43
+此电路用于用户连接系统调试中断使用，其功能为将TTL串口转换为USB接口，使得用户可以在电脑中连接该串口进行调试。
44
+
45
+需要注意的是，由于F1C200S的UART0接口(PE0/PE1引脚)被触摸的I2C接口占用，所以本开发板将CH340的串口连接到了F1C200S的UART1(PA2/PA3引脚)上，后续编译U-Boot和内核时我们需要相应的修改代码。

50
+
51
+如上图所示，该部分除了串口转USB外，还兼顾的系统的供电，用户通过Type-C线缆连接该调试口后，将同时为开发板供电。板上的5.1K电阻用于双头Type-C线缆识别从机，为其提供供电，如果R12,R13不焊接会导致使用双头Type-C线时板子没有供电。D2为TVS瞬态抑制二极管用于保护PCB板上原件，防止静电击穿原件。

+U-Boot Overview
93
+
94
+U-Boot (Universal Boot Loader) is an open-source bootloader widely used in embedded device startup processes. As a powerful and versatile boot tool, it supports multiple processor architectures and embedded platforms.
95
+
96
+During system startup, U-Boot is responsible for initializing various hardware components, including but not limited to the CPU, memory controller, interrupt controller, and timer. It also loads the operating system kernel and root filesystem. U-Boot provides an interactive command-line interface for configuration, debugging, and maintenance.
97
+
98
+Typically, U-Boot serves as the first-stage bootloader, with its main task being to load and execute the operating system from different storage media (such as flash, SD card, or network). This makes U-Boot a key role in the embedded device boot process.
99
+
100
+Features and Functions of U-Boot:
101
+
102
+- Cross-platform compatibility: Supports a wide range of processor architectures, including ARM, x86, PowerPC, and MIPS, and can run on various embedded platforms. It adapts flexibly to different hardware configurations and system requirements.
103
+- Highly customizable: Offers rich configuration options and extensibility, allowing developers to tailor and optimize U-Boot for specific embedded system needs.
104
+- Multiple boot methods: Supports serial boot, network boot (via TFTP or NFS), SD card boot, and flash boot.
105
+- Interactive command-line interface: Users can perform device initialization, memory tests, filesystem operations, network configuration, and more.
106
+- Diverse filesystem support: Supports FAT, EXT2/3/4, UBIFS, and other filesystems, enabling loading and booting of different root filesystems.
107
+- Powerful debugging and diagnostic tools: Provides features for system debugging and troubleshooting, such as memory tests, device registration info display, and log recording.
108
+
109
+F1C200S Chip Boot Process:
110
+
111
+1. When power is applied, the internal BROM (non-erasable chip ROM) of the F1C100S starts.
112
+2. It first checks if an SD card is inserted in slot 0. If present, it reads data at an 8K offset to determine if it is valid boot data. If valid, BROM boot ends; otherwise, it proceeds to the next step.
113
+3. It checks for the presence of SPI0 NOR FLASH (e.g., W25QXXX or MX25LXXX) and verifies if valid boot data exists. If found, BROM boot ends; otherwise, it continues.
114
+4. It then checks for SPI0 NAND FLASH and validates if it contains valid boot data. If found, BROM boot ends; otherwise, it moves to the next step.
115
+5. If no bootable media is found in the above steps, the system switches to USB FEL mode, allowing USB programming.
116
+6. After BROM boot ends, the SPL (Second Program Loader) is loaded. SPL loads U-Boot into RAM, and U-Boot is then fully loaded.
117
+
118
+U-Boot Startup Sequence:
119
+
120
+- Upon starting, U-Boot loads the device tree configured at compile time, loads the corresponding drivers, locates the stored kernel or configuration files, and then starts the kernel according to user-defined boot commands and Linux kernel parameters.
121
+- After the kernel starts, U-Boot's role is complete.
122
+- Note: U-Boot also requires a device tree, mainly to help load memory and basic peripherals. This device tree does not need to be complex—usually, only memory and UART nodes are required.

