what branch do you recommend?

The branch f1c100s-kk131 works well. Thanks.

I found that xboot smp_processor_id() returns non zero. so all tasks stop.

hotpeperoncino · 全志 SOC

i checked serial line. I use CP2014.
xboot does not proceed, when inputing by keyboard.
Serial line has no noise after reconnecting to usb. so i think there is no problem with serial line.

Thank you. I notice serial lines has trouble.

hotpeperoncino · 全志 SOC

I checked my serial. It is ok to communicate. When linux is installed, linux can boot and i can input characters to linux shell from PC keyboard though terminal software.
But sometime it may contain noise data.
I don't know how to avoid such noise data.
when linux is installed, after several times i plug and unplug USB cable repeatedly, the noise data looks flushed,
then it looks works well and boot successfully.
but xboot cannot boot to shell..

hotpeperoncino · 全志 SOC

I made xboot.bin.
And boot it like the following.
but i cannot get xboot prompt..
is it correct?

Thank you for your reply. I understand.

This image shows that the spi clk should be connected to GND in order to enter FEL mode.
With connecting spi clk with GND, I inserted USB cable to USB connecter of PC side.
Then the nano board falls in FEL mode.
Thank you for your support.

以下描述说明为了清除spl-flash内容，连接flash 1和4。
licheenano板上哪个引脚是“flash 1 pin”和"flash 4 pin"？

1.短接flash 1、4脚(当flash中无可引导代码时无需此步骤)
2.连接USB
3.松开短接的引脚
4.输入下列指令

Are there bootable image containing linux and buildroot for lichee nano which boots from spl-flash ?
My build now stops when mounting rootfs.

对，你观察仔细, licheepi nano f1c100s PCB板的引脚丝印(PA0..3)确实反了
https://whycan.cn/t_1650.html

谢谢。此图像似乎连接spi clk和gnd。如果我连接像这个图像的电线，电路板会进入FEL模式吗？
可以的, 按下按钮就可以进入 FEL 模式，然后可以用 sunxi-fel 烧录.
对了，你是日本国人吗？

thank you, again.

我正在使用licheepi nano（f1c 100s）。我在号码上犯了一个错误。

A0 (SPI CS), A2 (SPI CK)

我认为它是A0或A2，哪一个是它？

短接spi flash cs引脚到gnd，然后加电，就可以强制进入fel状态

谢谢

SPI flash cs == D4 pin ?

我应该将D4引脚连接到GND？

hotpeperoncino · 全志 SOC

I found the following description in document. so I'll try it.

进入fel模式
Zero有一个usb下载模式称为fel模式，进入fel模式有下面几种方式：

TF卡和spi flash 同时没有可启动镜像;
也就是说你不插卡，且焊接的是新的或者没有有效镜像的spi flash，那就上电自动进入fel下载模式
TF卡中有进入fel模式的特殊固件 fel-sdboot.sunxi
如果你的spiflash已经有了启动镜像，那么需要在TF卡中烧入一个sunxi提供的启动工具（ dd if=fel-sdboot.sunxi of=/dev/mmcblk0 bs=1024 seek=8 ），那么插入该TF卡启动会进入fel模式；
上电时SPI_MISO拉低到地
该引脚为boot引脚，上电时出于低电平即会进入fel下载模式。

我写了uboot和linux到lichee pi的spi flash。为了能够从spi flash启动。

lichee pi启动uboot并启动了linux。

但是，之后，PC不再将lichee pi识别为USB设备。
因此，我无法使用sunxi-fel编写新的uboot和linux。

如何使用sunxi-fel编写新的uboot和linux？

如何删除在licheepi nano的spi flash中编写的uboot和linux并将新的uboot和linux写入spi flash?
