坛里各位大佬好！小弟前两年买了f1c200s的开发板，cherry-pi，无奈资料太杂乱，想试一下有什么可玩性，TF卡可正常启动，但测试nor 启动时，遇到问题
用如下命令写入16M spi flash，型号w25q128，按下reset按键，串口0 无输出：
./sunxi-fel -p spiflash-write 0x000000 .\suniv_f1c100s_w25q128_usb_lcd_ok_20190722\u-boot-sunxi-with-spl.bin
100% [================================================] 168 kB, 113.2 kB/s
看起来是flash写入正常。
如果通过：
./sunxi-fel -v uboot .\suniv_f1c100s_w25q128_usb_lcd_ok_20190722\u-boot-sunxi-with-spl.bin
Stack pointers: sp_irq=0x00002000, sp=0x00005E08
MMU is not enabled by BROM
=> Executing the SPL... done.

在串口是能看到启动过程的:

查询nor flash 信息：
./sunxi-fel spiflash-info

说明nor flash识别正常。
不知道为什么启动不了，困扰一天，请大佬指点一二。。。

谢谢晕哥分享资源。
问题搞清楚了。
mangopi cherrypi 用的uart1，licheepi用的uart0
怪不得烧录成功，串口没输出，板子电阻需要跳一下。