60
+该部分用于驱动RGB屏幕背光，标准40Pin RGB屏幕基本采用串联背光，由于本身开发板供电只有5V，所以我们需要使用背光驱动芯片升压到合适的电压，来驱动屏幕背光。同时，背光驱动芯片采用恒流控制，可以避免电流过大导致背光LED烧毁，该部分原理图如下所示：
61
+
62

63
+
64
+其中：
65
+
66
+C19 C20为滤波电容，C19电容的耐压需要特别考虑，一般的RGB屏背光电压基本在18V以上(白光LED压降3V*6串)，过低的电容耐压会导致电容损坏。
67
+
68
+BL_CTR为芯片背光控制引脚，此处直接接入了上拉，再开发时可以将BL_CTR引脚接入F1C200S的PWM引脚上，这样可以灵活控制屏幕亮度，同时，有恒流驱动的存在，控制亮度时，背光也不存在明显的频闪。
69
+
70
+L1 为升压电路的电感，按照要求一般取10uh或22uh即可，不需要使用公式详细计算，但是需要注意电流不能超过电感额定电流。
71
+
72
+R5为芯片的反馈电阻，用于调节输出的电流，计算公式可参考下方：

+
76
+图2.13反馈电阻计算公式
77
+

79
+
80

+## SPI NOR Flash
43

44
+Nor Flash为F1C200S芯片提供了第二种启动方式。
45
+
46
+上电后，F1C200S首先从内部BROM (芯片内置，无法擦除)启动；
47
+
48
+首先检查 SD0 有没有插卡, 如果有插卡就读卡 8k偏移数据，是否是合法的启动数据, 如果是BROM 引导结束, 否则进入下一步；
49
+
50
+第二步：检测SPI0 NOR FLASH是否存在, 是否有合法的启动数据, 如果是BROM 引导结束, 否则进入下一步；
51
+
52
+第三步：检测SPI0 NAND FLASH 是否存在, 是否有合法的启动数据, 如果是BROM 引导结束, 否则进入下一步；
53
+
54
+最后，因为找不到任何可以引导的介质，系统会进入usb fel模式，此时可以使用USB烧录。
55
+
56
+此处SPI Nor Flash可以同时兼容Nand Flash，不过目前裸机资料基本上都是以SPI Nor Flash为基础，所以此处焊接了W25Q128JVEIQ 128Mbit(16Mbyte)SPI Nor Flash。
57
+
58
+该部分原理图如下所示：

+
60

61
+
62
+图2.9 W25Q128JVEIQ原理图
63
+
64
+其中：
65
+
66
+R4为上拉电阻(F1C200S内部也存在上拉电阻，可以不焊)，防止未供电时芯片错误写入数据;
67
+
68
+C16为滤波电容;
69
+
70
+SW2为FEL模式开关，将SPI_MISO短路到地后，F1C200S将无法检测到SPI Nor Flash，从而进入USB Fel模式，此时可以松开按键，烧录内容至SPI Nor Flash。
71
+
72
+/WP为SPI Nor Flash保护引脚，低电平有效，有效时无法写入数据
73
+
74
+/HOLDor/RESET为SPI Nor Flash保持或者复位输入引脚。
75
+
76
+此处由于SPI Nor Flash内部默认设置，/HOLDor/RESET和/WP引脚即使不拉高，芯片也会照样运作。

213
+如上图所示，相关线路说明如下所示：
214
+
215
+CLK: SDMMC时钟，每个时钟周期传输一个命令或数据位。频率可在0至25MHz之间变化。SD卡总线管理器可以自由产生0至25MHz的频率，没有任何限制。
216
+
217
+CMD: 命令传输线，命令通过该CMD线串行传输。
218
+
219
+D0～D3: 数据通过这些数据线传输。
220
+
221
+按照SDMMC规范，SDMMC线路还需要增加10K上拉电阻，如果没有可以会影响数据传输，本原理图中R7-R11即上拉电阻。同时，为了保证电源质量，增加了C22滤波电容。
222
+
223
+SHELL引脚为SDMMC连接器固定引脚，此处接地处理，CD引脚用于探测SD卡是否插入，这一块悬空未使用。
