Latest Firmware Free RAM @ 37K ?



  • Am I right in saying that the free RAM is now down to 37K from what was reported here to be 79K

    https://forum.pycom.io/topic/170/lopy-wipy-2-esp32-specs-and-performance

    dhcp server start:(ip: 192.168.4.1, mask: 255.255.255.0, gw: 192.168.4.1)
    (sysname='WiPy', nodename='WiPy', release='1.4.0.b1', version='v1.8.6-398-g4a4a81e on 2017-01-20', machine='WiPy with ESP32')
    stack: 720 out of 7168
    GC: total: 37952, used: 5360, free: 32592

    MicroPython v1.8.6-398-g4a4a81e on 2017-01-20; WiPy with ESP32
    

    If so this is less than 50% of what it was before, or am I misinterpreting something ?

    It seems that I just can't run many of the libraries that ran successfully on the WIPY1 and are struggling to put together more than 1 or 2 libraries to create a complete solution ?!

    Update

    I just ran the same test on 0.9.0b and got 192k free.

    >>> print(os.uname())
    (sysname='ESP32', nodename='ESP32', release='0.9.0b', version='1f7bdfd on 2016-10-09', machine='WiPy with ESP32')

  • Can you guys confirm on which release it would be fixed as i wanted to showcase a demo as of now i am not even able to test a small program 😟



  • @crankshaft said in Latest Firmware Free RAM @ 37K ?:

    It's just not enough, I cant even get a relatively simple MQTT client and a BMP280 sensor working due to lack or ram !

    Agree, it is not enough, it is far below expected according to initial KickStarter announcements and amount expected based on ESP32 data sheet. According to Daniel's comments PyCom is waiting for chip vendor to fix issues and one can expect cca. 98k free RAM once upon a time. Well, you can say it is also less than what you need and less offered by few otherwise less sophisticated boards.

  • Well, for LoPy it is only 32k. Be happy with 37k!
