原本使用的是uart0
[uart_para]
uart_debug_port = 0
uart_debug_tx = port:PB22<2><1><default><default>
uart_debug_rx = port:PB23<2><1><default><default>
想要改为别的串口，比如uart2，但是改了之后烧录不了
[uart_para]
uart_debug_port = 2
uart_debug_tx = port:PI18<3><1><default><default>
uart_debug_rx = port:PI19<3><1><default><default>
试过改成其他的也不行，只有将下面的内容注释是可以烧录的，烧录后进文件系统后会在uart0输出日志信息
[uart_para]
;uart_debug_port = 0
;uart_debug_tx = port:PB22<2><1><default><default>
;uart_debug_rx = port:PB23<2><1><default><default>
请问有没有什么办法解决？

@duanzhh 抱歉我到现在也没有解决这个问题

MasterLu

@whycanservice 谢谢回复。
我已经在clk驱动中将module_platform_driver(clk_driver);
改成了
static int __init clk_init(void)
{
return platform_driver_register(&clk_driver);
}
arch_initcall(clk_init);//arch_initcall 等级为3
我通过kernel log 看，clk_driver 执行probe的时间确实有提前，但是有的使用module_init的驱动还是会在clk_driver之前执行probe。这让我感觉很疑惑。
我想过将驱动编译为module,但是clk涉及到很多功能，像是gpio，lcd，audio等，如果将上述的驱动都使用module，那就涉及到这些部分的驱动可能都需要编译成module，这样做是否会很奇怪。

MasterLu

最近遇到一个问题，内核启动的时候clk probe函数没有执行，导致很多功能在获取clk的时候报错，我尝试过修改驱动init的等级比如将module_init改为arch_initcall,这样操作，有时候确实有效，但是并不是都有效。
所以我想请问一下大佬，probe的顺序是否能够修改？谢谢

@masterlu 目前发现单独编译出来的8723bu.ko文件安装上去能够正常使用ap，整体编译内核输出在output/lib/modules/3.10.65下的8723bu.ko文件无法使用ap，会报No WPA/RSN IE from STA的错误。

MasterLu

RTL8723bu模块STA模式功能正常，AP模式不设置密码可以连接，设置密码后无法连接，报错信息为No WPA/RSN IE from STA。内核版本为3.10.65
在客户平台有有一条类似的问题《Tina-xr829无法连接加密ap》https://open.allwinnertech.com/#/faq/0/show，仿照这条问题进行修改，依然没有效果。
希望有大佬能给一下解决思路。

下面是启动hostapd时的log

@masterlu 多次收发123的结果是这样的，似乎每一次收发的时间都会比之前的要长一些。。。。

接收：

使用A40i的spi转串口，spi2 ，串口芯片是wk2412。
目前的问题：使用转出来的串口进行收发数据（比如发送123）大多数情况下会有1s左右的延迟才能接收到，比较好的情况是几乎感受不到延迟，最差的情况是接收到123时需要等待6s左右。
不知道有没有大佬遇到过这种情况，希望能提供一些解决办法或者思路，谢谢。
