@anruliu 是不是跟旋转UI有强相关呢？如果是的话，显示驱动那边旋转的话是否能够规避这个问题呢？

hello @chengwei_peng ，不过我在 make kernel_menuconfig 当中，却有这个选项，不知道为啥机器上没有这个文件节点呢？

@rayzhang 在请教如何调节 Tina 的 cpufreq policy 中说：

hello @chengwei_peng

在我的编译环境里，
source ./build/envsetup.sh lunch 1 make kernel_menuconfig
之后就是这样的配置

90025087-3324-4037-a568-dd30f8dc818e-image.png

这里默认就是性能模式了吧？

另外我在设备上，没有找到相应的文件节点，不知道如何 double check 当前的CPU 是否处于性能模式呢？我的寻找方法如下（没有找到 scaling_governor 文件）：

@uuuuid 在换了四台电脑，终于让我悟出来NXP GUI Guider 为啥不能正常显示出设计界面的原因了中说：

装上 jre-8u341-windows-x64.exe 之后，一切就正常了。

成功搞定！

可以的，但是那样裁剪后就没多少地方放东西了，6mb的kernel，1mb的rootfs太极限了

请问不同驱动中的probe函数执行顺序是怎么样的？
Linux • Posted at • 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。

问题已解决，DNS解析顺序的问题，优先读了/etc/resolv.conf（软链接），注释或者删掉/tmp/resolv.conf的配置，系统就能自动读到/etc/hosts里的配置了

@jinxiangwzh 在关于TinaLinux4.9中的sys_config.fex的pwm配置中说：

@whycanservice 感谢回复这个看明白了

我另一组按键的配置为啥在这个文件中找不到无论是搜索gpiokey还是PD19都没有？
[gpiokey] compatible = "gpio-keys" autorepeat = 1 label = "capture_key" gpios = port:PD19<6><default><default><default> linux,input-type = <1> linux,code = 0x1ba

建议在board.dts中增加，linux4.9不需要再sys_config.fex中配置，而gpio-keys的配置，可以看看内核代码，这个是内核原生的，看看代码解析哪些字段信息，从而增加即可。

Replied at

@ivan_wan 确实，linux编译环境下打包脚本对应的是pack_img.sh。这个值应该是通过envsetup.sh里function pack()传进去的。source melis-env.sh 会调 envsetup.sh，然后调pack_img.sh。pack时可以加 -a [type] 指定存储介质，不然就是使用function pack()里默认的nor。

@dream 在【分析笔记】Linux I2C-Tools 使用踩坑笔记中说：

@daizebin sht41 的器件地址是 0x44，就决定了在自动模式下，是以写方式检测，所以可以识别到，但是 sgp41 的器件地址是 0x59，落在了以读方式检测的范围，所以无法识别到。具体看本文 scan_i2c_bus() 的源码截图就能看出来。

再补充一下，不是所有的 I2C 器件都必须要以写的方式才能检测出来，只有少部分，如 sht41\sgp41 这类器件比较特别，需要先写再读才有应答，正因为大部分 I2C 器件无论是读写都会有应答，所以才会因惯性思维，导致踩坑。

Any update on the source code? I have downloaded d1_freertos_20211105_4.rar.

I have done an independent version, pretty much came to the same results as here. All tick timer stuff works fine using CSR time and MMIO MTIMECMP. The comments about 'stability' bother me, mine runs for hours and hours doing simple stuff.

While working on my drivers for UART, TMR, SPI, etc. I always start with POLLING, then do INTERRUPT, then do DMA (where needed). All my polling stuff works fine. I can't get ANY of my interrupt stuff to work. My main problem is that I can't get ANY of the Peripherals to trigger the PLIC_IP registers to even initiate an External Interrupt to the CLINT. I've checked enables, priorities etc. Think I have them all set correctly.

I downloaded this version because it looked like it had some interrupt stuff in it. After searching through all the source code with a fine tooth comb I can only find the 'potential' for the interrupt, never a call from driver or application code to enable/use it.

Has anyone done any external interrupts (TMR or UART) in a FREERTOS Bare Metal environment?

Is there some secret mux or clock enable to get the TMR peripheral to connect to the PLIC to connect to MEI of CLINT? OpenSBI does enable the RISCV_CFG_BGR registers and I had hopes that would be the missing link, but it didn't fix it. MXSTATUS for Supervisor Delegation etc. isn't needed since FREERTOS runs in Machine mode. Any other suggestions?

Of course Linux/Tina must use interrupts but I've searched for hours in source code and can't find anything. Could be buried deep in the DTS.

@whycan 在 ( tina sdk ) package里gui的lvgl如何更新到8.2.0版本中说：

@jr_online
有两种方法，仅供参考：

① 比较 tina 里面的 lvgl8.0.1 和官方的lvgl8.0.1 看做了哪些修改，记录下来，lvgl8.2.0 做一样的修改。

②直接比较 tina lvgl8.0.1 和 lvgl8.2.0，针对性修改。

windows下比较软件beyond compare，linux下比较软件 diffuse/meld的，

可能都需要处理一点编译错误。

我们做了一下实验，把vio提高到2v，50M的时钟现在能识别wifi了，但是70M以上就还是不行。

然后我们空载的情况下测试了clk的幅度，T113 在120M时，明显幅度是不够的。作为对比，imx6ull 带载wifi 时，135M还能有2v 的幅度。

请问这个可能是什么问题？涉及寄存器设置？

（1）如果ramdisk_execute_command变量指定了要运行的程序，则启动它。 ramdisk_execute_command的取值分三种情况， 1）如果命令行参数指定了“rdinit=xxx”，则ramdisk_execute_command等于这个参数指定的程序 2）否则，如果/init程序存在，ramdisk_execute_command就等于“/init”。 3）否则，ramdisk__execute_command为空（2）如果execute_command变量指定了要运行的程序，启动它。如果命令行参数指定了"init=..."，则execute_command等于这个参数指定的程序，否则为空（3）如果ramdisk_execute_command和execute_command参数都没有指定，则依次执行”/sbin/init、/etc/init、/bin/init、/bin/sh“ 在tina系统中，我们可以通过去修改env.cfg文件”rdinit=xxx“或”init=xxx“参数来指定启动的第一个用户进程
