有漂移是正常，因为没有用电子罗盘修正航偏角，但是图上这么大的漂移其实是我的IMU融合搞得不好，我的师弟把我的融合改成四元素之后，漂移用这个上位机是看不出来的

电子产品保修问题相当严重等问题。
不幸的是，即使像我购买的焊机这样的德国产品也不好，它只是停止工作......
这种大件的，专业/偏门的产品保修都是非常麻烦，我相信每个国家都差不多。
现在中国国内的小家电产品基本不修了，
维修的报价还挺高，
修好的东西还不一定好用，
算算不如买新的了，
现国内京东买东西服务非常好，

山无棱 说：FEL 是芯片内置的 BROM 代码实现的, 是不是为了考虑兼容性强制进入 USB 1.0 模式？
全志官方的烧录软件都是先下载一个 u-boot 到芯片里面运行， 然后u-boot通过USB口与烧录软件通讯.
BROM进入FEL模式的枚举过程，通过bus hound可以抓到，里面的设备描述符显示的是USB 1.1协议。我所不理解的是为何实际使用的USB 1.0。
另外，你所说的全志官方烧录软件用到的这个u-boot有源码吗。感谢回复。
V3s 的官方 bsp camdroid 里面的 u-boot 貌似不开源, 反正我只能找到 boot0 和 u-boot 的二进制文件.
倒是 f1c100s 的 bsp 能找到 u-boot 源码,

do_mount做的事情很简单, 就是用支持的各个文件系统去试而已.
比较好奇, 为什么mount不成功为什么会跟那个选项有关 ? 百撕不得骑姐, 莫非读操作不成功?
是呀，都能正常启动到内核了， 我也是按你的方法， 没往cpu方面排查。initramfs 看似都正常，也没死机。
是读flash不成功， 读出来的是随机数，每次都不一样，不是所有的字节都能正常读出来。
后来了解， 内核启动后cpu，外设的频率重新设定。
也就是说启动 CONFIG_CPU_FREQ 改变了外设的频率， 可能导致spi nand读出了随机数?
而屏蔽了这个 CONFIG_CPU_FREQ, spi nand 就正常了？

根据晕哥提示， 我改成这样了:
int spl_mmc_load_image(struct spl_image_info *spl_image,
struct spl_boot_device *bootdev)
{
struct mmc *mmc = NULL;
u32 boot_mode;
int err = 0;
__maybe_unused int part;err = spl_mmc_find_device(&mmc, bootdev->boot_device);
if (err)
return err;int try_count = 0;
do
{
err = mmc_init(mmc);if (err)
{
#ifdef CONFIG_SPL_LIBCOMMON_SUPPORT
printf("spl: mmc init failed with error: %d\n", err);
#endif
try_count++;if(try_count > 10)
{
return err;
}
}
else
{
break;
}}while(1);
编译烧录中

我还把 MMC 的时钟速度降到 2M 了.

hjjft 说：
用过W5500，STM32F103C8T6驱动，还行。
W5500 快速 SPI 以太网控制器
特征：
支持高速SPI总线（SPI Mode 0,3）
支持硬件TCP/IP协议：TCP，UDP，ICMP，IGMP，IPv4，ARP，PPPoE
内嵌10/100Mbps以太网物理层
支持自动应答（全双/半双工模式）
多种指示灯信号输出（Full/Half duplex.Link, Speed）
支持8个独立的端口（sockets）同时连接
内部32K字节存储器作TX/RX缓存
支持休眠模式和网络唤醒
3.3V工作电压，I/O口可承受5V电压
极小巧的48 Pin LQFP无铅封装
但是现在这种网卡一点性价比都没有了，
一般新方案都会选用带ethernet mac的片子，
外面加一片 lan8720a,rtl8201f, 或者 ksz8041这种1块多钱人民币的片子即可,
更绝的是原来越多芯片带ethernet phy了，
直接接网卡座子就可以， 感觉好吊
