实要支持lcd得试一试荔枝派仓库里面的sdk了。

regmap_update_bits(tcon->regs, SUN4I_TCON0_CTL_REG,BIT(23),BIT(23));//SWAP R、B引脚
在这前后把寄存器值都打印出来看看。

linux/drivers/gpu/drm/sun4i/sun4i_tcon.c这个文件不知道是没有调用到其中的函数，还是我加的调试信息不对，我增加了条printk，然后sh rebuild-kernel.sh ,没有在串口上看到信息。

printk("sun4i_tcon.c printk test\n");

uboot的LCD那个先跳过去了，现在是想把RGB改成GBR，试了2种方法都没有成功。

pldjn_V3S · 全志 SOC

@哇酷小二

再问一下怎么修改buildroot，把RGB改成BGR；尝试了2个方法都没成功。
1，参考https://whycan.com/t_6781.html,在文件 linux/drivers/gpu/drm/sun4i/sun4i_tcon.c添加 "regmap_update_bits(tcon->regs, SUN4I_TCON0_CTL_REG,BIT(23),BIT(23));//SWAP R、B引脚" 删除.stamp_built重新编译，没有效果；

2，参考https://gitee.com/IOTTS/f1c100s_buildroot，在文件./board/allwinner/suniv-f1c100s/devicetree/linux/suniv-f1c100s.dtsi中添加 rgb-channel-swap = <1>; /* 设置为1为BGR格式 */ ，重新编译，没有效果；

用busybox修改寄存器的值可以切换BGR，正确显示图片；

busybox devmem 0x01c0c040
busybox devmem 0x01c0c040 w 0x80800100

pldjn_V3S · 全志 SOC

针对buildroot-tiny200,这个应该怎么改？
我在./output/build/linux-5.4.99/drivers/gpu/drm/sun4i/sun4i_tcon.c 文件中修改了，重编译没有起作用。不知道为什么。
用busybox devmem 0x01c0c040 指令去修改寄存器是可以切换的，哪位朋友能提供下具体修改方法。

整理总结一下；

代码默认使用的是Uart1做为log输出，若要修改成Uart0输出需要修改以下几个部分：

1，board/widora/mangopi/r3/uboot.defconfig

CONFIG_CONS_INDEX=2

2，修改 board\widora\mangopi\r3\devicetree\uboot\suniv-f1c100s-generic.dts的下面这块，改成serial0 = &uart0;就有log输出了；

	aliases {
		serial0 = &uart0;
		spi0 = &spi0;
	};

	chosen {
		stdout-path = "serial0:115200n8";
	};

3, Linux 需要修改 ./board/widora/mangopi/r3/devicetree/linux/devicetree.dts ，增加下面这块，才会有log输出。

&uart0 {
        pinctrl-names = "default";
        pinctrl-0 = <&uart0_pe_pins>;
        status = "okay";
};

代码修改成 16M nor spi flash ，需要修改以下几点：
1，需要修改：./board/widora/mangopi/r3/devicetree/linux/devicetree.dts

//for NAND or Nor
  bootargs = "console=ttyS0,115200 rootwait init=/preinit root=/dev/mtdblock2 rootfstype=squashfs 
  overlayfsdev=/dev/mtdblock3";
//for sd-card
//bootargs = "console=ttyS0,115200 earlyprintk rootwait init=/preinit root=/dev/mmcblk0p3";

2，Linux的设备树board\widora\mangopi\r3\devicetree\linux\devicetree.dts里 spi-nor@0 部分要把 status = "disabled" 注掉，spi-nand@0 部分要把status = "disabled"加上。

&spi0 {
	status = "okay";

	spi-nor@0 {
		#address-cells = <1>;
		#size-cells = <1>;
		compatible = "winbond,w25q128", "jedec,spi-nor";
		reg = <0>;
		spi-max-frequency = <50000000>;
	//	status = "disabled";

		partitions {
			compatible = "fixed-partitions";
			#address-cells = <1>;
			#size-cells = <1>;

			partition@0 {
				label = "u-boot";
				reg = <0x000000 0x70000>;
				read-only;
			};

			partition@1 {
				label = "kernel";

				read-only;
			};

			partition@3 {
				label = "overlay";
				reg = <0xd00000 0x300000>;
			};
		};
	};

	spi-nand@0 {
		#address-cells = <1>;
		#size-cells = <1>;
		compatible = "spi-nand";
		reg = <0>;
		spi-max-frequency = <50000000>;
                status = "disabled";
		partitions {
			compatible = "fixed-partitions";
			#address-cells = <1>;
			#size-cells = <1>;

