  Hmm I don't remember ever having to use elevated privileges to run dfu-util, but I'll add it to the documentation, it could be a solution for some people! Thanks Gijs

  I am unsure what i did as i could have sworn i did this already, but i tried it again with wiping the filesystem and resetting the config and things seem to be working again.

  r means 'release' where 'rc' stands for 'release candidate'. The 'b' label is used for 'beta' releases not meant for production environments. I recommend to use the latest available 'r' or 'rc' release (whichever is latest), currently that is 1.20.2.r4, when describing any issues, or specifically mention you're running a beta firmware for testing.

  @Dylan as @Gijs wrote, it’s obvious from the output that the module didn’t connect to the WLAN. What is weird is that even when it works you don’t have the Network found! output. Are you running the same code on both? If the first log comes from a device actually running the code you gave, it means it didn’t find the network. Try logging all networks found to check for a typo of some sort, or loop around scan (with a small sleep) until you find it.

  @Gijs the modem manufacturer gives pycom no notes on what they are giving to you? that seems weird. I assumed the stability notes are what the manufacturer told Pycom but thats not even the case - you are saying you have no clue what the changes are but through manual testing yourselves? How is this okay?

  @lmerza What do you expect as the result? If you just call pycom.bootmgr(), the actual boot setting are reported.

  @lmerza After update. If at that moment to he file system is not switched, change the setting and reboot. During reboot the new filesystem will get active. Since switching to the FS which is already set does not change anything, you can just set LittleFS and reboot. Sobthe sequence is: save files, if required update firmware reboot set FS to LittleFS reboot restore the files

  To be honest I have never tried the Lorawan OTA firmware update, so I cannot say if it is in working condition. I think the page is mentioning the readme is 'coming soon', but the OTA firmware update looks like it should work, per the documentation page. Let me know if you're able to get it working! Gijs

  @robert-hh said in ticks_ms() return big value at startup with custom firmware: gettimeofday() Which brings me to my other question of do you know why gettimeofday() isn't available in userland?

  @Manuel-Ricardo-Alfonso-Sanchez I do not see whther this was discussed already, but which TTN server do you have configured. There were people which had problems because the join accept message from the TTN server arrived too late at the gateway. And you have some TX messages in the server log which have been rejected being too late. so you could try to use other server URLs.

  Pycom firmwares with single/double precision and ulab module

  @rcolistete this is really great work - I've been tempted to try a ulab port to pycom chips but didn't think I'd have the technical depth. What is your plan to keep updating these? Alternatively are you able to share source code and marked changes (especially micropython v1.12 back port) to allow me to continue doing this custom build with ulab and dp? The reason I ask is that Firmware Release v1.20.2.r2 has some LTE fixes I need so I'm hoping to apply this to the latest firmware
