nandflash

由于公用数据线

Cubemx 启用Nandflash2，无法设置参数

自己 bsp_nand，重新设置参数初始化控制 IO，需要自己初始化

// IO : PB13 R/B, PG9 CE, PD4 PD5 PD11 PD12 static void HAL_NAND_MspInit_Control_IO(NAND_HandleTypeDef *hnand)

Malloc

内存分配 FTL 可能用到

需要设置 LD

.sdram (NOLOAD) : 
{ 
. = ALIGN(4); 
_sdram_begin = .; 
*(.sdram) 
*(.sdram*) 
. = ALIGN(4); 
_sdram_end = .; 
} >SDRAM 
.sdrammap (NOLOAD) : 
{ 
. = ALIGN(4); 
__sdrammap_begin = .; 
*(.sdrammap) 
*(.sdrammap*) 
. = ALIGN(4); 
__sdrammap_end = .; 
} >SDRAMMAP

FTL

直接整合到 nand Flash？直接分配系统内存，就2-3k大小

DMA2D启用

ARGB8888

LTDC

只能选 RGB565 屏rgb888 16.7 兼容 rgb565 touch GT911

Cubemx 改不了hbp vbp 的值，需重新初始化去修改

每层的格式为 ARGB8888

****Cubemx 的配置如下，只有RGB565的配置，没有RGB888需要的IO配置 ****

基本参考正点原子，原子的hsw 这些的定义有些问题

GT911 驱动

可以参考下野火的，有软件IIC 有硬件IIC。但是野火的软件IIC 有点问题硬件iic 可以设置一个值，让前端去轮询，轮询到执行 Scan 获得坐标可以参考
https://blog.csdn.net/weixin_38411122/article/details/129241223 https://github.com/oy2n/stm32cube-gt911-dma

touch 可以识别到触点了

字体中文图片

Display_char 有点问题

nandFlash NorFlash USB虚拟U盘

spiFlash 分区，配置写入分区自己定义在FATFS目录下的文件，没有被编译需要改写 user 文件

FATFS 修改

FATFS/target 目录, 添加 nand_diskio.c nand_diskio.h
FATFS/APP/fatfs.h 引入 nand_diskio.h
FATFS.c MX_FATFS_Init 修改引入驱动引入flash Driver的定义

uint8_t retUSER;    /* Return value for USER */
char USERPath[4];   /* USER logical drive path */
FATFS USERFatFS;    /* File system object for USER logical drive */
FIL USERFile;       /* File object for USER */

头文件 extern 出去，供外部引用

在 MX_FATFS_Init 初始化

void MX_FATFS_Init(void)
{
  /*## FatFS: Link the SD driver ###########################*/
  retSD = FATFS_LinkDriver(&SD_Driver, SDPath);
  /*## FatFS: Link the USER driver ###########################*/
  retUSER = FATFS_LinkDriver(&USER_Driver, USERPath);
}

FATFS_LinkDriver 来自 Middlewares/Third_Party/FatFs/ff_gen_drv.c
SDPATH   UserPath 含有lun 信息, 即盘符 0:  1:

ffcong.h 磁盘数量定义 #define _VOLUMES 1

Middlewares/Third_Party/FatFs/

添加文件

extern uint8_t retNAND; /* Return value for USER */
extern char NANDPath[4]; /* USER logical drive path */
extern FATFS NANDFatFS; /* File system object for USER logical drive */
extern FIL NANDFile; /* File object for USER */