哇酷小二说：

改完 uboot.env 要重新编译uboot :
rm output/build/uboot-2020.07/ -rf && make

这个不是从uboot.env文件获取的参数，是直接写死到Linux的设备树文件里的。在这个文件里./board/widora/mangopi/r3/devicetree/linux/devicetree.dts，这里为什么nor是root=/dev/mtdblock2，而sd卡是root=/dev/mmcblk0p3。

  //for NAND or Nor
  bootargs = "console=ttyS0,115200 rootwait init=/preinit root=/dev/mtdblock2 rootfstype=squashfs overlayfsdev=/dev/mtdblock3";
  //for sd-card
  //bootargs = "console=ttyS0,115200 earlyprintk rootwait init=/preinit root=/dev/mmcblk0p3";

对，改设备树。

改完设备树, 有一个快速编译的方法:
rm output/build/linux-5.4.66/.stamp_built -rf && make
这样就能重新生成linux 设备树二进制文件了.

uboot亦然.

试了，修改 board\widora\mangopi\r3\devicetree\uboot\suniv-f1c100s-generic.dts的下面这块，改成serial0 = &uart0;就有了；Linux的还是没有，到了Starting kernel ...␍␊就停了。

	aliases {
		serial0 = &uart0;
		spi0 = &spi0;
	};

	chosen {
		stdout-path = "serial0:115200n8";
	};

Linux 需要修改 ./board/widora/mangopi/r3/devicetree/linux/devicetree.dts ，增加下面这块，才会有log输出。

&uart0 {
        pinctrl-names = "default";
        pinctrl-0 = <&uart0_pe_pins>;
        status = "okay";
};

改这个：

然后删除uboot的编译目录：
rm output/build/uboot-2020.07/ -rf
重新make即可。

这样改过以后，确实有了log输出，uboot的前一半有了，后一半没出来。后一半是不是需要修改设备树；一会再去修改了试试先。

@哇酷小二

修改F1C200S的uboot，console接口，都要改哪些地方，我按照坛里的帖子修改了几个地，还是没有输出到uart0上。第3项我没找到声明的地方，不知道是什么原因；

1， board\widora\mangopi\r3\devicetree\uboot\suniv-f1c100s-generic.dts

	aliases {
		serial0 = &uart0;
		spi0 = &spi0;
	};

	chosen {
		stdout-path = "serial0:115200n8";
	};

&uart0 {
        pinctrl-names = "default";
        pinctrl-0 = <&uart0_pins_a>;
        status = "okay";
};

&uart1 {
        pinctrl-names = "default";
        pinctrl-0 = <&uart1_pins_a>;
        status = "okay";
};

2,board\allwinner\suniv-f1c100s\devicetree\uboot\suniv-f1c100s.dtsi

                        uart0_pins_a: uart-pins-pe {
                                pins = "PE0", "PE1";
                                function = "uart0";
                        };

                        uart1_pins_a: uart1-pins-pa {
                                pins = "PA2", "PA3";
                                function = "uart1";
                        };

                uart0: serial@1c25000 {
                        compatible = "snps,dw-apb-uart";
                        reg = <0x01c25000 0x400>;

                        status = "disabled";
                };

                uart1: serial@1c25400 {
                        compatible = "snps,dw-apb-uart";
                        reg = <0x01c25400 0x400>;

                        status = "disabled";
                };

3, 这块未找到，在文件/output/build/uboot-2020.07/include/configs/sunxi-common.h中没有找到CONFIG_CONS_INDEX这块的定义。

#define CONFIG_CONS_INDEX              1       /* UART0 */

4，uboot的.config中添加

CONFIG_BOOTARGS="console=ttyS0,115200 rootwait init=/preinit root=/dev/mtdblock2 rootfstype=squashfs overlayfsdev=/dev/mtdblock3"

我在mangopi 的官网下载了一个sysimage-nor的镜像，烧到我的板上，也是没有跑起来系统，串口没有Log,液晶有显示uboot的log，进入了Linux系统,不知道为什么液晶没有显示。
不过可以确认的是，他的log不是从uart0输出的。
所以如果再搞两天还是搞不定这个的话，只能去试试mangopi R3的那版buildroot

