rootfs不建议用 jffs2，因为启动会扫描整个flash分区。

建议看下 @aodzip 的帖子，用 squashfs + overlayfs(jffs2) 这种方式，文件系统加载可以提升至2s内完成。

之前是kernel压缩方式是XZ（1.5s zImge 1.7m）
改成GZIP （0.53s zImge 2.2m）
改成LZO（0.45s zImage 2.5m）

uboot可以把一切不需要的功能剪裁掉，但是可能会有编译错误，一个一个解决，再试图提高spi clk，应该可以优化到0.5s。

问题1
uboot启动打log发现主要时间在D2--D3

static int env_sf_load(void)
{
	pr_err("<test>----D\n");
	int ret;
	char *buf = NULL;

	buf = (char *)memalign(ARCH_DMA_MINALIGN, CONFIG_ENV_SIZE);
	if (!buf) {
		set_default_env("!malloc() failed");
		return -EIO;
	}
	pr_err("<test>----D1\n");
	ret = setup_flash_device();
	if (ret)
		goto out;
	pr_err("<test>----D2\n");
	ret = spi_flash_read(env_flash,
		CONFIG_ENV_OFFSET, CONFIG_ENV_SIZE, buf);
	pr_err("<test>----D3\n");
	if (ret) {
		set_default_env("!spi_flash_read() failed");
		goto err_read;
	}
	pr_err("<test>----B\n");
	ret = env_import(buf, 1);
	if (ret)
		gd->env_valid = ENV_VALID;

err_read:
	spi_flash_free(env_flash);
	env_flash = NULL;
out:
	free(buf);

	return ret;
}

修改 Environment Size 即可

│  
  │ │                 Select the location of the environment (Environment is in SPI flash)  --->     │ │  
  │ │             (0x35000) Environment Offset                                                       │ │  
  │ │             (0x1000) Environment Size

修改前D2->D3花费2.7s
修改后D2->D3花费0.3s

哇酷小二说：

uboot可以把一切不需要的功能剪裁掉，但是可能会有编译错误，一个一个解决，再试图提高spi clk，应该可以优化到0.5s。

spi 108M
主频 816Mhz
ddr 480Mhz
uboot大小202kb

shaoxi2010 · 2023-09-04 09:23:06

这个太慢了，你确认过uboot的频率是不是100M哦，我没记错的话它默认用的24M时钟
从日志上看，你这uboot内核装载才4M/s的速度，远低于裸机的12M/s

资本家大善人 · 2023-09-04 23:55:41

uboot SPI默认1M速度设置100M 可加快0.3 0.4s

shaoxi2010 说：

这个太慢了，你确认过uboot的频率是不是100M哦，我没记错的话它默认用的24M时钟
从日志上看，你这uboot内核装载才4M/s的速度，远低于裸机的12M/s

fake100M: clk-100M ?

资本家大善人 · 2023-09-05 01:34:45

修改CONFIG_BOOTCOMMAND相关参数，修改uboot读取kernel的大小（2.2m）
开机优化到2.5s进终端

#define CONFIG_BOOTCOMMAND "sf probe 0 100000000; sf read 0x80C00000 0x100000 0x4000; \
sf read 0x80008000 0x110000 0x215000; bootz 0x80008000 - 0x80C00000"

留下的usb做虚拟串口终端
然后用Linux自带的iic-tools spi-tools 当debug工具

主要是好玩+练手
后面再加个屏幕玩玩

原来如此，优化的已经非常不错了，不过为啥不用RTT呢，这些工具也有，重点是秒启动

@xfdr0805
因为linux YYDS
之后可能会用f1c100玩点其他东西

把中间的信息打印去掉，只记录时间留到最后再打印，会有多大变化？

921600的波特率，就那些log，全部去掉省几十毫秒而已
