这块板子，这张卡烧我做的固件正常?

换了一张卡后打印的信息又不一样了

贴片式T卡  来顶一顶。支持一下

我现在重新clone一个uboot 直接编译玩后下载后  就是同一样的结果

再不行就加上这个: https://whycan.cn/t_2050.html#p14059

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);

看上面的 log 降低 MMC 的频率， spl & u-boot 都跑起来了.

再把 u-boot 里面的 DRAM 和 CPU 频率都降下来。

可以直接修改 .config 文件

DRAM 166M
CPU    800M

CONFIG_DRAM_CLK=166
CONFIG_SYS_CLK_FREQ=800000000

试一试这样.

这有点尴尬，烧我的固件不会酱紫?

下载你的没有问题

好的 下午试试
我刚才烧写刚下载的uboot 打印的信息是下面  这个新的uboot 我就修改了DRAM和CU时钟

下载新uboot 烧写进去了uboot是起来 就是一直这样了

步骤没有错的 git clone https://github.com/Lichee-Pi/u-boot.git -b v3s-spi-experimental

至今没有找到答案 虽然可以跑起来了
我昨天是从新下载了一个uboot带spi  然后在sun8i.h里面设置了TF启动  后面就直接烧写TF卡中  就起来了 ，
我不知道是不是uboot直接cp过来原因的
