Pytrack and Pysense firmware release 0.0.2

[daniel]

Hello,

We have released a new firmware for Pytrack and Pysense. The version is 0.0.2. These are the release notes:

• Add possibility to wakeup via the Pysense/Pytrack pushbutton.
• Correct the timing of the deep sleep cycles.
• Correct the generic read/write modify function to control the PIC microcontroller.

The instructions to apply the new firmware can be found in: ~~https://docs.pycom.io/pycom_esp32/pycom_esp32/toolsandfeatures.html#updating-pysense-and-pytrack-firmware~~

New link: https://docs.pycom.io/chapter/pytrackpysense/installation/firmware.html

We will publish the libraries to use the GPS and the sensors on the board tomorrow.

Cheers,
Daniel

How to upgrade under Windows?

[joe2612]

Some additional tips to help MAC users:

1. After downloading the Pytrack/Pysense DFU, rename it to firmware_file.dfu
2. Move the DFU file to Library folder
3. Hold the push button and connect the Pytrack/sense ( no LoPY etc needed) over USB
4. release the button and paste the command : dfu-util -D firmware_file.dfu
5. Should be good to go!

dfu-util is also available for windows http://dfu-util.sourceforge.net/releases/

dfu-util-0.9-win64.zip

Should be really similar to use (from command line)

The pysense is recognised by my Windows 10 as Serial USB device.

However, when I plug it in with the button pressed it says unknown device, no driver available.

Hence the update fails

I have tried it before i asked ;-)
But it say unknown vendor for me

I have tried also -s
dfu-util.exe -s COM4 -D pysense_0.0.2.dfu

But have not tried much. In the evening i will try more

@livius
Ha sorry I see Windows needs a DFU driver! No problem, libUSBk to the rescue.

Try installing the driver package I generated:
[now old, see above]

or install libusbK and make your own using the inf-wizard :-)

Once that's done dfu-util -D pysense_0.0.2.dfu will work (remember you only have about 7 seconds to run it after releasing the button, so install the driver first)

DFU-UTIL has to be >= version 0.8
Tested with PyTrack not sure if the PySense uses the same ID, will try it up later.

[daniel]

@jmarcelino thanks for the Windows instructions and the driver package!

[jmarcelino]

PySense and PyTrack DFU use different USB IDs so I generated two driver packages for Windows using libusbK (I don't know how to make a single one...)

PySense: http://metavurt.net/software/drivers/PySense_DFU.zip
PyTrack: http://metavurt.net/software/drivers/PyTrack_DFU.zip

After installing the driver you need download dfu-util for Windows from http://dfu-util.sourceforge.net/releases/dfu-util-0.8-binaries/win32-mingw32/ , I recommend the static compiled binary to avoid any library issues, you only need one executable: dfu-util-static.exe

Place the executable and the dfu firmware from Pycom together and get ready to run:
dfu-util-static.exe -D pysense_0.0.2.dfu or
dfu-util-static.exe -D pytrack_0.0.2.dfu depending on your firmware and board

Then connect the board with the button pressed down, release the button after one second and run the command above - remember you only have 7 seconds to do so!

The process will look like this

on macbook pro :
I advice to specify device since another device is in dfu mode

dfu-util -l
dfu-util 0.7

@jobbyworld
If you update to dfu-util version 0.8 or later it should pick up the correct ids from the file to filter on

[johncaipa]

@jmarcelino thanks for the instructions!
@daniel where can we find examples and libraries?
regards

i moved this wipy to expansion board and it work without any problem

[daniel]

@livius after it hangs, does it revive by resetting the WiPy 2, or do you have to power cycle the pysense?

[livius]

@daniel
it revive by pressing reset button on Wipy2
and back hang

UPDATE
pytrack is ok only pysense is affected

[jmarcelino]

@livius
No problem here with the Pysense (also upgraded using Windows) and a LoPy (sorry I don't have a WiPy to test)

Not sure how many checks the DFU stuff uses (would think it was reliable since it's a USB.org standard) but maybe try flashing it again?

[jmarcelino]

@livius
Does the Pysense after update appear as a USB serial device using the usbser driver?

I have tried before 5 times before written here
also with different cable on different USB port - no difference
and with really short cable (used for near everythin programing)
e.g. white cable below

Does the Pysense after update appear as a USB serial device using the usbser driver?

yes

[jmarcelino]

@livius
Sorry should have figured you'd have done that already :-)

Not sure what it can be, but if pressing reset works I guess it's the WiPy crashing and not the Pysense shutting it off. Sounds like that was the question Daniel had.

for us we can assume this always ;-)