改正一下：
看到了，原来mangopi R1的串口是uart0，R3的就默认是uart1了。

我准备使用buildroot-tiny200 (F1C100/200s) 开发包近期更新内容 * 已支持DVP摄像头 *，支持SPI NAND 给我的F1C200S小板编译Linux固件，遇到一些问题，特开贴请教。
1，我编译的固件烧录到芯片，串口没有信息输出，不知道是不是与DTS文件中的 serial0 = &uart1 有关，为什么这里要把uart1给serial0；

/dts-v1/;
#include "suniv-f1c100s.dtsi"

#include <dt-bindings/gpio/gpio.h>

/ {
        model = "Allwinner F1C100s Generic Device";
        compatible = "allwinner,suniv-f1c100s",
                     "allwinner,suniv";
        aliases {
                serial0 = &uart1;
                spi0 = &spi0;
        };

        chosen {
                stdout-path = "serial0:115200n8";
        };
};

2, 在uboot.env中为什么这些值都那么大？
sf_size=0x1000000
sf_splash_offset=0x80000
sf_kernel_offset=0x100000
sf_kernel_length=0x500000

splash_addr=0x80000000
splash_length=0x80000

kernel_addr_r=0x81000000

bootm_size=0x1800000
按照下面这行，那bootcomv好像不适合SPI Flash ,也不知道自己的理解对不对。

nor_boot=echo "Booting from SPI-NOR..."; sf probe; sf read ${kernel_addr_r} ${sf_kernel_offset} ${sf_kernel_length};

为了方便我把/board/allwinner/generic/uboot.env文件的内容贴出来；

mmc_bootpart=2
mmc_rootpart=3

nand_size=0x8000000

问一下晕哥：

board/widora/mangopi/r3/devicetree/uboot/suniv-f1c100s-generic.dts里的这段serial0 = &uart1;会影响到串口0的输出吗？

/dts-v1/;
#include "suniv-f1c100s.dtsi"

#include <dt-bindings/gpio/gpio.h>

/ {
	model = "Allwinner F1C100s Generic Device";
	compatible = "allwinner,suniv-f1c100s",
		     "allwinner,suniv";

	aliases {
		serial0 = &uart1;
		spi0 = &spi0;
	};

		stdout-path = "serial0:115200n8";
	};

我今天试着读了一下写到芯片内的u-boot进行了对比，发现写进去与读出的是一样的，但这个bin文件并没有正常的串口信息输出，看不到uboot是否运行。
不知道有哪个设置会影响uboot的运行，按说设置了ARM及内核926,uboot就应该会在芯片上跑起来。
make widora_mangopi_r3_defconfig
应该会把基本配置写到.config文件里面去吧。
我看了一下mangopi r3的原理，console的串口应该也是uart0，实在不知道是哪里出了问题，还有哪里会影响uboot。

今天发现电流稍大一点的那块板子，原来是焊接问题，不是CPU短路，而是LCD的座子那块焊短路了。修复后焊接正常了。接下来还是要研究系统软件。

问一下，这个软件怎么擦除SpiFlash?

@aodzip 的SDK我使用16M的W25Q128，一直不能正确的跑起Uboot，自己新手，这个问题解决不了，所以翻回头来搞这个能跑起来的代码，先把板子上能测的部分测试一下。后面再研究aodzip 的SDK。
现在是板上的LCD颜色没改对，分辨率发现搞对了。现在开机是这个状态。颜色先不管了，后面再弄，现在去找个TF试试。

更正，分辨率好像还是不对，后面还有8行没有显示出来。

今天遇到２个问题:
1 ,修改液晶RGB到BGR没有成功，按https://whycan.com/viewtopic.php?id=6781的方法添加下面的代码，修改linux的 linux/drivers/gpu/drm/sun4i/sun4i_tcon.c 文件，重新编译打包后，小企鹅的脚还是蓝的，没有变成黄色。

regmap_update_bits(tcon->regs, SUN4I_TCON0_CTL_REG,BIT(23),BIT(23));//SWAP R、B引脚

２,修改uboot的液晶分辨率，配置 LCD panel timing details为分辨率480x272，结果只有开始的小企鹅那块好像是对的，后面Linux的信息都不对。

x:480,y:272,depth:18,pclk_khz:10000,le:42,ri:8,up:11,lo:4,hs:1,vs:1,sync:3,vmode:0

