New firmware release 1.10.0.b1 (External 4MByte RAM support)

[robert-hh]

@daniel Building fails at load time (and yes: new compiler version, new esp-idf version) with the error:

LINK build/LOPY_868/release/application.elf
/home/robert/Downloads/xtensa-esp32-elf/bin/../lib/gcc/xtensa-esp32-elf/5.2.0/../../../../xtensa-esp32-elf/bin/ld: cannot find -lpthread

application.mk:375: recipe for target 'build/LOPY_868/release/application.elf' failed
make: *** [build/LOPY_868/release/application.elf] Error 1

Where's the missing stuff?

[daniel]

@robert-hh thanks. We will update the docs shortly. Regarding the build error, I have just added the missing libraries: https://github.com/pycom/pycom-micropython-sigfox/commit/f81fb9aebc0d970d7c8bfe3896fa0fe7981d7475

That should fix it.

Thank for the update. A couple of question:

1. does this idf version fix the connection problem?
2. in frozen folder i found MQTT client. Can we have documentation for this new modules?

It's the same code found at https://github.com/pycom/pycom-libraries/tree/master/examples/aws which is documented at https://docs.pycom.io/chapter/tutorials/all/aws.html

i'm interested to this too

[affoltep]

The new firmware seems to use more memory again. My code is not running anymore :(
I need a simple way to downgrade to the version before...

You can find downgrade instructions here. Please use the following download links for the previous version:

• 1.9.2.b2: SiPy, LoPy 868, LoPy 915, WiPy 2

[robert-hh]

@daniel This is nothing directly affecting xxPy, but maybe useful observations for the future:
I tried to load the WiPy image to a LOLIN32 and a LOLIN32 Lite.
a) For both, the automatic enabling of pulling GP23 low does not work any more. Changing a line in application.mk to:
ESPTOOLPY_SERIAL = $(ESPTOOLPY) --port $(ESPPORT) --baud $(ESPBAUD)
made it working again.
b) The firmware does not run any more on the LOLIN32 Lite, which has a ESP32D0WDQ6 (revision 1) chip.

@daniel

Looking into the diffs, it looks like you also addressed the glitch between OTA and USB loads.

No, you did not. No problem, just important to know.

[affoltep]

@xykon Thx, Xykon

I just realized that it may has a context with the new deepsleep functionality of 1.10.0.b1. Does the deepsleep shield lib 1.0.1 need to be updated?

[crumble]

As some others I have problems to connect via USB after this update. I have a LoPy mounted on a PyTrack. Both with latest firmware. The host is Win7 running Atom with the Plugin before the change with the splitted sync button.

If the timing is right, data will be send from the LoPy to the PC. I can see output from my main.py and the REPL with the prompt.
The other direction seems not to work. Typing will not show echo from the LoPy. Selecting reconnect or the "show version" does not work.

To see the output I have to deinstall the PyTrack in the device manager and hope that reinstall is ready before the prompt is send.

Have you changed the default settings for the serial?

[daniel]

@robert-hh the reason the board doesn’t automatically programs anymore is because we added the no_reset options to the command line arguments of esptool.
Probably the software doesn’t run anymore because it’s trying to initialize the pSRAM in a device that doesn’t have it fitted. The new firmware uses the chip revision to decide if it’s a gen1 or gen2 of our boards.

Cheers,
Daniel

@daniel said in New firmware release 1.10.0.b1 (External 4MByte RAM support):

Add .voltage() method and calibration functions to the ADC class.

Please update the Pycom docs about this new calibration method to the ADC. Many people want to use the ESP32 ADC with better readings.

@daniel First, thanks for the update! I was just asking about freezing main and boot, having _main.py should make it even easier.

There is one thing I noticed though: when flashing or erasing the chip, the script gets stuck at "Staying in bootloader" and then crashes. However, the chip gets erased or flashed (depending on the command) even though the crash occurs so it is not really affecting the process. I guess it just doesn't hard reset like before.

[hay4to]

with the new update the machine.reset() call block the board.
[edit] the board run a pure version of the new release, updated via Pycom firmware update

[daniel]

@affoltep can you be more specific? The new firmware has the same amount of MicroPython heap available as before (67K). What is the error that you are seeing in your app?

Cheers,
Daniel

[daniel]

@hay4to thanks. We will investigate this.

@daniel I'm getting the following error while trying to boot

do you have reproductive test case?

prvProcessReceivedCommands

@daniel interesting which path in xTimerGenericCommand return this failed response

[ssmith]

@livius I haven't tried to narrow it down yet. This occurs while trying to load our whole application. Has something changed with the timers?
