Program expects data flash from the device for checking if it's in LDROM

Eleaf released firmware version 1.01 for the iStick Pico today.
Now you can upload a logo with the dimensions 96x16px.
"evic-usb upload-logo" shows the following errormessage:

`$ evic-usb upload-logo musik234-96x16.bmp

(Moved from: ClockSelect/myevic#229)
I packaged python-evic for aur:
https://aur.archlinux.org/packages/python-evic-git/

For autosync on connect:

    {
        echo '[Unit]'
        echo 'Description=Evic RTC sync'
        echo '[Service]'
        echo 'ExecStart=/usr/bin/evic-usb time'
        echo 'RemainAfterExit=yes'
    } > "$pkgdir/usr/lib/systemd/system/evic-usb-rtc-sync.service"

    {
        echo "# HIDAPI/libusb RTC Sync"
        echo 'ACTION=="add", SUBSYSTEM=="usb", ATTRS{idVendor}=="0416", ATTRS{idProduct}=="5020", RUN+="/usr/bin/systemctl restart evic-usb-rtc-sync"'
    } > "$pkgdir/usr/lib/udev/rules.d/99-nuvoton-hid-rtc-sync.rules"

AFAIK external service for sync time is needed only for systemd systems, as systemd add some restrictions to udev and evic-usb can't see device if running as script in udev.

JFYI, you can close this or say me for do a pull request. Thanks.

I was implementing verification for evic-sdk binaries and I found out that the verification in python-evic is not fully compliant with the original updater. This is not some high priority issue, just a heads up.

First, the official updater checks for "Joyetech APROM" as a sequence of bytes (no null terminator required), just like python-evic does. But the string needs to start at least 26 bytes from the end of the file (i.e. there must be at least 25 bytes after the 'J'). The second check, that python-evic also does, is for the device string ("E052" for the eVic VTC Mini). This must start at least 9 bytes from the end of the file.

Immediately after the device string there are three bytes. Let's call them, in order, A, B and C. Those encode the hardware version A.BC (e.g. 01 02 03 -> 1.23). This is the maximum hardware version supported by the firmware and is checked to be greater than or equal to the device hardware version. It makes sense since the display driver defaults to SSD1306, so newer hardware versions with SSD1327 would not work with older firmwares.

In my opinion the at-least-X-bytes-from-end thing is not really important, but the hardware version verification could be nice to have.

Hey, might just be me, but i'm stuck between $ python setup.py install and running evic

I keep getting an error that "evic" does not contain a main module. :<

I've been experiencing problems with the last revision when using dump-dataflash:

$ sudo evic dump-dataflash -o a.bin

Found device:
    Manufacturer: Nuvoton
    Product: HID Transfer
    Serial No: XXXXXXXXXXXX

Traceback (most recent call last):

UnboundLocalError: local variable 'aprom' referenced before assignment

I'm attaching a patch that fixes the issue (also args.dataflash needs to be checked for existence as it won't be set with dump-dataflash). I don't know if I'm the only one having problems with it, but it shouldn't hurt anyway.
Renamed to .txt, otherwise Issues wouldn't let me upload it: unbound-local-fix.txt

Hi, thanks for this!

upload -d is explained as

Use data flash from a file.

But it seems that without -d, with or without -e or -u, the upload command always uses a file, so it's unclear what the difference is.

Also, while I have a firmware image to upload, I don't know if it's encrypted or not. Is there a simple way to determine that?

Thanks for any help.

Mod is not being recognized over USB. I installed python-evic, cython, libusb-1.0-dev, hidapi and udev rules. I've also tried different USB ports and cables. Using Ubuntu 16.10 with kernel 4.9.0

Is there extra vendor codes or rules udev needs that I'm missing?

@netman69 I'm opening this as a separate issue for better tracking.

Did you have the correct headers installed? On opensuse the packages you need for cython-hidapi are: libusb-1_0, libusb-1_0-devel and libudev-devel.

Works as expected except it has to run twice. The device is then unusable unless a second evic-usb upload is issued, which allows using the updated device.

This is not really an issue. Or maybe it's an issue in Readme.rst. I've successfully flashed the newly released OFW 1.01 to my iStick Pico:

Hello! Thanks for your work!

I spent almost 6 hours trying to fix that, installing dependencies etc but no success.

Install script just gives me a bunch of errors about hid.pyx and hid.so, and in the end of output - ImportError: /usr/local/lib/python2.7/dist-packages/hid.so: undefined symbol: libusb_open.

Somehow I managed to solve these but I have recieved that:
from pkg_resources import load_entry_point
File "build/bdist.linux-x86_64/egg/pkg_resources/init.py", line 3138, in
File "build/bdist.linux-x86_64/egg/pkg_resources/init.py", line 3124, in _call_aside

pkg_resources.DistributionNotFound: The 'hidapi>=0.7.99' distribution was not found and is required by evic

So, I guess the problem is somehow connected with hidapi. I tried different versions, tried cython-hidapi etc .

I get this, don't ask me why it happened (short of that I was uploading self-built stuff, I have no idea):

Verifying data flash...OK
    Device name: eVic-VTC Mini
    Firmware version: 0.00
    Hardware version: 42949672.95

Please set the hardware version.

...indeed, that's exactly what I'd like to do in this situation.

After looking for options to do exactly that and finding none I downloaded the dataflash, changed the ffffffff starting at byte 4 to 63000000 (i.e. hw version 1.04, which is the correct one), uploaded that with extensive --no-verify (why do I also need to upload an aprom with that? no matter)... and it's not changing a thing.

Any hints, pointers, or insights?

I have python-evic installed on linux mint 17.1
The old version "evic convert ..." and "evic upload ..."worked.
After pulling the update "evic-usb upload ..." still works.
But now "evic-convert", "evic-usb dump-dataflash" and "evic-usb upload-logo" are showing errors:
evic-convert ...
evic-convert.txt
evic-usb dump-dataflash
dump-dataflash.txt
evic-usb upload-logo
upload-logo.txt
To be honest, my linux skills are quite poor, so I don't know what to do.

Thanks!

I'm on Arch Linux and installed via the python-evic-git PKGBUILD in the AUR.

Plugged in, ran evic-usb dump-dataflash -o out.bin:

The screen on the device seemed distorted, but that may just be the new style. I tried evic-usb screenshot -o screenshot.png, but it just hung after

Thanks again for enabling me to easily flash this without Windows!

If I try to upload any firmware (tested with both eVic and Presa firmwares), the device disconnects during reset. I have the Presa FW installed right now, but it also happens with the eVic one.

$ sudo evic upload somefirmware.bin

usb.core.USBError: [Errno 19] No such device (it may have been disconnected)

After this obviously it won't work, but it can be brought back to life with the official updater. I worked around this by adding a try/except to the call to dev.reset_system() in cli.py, ignoring the exception. It works fine now, with all kinds of firmwares. Actually, the device disconnecting during reset should be expected. I'm not sure this is the best way to fix it, though.

Hi,
is it possible to upload the arctic fox custom firmware using python-evic on linux?
