[gentoo-user] We have had known workarounds for python:3 and icu in uclibc-ng for a few months but they havent yet been implemented

2017-07-25 Thread Iván 
First im not sure if this belongs here or in -dev, posting here just in
case.

Second, i must say im not trying to be agressive. I aprecciate the
developers work, specially maintaining a side project.

Uclibc-ng, for some reason, cant read relative paths for LD_LIBRARY_PATH

I barely know about ebuilds and dont even know how to submit a patch. But
in python and icu bugtrackers you can find workarounds to both problems.

https://bugs.gentoo.org/show_bug.cgi?id=591586

https://bugs.gentoo.org/show_bug.cgi?id=608312

For python one, you would need to remove PYTHON_SITEDIR from local vars
(line 268) and add in the next line

local -x LD_LIBRARY_PATH=${LD_LIBRARY_PATH+${LD_LIBRARY_PATH}:}$PWD

As for icu, we can declare the variable in the ebuild, this ought to be
enough.

export
LD_LIBRARY_PATH=${WORKDIR}/icu/source-*/lib:${WORKDIR}/icu/source-*/stubdata

Both these options wrapped under a if elibc=uclibc-ng obviously.

If the device creates a /dev node there is probably no issue with the
driver. The default Arduino speed is now 57,600, are you sure 9,600 is
right? Before that it was 38,400. Use the ICSP interface to flash a
program that prints things via serial and see if you can receive them.
If your serial connection is unreliable you will get garbled
characters.

Avrdude should eventually time out with a message, what is that message?

I have been experiencing similar problems that you have described with
various Arduino and Arduino-derived boards and so far have not been
able to explain it. Most of the time they work perfectly but some do
not and the bootloader seems to refuse to work.

[gentoo-user] Struggling with CH340 serial<=>USB converter (Arduino related)

2017-07-25 Thread tuxic 
Hi,

(yes, I also have a FTDI USB<=>serial adapter...in this case I need to
get my CH340 based work)

this drives me crazy...

My CH340G USB<=>serial adaptor is recognized as
(lsusb)
Bus 007 Device 011: ID 1a86:7523 QinHeng Electronics HL-340 USB-Serial adapter
(dmesg)
[52255.016438] usb 7-4: new full-speed USB device number 11 using ohci-pci
[52255.167432] usb 7-4: New USB device found, idVendor=1a86, idProduct=7523
[52255.167439] usb 7-4: New USB device strings: Mfr=0, Product=2, SerialNumber=0
[52255.167443] usb 7-4: Product: USB2.0-Serial
[52255.169580] ch341 7-4:1.0: ch341-uart converter detected
[52255.179543] usb 7-4: ch341-uart converter now attached to ttyUSB3


But that's it.

It does not seem to react on any kind of action I try to achieve with
avrdude (I skipped the arduino IDE to get one variable off this
eqyitation...).

I instructed avrdude to "speak to the board" like this:
avrdude -p ATmega2560 -c arduino -P /dev/ttyUSB3 -b 9600

...but the only reaction I get is ...timeouts...

I have no clue what to do next.

How can I devide the things which are working so far from those
which are not working.

The ATmega2560 board is working - I can flash it via buspirate (ICSP).
I burned a bootloader with that...just to mention...not wanting to 
start an Arduino discussion on a Gentoo mailinglist...only to
explain the context a little bit...

What is the status of the ch340/ch341 driver?
(I am running kernel 4.12.3 vanilla right off Linus desktop so to
say...)

Thanks a lot for any help in advance!
Cheers
Meino

I'd like to buy into that explanation and have done that once or
more.  But on this particular install I was pretty careful about
making sure boot was mounted... and mounted from within chroot too.

No, I think the `Senior Moment' excuse is more forgiving .. hehe.
