Firmware release 1.7.1.b1

mcook

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?

@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

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

@mcook
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

livius

@daniel
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

jmarcelino

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

jmarcelino

@daniel
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...

livius

@jmarcelino
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

jmarcelino

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

livius

@jmarcelino
what you got when you do?

import wifi
dir(wifi)

if above raise error
try to create empty wifi.py file in lib and back with result - i am really interested :)

livius

@jmarcelino
i tested this self
and whithout file wifi.py anywhere
i have interesting result

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

can someone confirm this?
And maybe @daniel can bring light about purpose of that module

mcook

@jmarcelino

Thank you. I downloaded the latest compiler, removed all of my old stuff and re-installed it all, and now it builds fine.

Mike

robert-hh

@livius I created a brand new firmware, and loaded that: no module wifi.
BUT: If I update via the pycom updater, there is a module wifi included.
So it's sneaking in via the "official" image.

daniel

@livius and @robert-hh thanks for the help. We found the offending file and a release without the problem will be out within 1 hour.
