Re: xboot stops before xboot prompt.

你确认你的串口线输入没有问题?感觉f1c100s没有收到uart 数据

Re: xboot stops before xboot prompt.

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..

Re: xboot stops before xboot prompt.

你用的是 USB 转 TTL 的数据线吗?用什么驱动芯片 PL2303? CP2014?或者其他的

既然用Linux出现乱码, 感觉这种情况与数据线关系比较大.

xboot does not proceed, when inputing by keyboard.

Re: xboot stops before xboot prompt.

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.

Re: xboot stops before xboot prompt.

1. 你有没有两片 nano.板子,如果有可以换一片试一试
2. 测试cp2104自发自收是否正常,测试方法是短路 cp2104的RX与TX,然后用串口软件发数据,看能否收到自己发出去的数据。
3. 可以下载本bbs的其他linux镜像测试

Re: xboot stops before xboot prompt.

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

用 master 分支吗?是有可能,因为xboot最近在测试 K210 双核 risc-v 方案,最新的代码可能会造成其他soc出问题,建议用老一点的版本。

这个分支能用, 但是有点老了,最好用master 早一些时候的版本。
