Hi, |
| 2 |
|
| 3 |
(yes, I also have a FTDI USB<=>serial adapter...in this case I need to |
| 4 |
get my CH340 based work) |
| 5 |
|
| 6 |
this drives me crazy... |
| 7 |
|
| 8 |
My CH340G USB<=>serial adaptor is recognized as |
| 9 |
(lsusb) |
| 10 |
Bus 007 Device 011: ID 1a86:7523 QinHeng Electronics HL-340 USB-Serial adapter |
| 11 |
(dmesg) |
| 12 |

| 13 |

| 16 |
[52255.169580] ch341 7-4:1.0: ch341-uart converter detected |
| 17 |
[52255.179543] usb 7-4: ch341-uart converter now attached to ttyUSB3 |
| 18 |
|
| 19 |
|
| 20 |
But that's it. |
| 21 |
|
| 22 |
It does not seem to react on any kind of action I try to achieve with |
| 23 |
avrdude (I skipped the arduino IDE to get one variable off this |
| 24 |
eqyitation...). |
| 25 |
|
| 26 |
I instructed avrdude to "speak to the board" like this: |
| 27 |
avrdude -p ATmega2560 -c arduino -P /dev/ttyUSB3 -b 9600 |
| 28 |
|
| 29 |
...but the only reaction I get is ...timeouts... |
| 30 |
|
| 31 |
I have no clue what to do next. |
| 32 |
|
| 33 |
How can I devide the things which are working so far from those |
| 34 |
which are not working. |
| 35 |
|
| 36 |
The ATmega2560 board is working - I can flash it via buspirate (ICSP). |
| 37 |
I burned a bootloader with that...just to mention...not wanting to |
| 38 |
start an Arduino discussion on a Gentoo mailinglist...only to |
| 39 |
explain the context a little bit... |
| 40 |
|
| 41 |
What is the status of the ch340/ch341 driver? |
| 42 |
(I am running kernel 4.12.3 vanilla right off Linus desktop so to |
| 43 |
say...) |
| 44 |
|
| 45 |
Thanks a lot for any help in advance! |
| 46 |
Cheers |