我现在用不起来，主要是烧写到16M的SPI Flash，串口没有输出信息，不知道SD卡或NAND Flash那些能不能工作，我现在还没有试到那一步。

pldjn_V3S · 全志 SOC

buildroot-tiny200 的SDK还没有搞定，编译完后烧写到Spiflash uboot没有串口输出。
回头又去重新git了nano-lcd800480分支，编译了一个1M大的u-boot，打包以后，明显还是不正常，Linux没有正常shell,但是由于换了uboot，现在LCD可以显示了，需要换一下颜色改成GBR。
对Linux不太懂，学起来也是散的，自己是搞到哪不会了，就搜一下。还没有找到好的学习方法。

今天对F1c200S进行了烧录，PCB上是焊接的W25Q128，写进去的是下面这个sysimage-nor.img文件，结果芯片上电串口没有输出任何字符，说明u-boot没有启动，这是为什么。是我烧写的文件不对吗？我自己编译的那个固件是可以启动linux进入shell的。不知道如何解决。我看自己编译的固件与sysimage-nor.img是同样大小的。

更新一下，
烧进sysimage-nor.img以后，串口没有输出，但是F1C200S 已经不是跑在FEL了，应该还是跑了uboot了。

我把c-stack.c的这部分代码注掉，又会出新的错误。所以感觉是版本问题。

#elif HAVE_LIBSIGSEGV && SIGSTKSZ < 16384
/* libsigsegv 2.6 through 2.8 have a bug where some architectures use
   more than the Linux default of an 8k alternate stack when deciding
   if a fault was caused by stack overflow.  */
# undef SIGSTKSZ
# define SIGSTKSZ 16384

新的错误是一堆的_STAT_VER相关

libfakeroot.c: In function ‘chown’:
libfakeroot.c:99:40: error: ‘_STAT_VER’ undeclared (first use in this function)

@哇酷小二
感谢晕哥，我去学习一下这个

pldjn_V3S · 全志 SOC

问一下，我的u-boot没有液晶显示，在哪里可以添加，我现在用的是nano-2018.01这个分支。没有找到关于480x272液晶的相关配置。

手焊的两片PCB，其中一片电流偏大了大概30mA，系统启动后PCB电流大概是90mA，F1C200S芯片微热；另一片正常的电流是60mA大概，看来主芯片手焊还是挺考验技术的。

找到原因了，是u-boot 的suniv.h文件里修改过的内容，学习过程中给注掉了。
还原以后，就可以正常启动Linux了。
我是按照这个帖子一步步学习的https://whycan.com/viewtopic.php?id=3138 ，就是下面这段代码，我给注掉了。

#define CONFIG_BOOTCOMMAND   "sf probe 0 50000000; "                           \
                             "sf read 0x80C00000 0x100000 0x4000; "  \
                             "sf read 0x80008000 0x110000 0x400000; " \
                             "bootz 0x80008000 - 0x80C00000"

正常的启动了Linux。

1，个人资料里面没有自己的发贴列表，不知道在哪里可以看到。
2，好久没有实际的进展了，最近收到了一批快递，终于。。终于把这个板子焊齐了。
3，最近在学习编译uboot、内核、buildroot，现在都可以正确编译了，但是还没有烧录测试，不知道是不是能够运行在芯片里。
4，使用sunxi-fel工具把uboot烧进了SPIFlash里，串口工具里面看到了log信息。

因为这是我刚开始学习Linux的开发，进展比较慢；
这是CuteCom软件的uboot的输出信息，现在还不知道uboot是不是正确的，自己学着编译的版本，不是网上下载的。

PWM没有使用，R19没焊接或者LCD-PWM直接输出的高电平

那你用示波器看看，你的输出电压是不是振荡了，boost电路在设计的时候，Layout的要求要比Buck要高一点。

看错了，是有直接切换RB的位。
这样布线的时候应该可以方便点，省得PCB这块都要过孔绕线。
我对了一下，Lichee nano 和公版的F1C200S的原理图，在这块是反的。不知道当时设计的时候的原因是什么。如果按公版的原理图，这块的线都直连了，不需要绕线。

我想的是可以兼容当前市面上的一些派，可以使用40Pin的插针，搞一些板级的接口啥的。在系统要求不高的时候可以使用V3S，要求高了就换其他派。

这种结构在iphon10里面有，类似BGA焊接；我觉得在开发板上用这个结构可能并不是最优选择，iPhone在重摔以后也很容易因为掉点，造成信号不断连。感觉开发板应该是个很皮实的东西。
