Firmware release 1.7.1.b1

daniel

Hello,

A new firmware version 1.7.1.b1 has been released.

Here's the change log:

Add support for LoRaWAN class C devices.
Fix issue with Bluetooth client not using the correct connection id.
Add support to select the RTC source clock.

The options now are the internal 150KHz RC clock or an external 32KHz crystal.
Add TX_FAILED_EVENT for LoRa

Also, the TX_EVENT for confirmed packets is only raised when the
acknowledge is received, otherwise the TX_FAILED_EVENT is raised.
Allow to send packets with more than 64 bytes on raw LoRa.
Register LoRa and Timer Alarm callback handlers with the GC root pointers.
Remove all logs messages from the IDF sent to UART0.
Add all IRQ handlers to the GC root pointers.
Set the correct stack limit on the IRQ thread to (stack_size - 1024).
Update to the latest IDF and add support for the 4MByte pSRAM on the OEM modules.
Fix timer alarm memory allocation bug during initialisation.

All the sources have been pushed to the github repository as well: https://github.com/pycom/pycom-micropython-sigfox

Cheers,
Daniel

@daniel Making runs in unresolved libs:

micro-ecc
jsmn
soc
I freshly cloned pycom-esp-idf to overcome compile errors, but these libs are missing during the link state.
So: Where do I get the libs from?

Update: So, libmicro-ecc.a is in the lib directory, only the Makefile for the bootloader needs a --Llib in the definition of B_LIBS. But still libjsm.a and libsoc.a are missing.
Update 2: Fixed with an update to the repository by Daniel

@daniel

Hi,

The previous code built easy enough... seems like this one's bootloader has some overlapping names defined already in IDF. Do you have any suggestions for how to build this version?

Thanks,
Mike

@mcook did you also clone the latest version of the IDF: https://github.com/pycom/pycom-esp-idf ? With the old IDF it is not going to build...

mcook

@robert-hh

I pulled again, and I got those libs.

Thanks, it went a lot further this time. I was able to build the bootloader. But it is failing while trying to build the app. Seems like a lot of it was completed.

I am getting a number of errors. Do you have any suggestions?

robert-hh

@mcook did you include the board name in the make, like
make BOARD=WIPY TARGET=app

mcook

@robert-hh

Yes. I did. I use the flash target to get it to write directly to the board.

make BOARD=LOPY LORA_BAND=USE_BAND_915 flash

@daniel
I have few new problems after upgrade from 1.6.13 to 1.7.1
Now many times i got

AttributeError: 'module' object has no attribute

but code was not changed and worked before upgrade - can something e.g. GC root pointers change affect some code?
I do not use custom threads. Only "simple" code.

UPDATE
After downgrade to 1.6.13 all work ok without any change in the code..

daniel

@livius: can you share a small piece of code that reproduces the issue that you are having? Thanks...

daniel

@mcook please try clonning the new IDF from scratch.

daniel

@livius can you share the complete exception log? Is it happening inside an interrupt callback?

mcook

@daniel

Hi. I did that.

These are my steps. They worked with the previous source. But now I am receiving the error. Do I need to change something?

@daniel

Is it happening inside an interrupt callback?

I do not use in this project callbacks and threads

i have tried to create minimal code to reproduce but still without success.
Maybe this help somehow - but probably not:
In normal case with 1.6.13 when it start this is the log

not sure if it helps but the latest toolchain is actually https://dl.espressif.com/dl/xtensa-esp32-elf-osx-1.22.0-61-gab8375a-5.2.0.tar.gz

i have found problem :) And now have question.

Is name wifi registered as reserved unit name?
i have in my lib folder wifi.py

but i see that when i call dir it list me some system objects?

>>> dir(wifi)
['Wifi', 'WLAN', '__name__', 'hexlify', 'sleep', 'Timer', 'exc_info', 'start_new_thread']

after changing wifi.py to different name and all its references
all work ok

@livius
Weird I didn't get any wifi.py on my lib and also nothing after os.mkfs("/flash") Wondering how you got it...

I was just reading this post about the 4MB pSRAM support https://www.esp32.com/viewtopic.php?f=13&t=2031

As Jeroen explains do we need to build the toolchain from the xtensa-1.22.x-ext_ram_patch branch to compile the Pycom source correctly for the W01/L01 modules?

All seems a bit cutting edge :-) but to get 4MB RAM wow...

This is my custom file.
And it worked ok in previous firmware.
but now this name is registered by system for something. I see nothing about in docs and i do not see it in pycom sources, but maybe i miss something in pycom sources

@livius
ha sorry misunderstood your comment. But if I do dir(wifi) as you showed I get nothing.
