Hi everyone ,

I design a new PCB with reference of lichee Pi Schematic, but I removed SPI Flash as I don't need to boot from SPI Flash.
After soldering  board  I can't see signal on SDClock, But can see on SPI Flash Clock.

Unfortunately I also not reserve usb connector, as my idea was to flash sdcard pc side and boot the board.

Crystal is oscillating.

So with default boot form F1C100s it will not attempt to boot from SD ?
Any suggestion how to move forward ?

If no option, possibly I need to make new pcb with USB & SPI Flash.

嗨，大家好，

我参考lichee Pi Schematic设计了一个新的PCB，但由于不需要从SPI Flash引导，因此删除了SPI Flash。
焊完板后，我在SDClock上看不到信号，但在SPI闪存时钟上却看到了。

不幸的是，我也不保留USB连接器，因为我的想法是在sdcard pc侧进行闪存并启动开发板。

晶体振荡。

因此，使用默认引导形式F1C100s，它将不会尝试从SD引导吗？
任何建议如何前进？

如果没有选择，可能我需要使用USB和SPI Flash制作新的PCB

Thanks & Regards
