CH341 is not set

[Omirax 0]

Hello!

/proc/config.gz

# CONFIG_USB_SERIAL_CH341 is not set

Why and HOW?

It's very important for me!

Kernel 4.4.194 and I can't install headers (not found) for make driver...

Please help!

Hi Omirax,

We would add that config in future. And here is the source code: https://github.com/TinkerBoard2/kernel/tree/tinker_board_2-debian_10-2.0.0

and kernel header: https://github.com/TinkerBoard2/kernel/releases/download/tinker_board_2-debian_10-2.0.0/Tinker_Board_2-Debian-Buster-v2.0.0-20210413.zip (in GitHub release page)

Thanks.

Hello Frank3_Wu!

Can I use this img for Asus Tinker R? 

I flashed the SD card, inserted it into the slot, but my Tinker R won't start ...

I have not yet decided to flash EMMC

One more:

linaro@linaro-alip:~/work/ch340/CH341SER$ sudo modprobe usbserial
modprobe: ERROR: ../libkmod/libkmod.c:586 kmod_search_moddep() could not open moddep file '/lib/modules/4.4.194/modules.dep.bin'
modprobe: FATAL: Module usbserial not found in directory /lib/modules/4.4.194

How fixed this?

No, is different kernel source. For Tinker Edge R please use this: https://github.com/TinkerEdgeR/debian-kernel

Or you means Tinker R/BR? for Tinker R/BR or Tinker S/BR, please reference Tinker Board or Tinker Board S. And kernel source here: https://github.com/TinkerBoard/debian_kernel

Hello!

So sorry.
We use Asus Tinker Edge R, so I am posting in the forum section for Tinker Edge R.
And I was surprised when you wrote that we can use the image from Tinker 2S.
Ok. Now we have only one problem for start tests our project.

hello @sri, 

did you do step 4). which is to create defconfig?

[sri 0]

Hello @tooz,

The problem is it should be rk3399pro-tinker_edge_r.img instead of tinker_edge_r

and also there are errors compiling scripts/dtc/dtc-lexer.lex.c_shipped  because of multiple definitions of yyalloc on main branch

[tooz 52]

hello @sri, 

in \debian-kernel\scripts\dtc\dtc-lexer.lex.c, line 634

please change

YYLTYPE yylloc;

to

extern YYLTYPE yylloc;
