#1 全志 SOC » 请问下f1c100s使用xboot如何配置st7789呢? » 2021-09-20 18:51:39

回复: 0

本来打算使用linux的,可惜linux太难了(需要系统学习一下)
后来看见xboot不错,因为配置文件是用json的方式(老java程序员狂喜)
----------------
下线xboot
找到mach-f1c100s
在driver中没有发现st7789的驱动
但是在mach-h3/driver中有[fb-st7789v.c]便复制到mach-f1c100s/driver目录下
在[fb-st7789v.c]中发现有配置样例如下:

/*
 * LCD - Sitronix ST7789V Lcd Driver
 *
 * Example:
 *	"fb-st7789v@0": {
 *		"spi-bus": "spi-h3.1",
 *		"chip-select": 0,
 *		"type": 0,
 *		"mode": 0,
 *		"speed": 50000000,
 *		"reset-gpio": 9,
 *		"reset-gpio-config": 1,
 *		"cd-gpio": 16,
 *		"cd-gpio-config": 1,
 *		"width": 240,
 *		"height": 320,
 *		"physical-width": 30,
 *		"physical-height": 40,
 *		"backlight": null
 *	}
 */

我照着改成了下面这样

	"fb-st7789v@0": {
		"spi-bus": "spi-f1c100s.1",
		"chip-select": 0,
		"type": 0,
		"mode": 0,
		"speed": 50000000,
		"reset-gpio": 134,
		"reset-gpio-config": 1,
		"cd-gpio": 138,
		"cd-gpio-config": 1,
		"width": 240,
		"height": 320,
		"physical-width": 30,
		"physical-height": 40,
		"backlight": null
	},

下面是仿照spi0弄的spi1的接线
PC0(sclk64) - PA2(sclk2)
PC1(cs65) - PA0(cs0)
PC2(miso66) - PA3(miso3)
PC3(mosi67) - PA1(mosi1)

我把第二个spi也改了下

	"spi-f1c100s@0x01c06000": {
		"clock-name": "link-spi1",
		"reset": 21,
		"sclk-gpio": 2,
		"sclk-gpio-config": 4,
		"mosi-gpio": 1,
		"mosi-gpio-config": 4,
		"miso-gpio": 3,
		"miso-gpio-config": 4,
		"cs-gpio": 0,
		"cs-gpio-config": 4
	},

然后屏幕啥也没有
就不知道咋搞了

我实在内核5.7.1下成功的

我cs端连接到a0 上面写的是spi1:cs貌似还是不行,哎

我的内核版本是4.15.0-rc8-licheepi-nano+
我已经按照下面网址进行了操作
https://www.cnblogs.com/listenscience/p/13619930.html
这个地址所说的接线
SCLK ->    PA2
SDA    ->    PA1
CS   ->    GND
RESET  -> PE7
DC   -> PE10
但是我还剩余
BLK/VCC/GND没有接线,不接就啥都没有,所以我只能
VCC  -> VCC
BLK ->  VCC
GND  -> GND
但是可能是因为我是4.15的缘故
我修改了对应的fbtft-core函数编译会报错
不知道4.15是不是真的要修改

因为我spi0已经设置spi flash了
所以st7789v只能设置spi1
编译也没报错
启动没有fbtft的日志
dev/fb1设备也没有

请问下现在怎么处理呢?

另外想请教下在dts中下面的代码是否有存在的必要呢?

panel: panel {
                compatible = "lg,lb070wv8", "simple-panel";
                #address-cells = <1>;
                #size-cells = <0>;
                enable-gpios = <&pio 4 6 GPIO_ACTIVE_HIGH>;

                port@0 {
                        reg = <0>;
                        #address-cells = <1>;
                        #size-cells = <0>;

                        panel_input: endpoint@0 {
                                reg = <0>;
                                remote-endpoint = <&tcon0_out_lcd>;
                        };
                };
        };

还有这个

&tcon0 {
        pinctrl-names = "default";
        pinctrl-0 = <&lcd_rgb666_pins>;
        status = "okay";
};

&tcon0_out {
        tcon0_out_lcd: endpoint@0 {
                reg = <0>;
                remote-endpoint = <&panel_input>;
        };
};

先谢谢了:)

这是我弄成fbtft init_display 里面的代码

由于我看中了一款小屏幕
希望把他移植到我的nano上面来

其实目前我也只是自己刚编译好系统能进入linux而已
可是这款屏幕的芯片是gc9a01
fbtft里面没有提供对应的驱动
我也不知道如何编写
只是照着stm32代码写了init_display函数

我实在是不知道fbtft_display里面的set_var咋写了
准确的说,我其实啥都不知道,请问下我现在应该怎么用最简单的方式驱动这个屏幕呢?

mtd是【drivers/mtd/spi-nor/spi-nor.c】这个文件吗
我里面注释掉了
/*{ "w25q128", INFO(0xef4018, 0, 64 * 1024, 256, 0) },*/
增加了
{ "xt25f128b", INFO(0x0b4018, 0, 64 * 1024, 256, 0) },

@哇酷小二
jffs2 那个 mtd是啥
我是按照
https://whycan.com/t_3138.html
这个地址的第五点来搞的
是用
BuildMyImage.sh这个命令烧写进去的,其他的我就不知道咋搞了

#23 Re: 全志 SOC » 请问下这里是哪里错了呢? » 2021-08-07 20:35:19

我已经重新编译了但是还是不行

#28 Re: 全志 SOC » fel进不去了,请问怎么处理呢?多谢 » 2021-08-01 20:49:59

@哇酷小二
这个方法是不是烧写到tf卡,然后在tf卡上启动吗?
主要是我不太想在tf卡上启动
我想在spi上烧录

可以进入命令行吗?

可以进入uboot的命令行,但是我只知道一个help命令哈哈哈
不好意思,有点菜

f1c100s拿来我只需要连接flash的第1和第4引脚就可以烧录
但是我自己烧录进去一个自己编译好的uboot后,就无法通过上面这种方式进入到fel了
看论坛可以通过TF卡的方式进入
我按教程使用下面这个命令进行烧写

 dd if=fel-sdboot.sunxi of=/dev/sdb bs=1024 seek=8 

但是只要插上TF启动,连uboot都进不去
使用

 sunxi-fel -l

命令也找不到对应的设备
请问下各位大佬应该怎么处理呢?
不甚感激

但是uboot的驱动我不太会搞
也没有找到好多资料

可以直接移植到linux吗?

微凉VeiLiang 说:

没有看懂。连接串口不打印是怎么供电的。连接usb能重新打印芯片信息不是等于这个供电才是真的供上电么

就是普通的5v/rx/tx/gnd供电,不过我又重新烧写了一遍就可以了,哈哈哈哈,不好意思,没弄过这个

我的spi  flash芯片是
xt25f128b
但是我下载了官方的uboot后啥也没改[故意啥也没改,想看看报错信息,也啥都不会改],编译成功得到u-boot-sunxi-with-spl.bin
然后使用
sunxi-fel -p spiflash-write 0 ./u-boot/u-boot-sunxi-with-spl.bin
进行烧录
烧录也是成功的
但是链接串口啥也不打印,而且发烫
连接usb能重新打印芯片信息[芯片没坏]
请问下怎么排查呢?谢谢
