MYSBootloader 1.3pre2 testing


  • Admin

    Hi all,
    Here is the second pre-release of MYSBootloader 1.3 for testing purposes.

    Download here. Thanks for your feedback.

    MYSBootloader 1.3pre2 (1.3NS)

    • requires MySensors 2.0.x
    • supports OTA FW AND serial FW updates
    • no external flash needed for OTA FW updates (thus, offline update)
    • communicates via assigned parent node (if found)
    • 2kb bootloader size
    • bootloader commands removed (size constraints, STK500 code instead)
    • nRF24 (Channel 76, base address 0xA8A8E1FC00, data rate 250kbs)
    • serial uploads: 115200 baud (16Mhz), 38400 (8Mhz) or 9600 (1Mhz)

    Using Arduino IDE 1.6.12:

    Please read this excellent guide written by @scalz about MySensors OTA programming.

    In brief:

    Copy bootloader *.hex files (from Bootloader folder) to the [Arduino IDE installation folder]/hardware/arduino/avr/bootloaders/MYSBootloader/

    Restart Arduino IDE, choose under Tools | Board | ATmega328 with MYSBootloader |, select correct board under Processor tab. Connect USBasp to sensor node and select Tools | Programmer | USBasp and hit "Burn Bootloader"
    Please use the AVR fuse calculator to retrieve the individual fuse settings. If you need to change frequency, BOD or other settings, change the fuse settings based on the fuse calculator.

    OTA FW updates using MYSController 3315 (included) (refer to @scalz's guide😞

    Copy Arduino FW .hex file to MYSController/Firmware folder and edit firmware_config.csv file according to the existing lines.

    Hit "Refresh Repo" in MYSController and the newly copied firmware should appear in the Assign FW dropdown list, ready to be uploaded.

    Read this thread for discussions on MYSBootloader 1.3pre1

    Have fun!



  • Flashed one of my boards with new bootloader. Signing fails. Uploaded and ran the personalisation again and then the original sketch, still "signature verification failed".

    Edit, Went back to standard bootloader, cant get signing to work again. Hm. Doing something wrong maybe.

    Edit 2, got it working again. Flashing bootloaders, clearing eeprom, personalisation, doing it many times and at last it started to work again with (soft) signing enabled. Have not been able to upgrade my sketch using OTA yet..

    How would I configure the boards.txt for my boards with 3.3v, 8MHz and 8MHz external crystal? I'm really new to all this. Never worked with arduinos before and I don't fully understans the fuse calculator yet. 😉

    @NiklasO you can use the internal RC oscillator (that is 8Mhz), no need to use external XTAL. For AVR fuse calculator, refer to http://www.engbedded.com/fusecalc/ or http://eleccelerator.com/fusecalc/fusecalc.php?chip=atmega328p and the documentation therein.

    I read somewhere that there has been a wireless bootloader for the RFM69 "under development" now for some time, and that it can work without using additional external memory chips (such as a winbond memory chip). Is that true, and if so, has the development completed or is it still unreleased?



  • @tekka

    Finally some action here again! Yeah!
    Any chance we can get our hands on the source so that we can change channels/power and finetune led status and such?

    I don't understand the fusecalc yet. I don't know all the terms used on that calc page or how it really works but I'm learning I guess. 😉 The Pro Mini clones i got from eBay has this extremely small external 8 MHz (for 3.3V) and 16MHz (for 5V) crystal/oscillator/resonator or what they are called. Why is it there if not needed? Genuine interested here.


  • Hero Member

    So, I gather there is no RFM69 version?



  • @mannkind what other software do you use for ota firmware update?
    thanks


  • Hero Member

    Not getting an answer here. Should I be asking the question somewhere else?



  • This post is deleted!


  • @mannkind thank you for your reply. I don't want to get you in trouble regarding the rules. i don't feel it is against the rules to promote open source or contribution around mysensors if it makes the journey more enjoyable. maybe a mod or admin can pitch in and clarify in any case.
    I understand that the gateway role is to open up integration with other controllers (and we have quite many thanks to that)
    The problem i am trying to wrap my head around is to have mysensors network attached to my current controller, and ideally be able to update over the air the sketches. how can i begin doing that? i am ready to use 2 or more controller (mycontroller or myscontroller or...), 2 ore more gateways and even maybe have the nodes on two different rf channels.

    Basically, what is the recommended way to achieve that, while having for the time being at least, another controller attached.?



  • Hello! Will there be a chance to change the radio channel used for the bootloader OTA process?



  • @mannkind : thank you for your message. I'll give that a go later on.

    @tekka , @anyone 🙂
    I am trying to make this work using MYSController (from MYSBootloader_V13pre2/). I've followed the instructions above from @tekka, but it feels like the OTA process kicks around quite quick, then it seems to block in a loop

    I'll try to keep it going all night, but here are my full log till now.
    Any idea what is going wrong?

    @jmkhael Looks like a bad radio connection (GW too close / far, interference, power) What happens if you upload the FW via serial link?



  • @mannkind : thanks for the clarifications. My problem is that the node seems to hang at the booting phase in MYSController sa per the screenshot.

    @tekka that should be it (gw in the 50 cm range). I'll try more tests and get back here in any case.

    @mannkind, @tekka: How do we interpret the OTA logs?

    0_1476786275039_MYSController 1.0.png



  • @tekka: it was probably a mix of power/distance. when change these two parameters, OTA went fine. thank you

    What is the best way to handle OTA for sleeping nodes? is there something else todo besides setting the property under settings in MYSController? Do I need to powercycle the node or will MYSController kicks in when the node sleeps/smartSleeps?
    thank you for your time


  • Admin

    @jmkhael MYSController will reboot the node as soon as it wakes up, sends and processes incoming messages.
