【官方發(fā)布】CH9344 USB轉(zhuǎn)四串口芯片Linux驅(qū)動

你好，我在kernel4.4上運行這個ch9344.ko時（1.16版本，makefile沒有修改），提示：

insmod: can't insert '/system/lib/modules/ch934x.ko': invalid module format


同樣的編譯器編譯其他的驅(qū)動，就沒問題，急，求幫助


謝謝

如果修改makefile

把KERNELDIR := /lib/modules/$(shell uname -r)/build


改成：KERNELDIR ?=$(KERNEL_DIR)


則編譯報錯：

您好，建議先明確下編譯其他驅(qū)動所引用的Kernel Src是否和CH9344引用的相同。常規(guī)情況若一樣不會提示格式不兼容，也可以使用file或module相關(guān)命令檢查下ko文件兼容性。另，不排除你的系統(tǒng)存在多個版本的kernel-headers。

這個是另一個驅(qū)動的makefile


ifneq ($(KERNELRELEASE), )

obj-m := common.o?

else

KERNELDIR ?=$(KERNEL_DIR)

PWD? ? ? ?:= $(shell pwd)




default:

$(MAKE) -C $(KERNEL_DIR) M=$(PWD) modules

endif


clean:

rm -rf *.d *.o *~ core .depend .*.cmd *.ko *.mod.c .tmp_versions modules.order Module.symvers


depend .depend dep:

$(CC) $(CFLAGS) -M *.c > .depend


ifeq (.depend,$(wildcard .depend))

include .depend

endif

感覺還是ch934x的makefile導(dǎo)致的問題，但是我如果改了makefile又編譯出錯，如上38樓

TECH39 發(fā)表于: 2021-01-20 09:38:24

您好，對于默認(rèn)makefile編譯出錯問題，應(yīng)該是編譯驅(qū)動kernel src沒有對應(yīng)到默認(rèn)makefile指定的路徑。改用你第二種方式理論上可行，出錯是因為你系統(tǒng)默認(rèn)makefile規(guī)則要求，強制將warning當(dāng)成錯誤?？蓢L試：

1、修改kernel src的makefile，取消將警告當(dāng)作錯誤的問題；

2、修改ch934x.c其中的warning的未使用函數(shù)進(jìn)行注釋，重新編譯；

denny123 發(fā)表于: 2021-01-20 19:48:05

你好，編譯出錯的問題，我已經(jīng)改好了，把未使用的函數(shù)注釋了就好，但是加載驅(qū)動的時候，沒有提示錯誤，/dev/目錄下也沒有生成對應(yīng)的設(shè)備節(jié)點，這個是為什么？


以下是加載驅(qū)動的log：

?insmod /system/lib/modules/ch934x.ko?

usbcore: registered new interface driver usb_wch

ch934x: USB driver for USB to serial chip ch9344.

ch934x: V1.16 On 2020.12.05


TECH39 發(fā)表于: 2021-01-29 15:27:14

如上問題，是由于系統(tǒng)未能正常識別到CH9344設(shè)備導(dǎo)致。關(guān)于驅(qū)動加載成功但節(jié)點未產(chǎn)生時，建議先通過“l(fā)susb”或"dmesg"命令查看usb設(shè)備的識別和工作情況。

您好，上述的問題現(xiàn)在都解決了，現(xiàn)在想把9344串口信號轉(zhuǎn)成485信號，這個是否支持呢，我在使用gpio時，發(fā)現(xiàn)不能控制，一直是低電平


tty device test ok.

press s to set modem, z to clear modem, g to get modem, b to send break, w to write, r to read, G to test gpio, q for quit.

G

press e to enable gpio, d to disable gpio, press o to set gpio output, i on input, d to disable gpio, h to output high, l on low, g to get gpio, q for quit.

e

press e to enable gpio, d to disable gpio, press o to set gpio output, i on input, d to disable gpio, h to output high, l on low, g to get gpio, q for quit.

o

press e to enable gpio, d to disable gpio, press o to set gpio output, i on input, d to disable gpio, h to output high, l on low, g to get gpio, q for quit.

h

press e to enable gpio, d to disable gpio, press o to set gpio output, i on input, d to disable gpio, h to output high, l on low, g to get gpio, q for quit.


以上操作無效果

比較著急，請問有了解gpio使用方式的嗎

TECH39 發(fā)表于: 2021-04-16 10:51:59
27#

您好，如上驅(qū)動和應(yīng)用是支持芯片GPIO操作的，且CH9344芯片的RS485控制信號串口發(fā)送時自動控制無需通過軟件開啟。若測試遇到無法正常進(jìn)行，先通過系統(tǒng)命令lsusb或sysfs查看當(dāng)前ch9344的usb revision版本號（v36.00及以上可支持），有疑問可按照下方聯(lián)系方式與我溝通。

你好，謝謝回復(fù)

我這邊用的是嵌入式linux，lsusb只能看到這些信息，


[root@rk3328:/]# lsusb

Bus 004 Device 002: ID 1a86:e018

Bus 001 Device 001: ID 1d6b:0002

Bus 002 Device 001: ID 1d6b:0002

Bus 003 Device 001: ID 1d6b:0001

Bus 004 Device 001: ID 1d6b:0002

Bus 005 Device 001: ID 1d6b:0003


我需要如何確定9344的內(nèi)部版本呢

usb設(shè)備插入后輸入dmesg信息 ，查看usb枚舉的詳細(xì)信息即可。

你好，我掃了一遍沒找到相關(guān)信息哦，9344已經(jīng)加載進(jìn)來了
