webserver (?) crash
by Greg D. 21 Mar '18

21 Mar '18

Hi folks, Ok, so the new code seems to be working half-way decently. But I think there's a memory issue with the webserver. After poking at home and status a couple of times, my browser (chrome or Firefox) drop from a nicely formatted screen to something very text-like. Links and words, no buttons. Then another poke or two and the module crashed. I've done it a few times, and the crash usually seem to be with the Status button, which, looking at the console, seems to have an auto-repeat on it. I managed to get the repeated "job queue overflow" once, followed after hitting home a few times, a similar crash as below. This was one of the quicker crashes (browser didn't get to the text-mode state), using AP mode wifi. Browser in this case was Chrome. I have a suspicion that the issue with the text-mode stuff is a leak somewhere triggered by Firefox, with its CSS fetches.

Things left to do, before production
by Mark Webb-Johnson 21 Mar '18

21 Mar '18

All components have arrived, and final assembly is happening now. Next week will be firmware flashing, QC, and then packaging. Label looks like this: Last things to do, with the goal of making this as easy as possible for the first guinea pig end users… Modem Stability. I’ve been working on this. Seems ok now; I drive in and out of zero coverage areas often, and it seems to recover. I’ll address any new issues as and when I find them. It would be helpful if others could put these in their cars, and feedback good/bad news. Module Password (via web interface). I’ve asked Michael to handle this, if he has time. Tidy up of ‘secure’ mode. I’ve asked Steve to handle this. OTA. It is workable at the moment. Not automatic, but pretty usable. I’ve committed my last change today so that ‘ota status’ shows the version available on the server (if wifi is up). It would be nice if the web interface could help with this; and particularly nice if we could upload firmware via the web interface directly to flash. I think Michael is working on this (at least the help, if not the upload). Deadline for the above is this Sunday (18th March). End-User Documentation. This is priority now, and deadline is the end of this month to have something good enough for someone to follow to setup the module from scratch. The other production and Fasttech side of things is being handled. We’re gonna have the Fasttech US$20 coupon codes ready to go at launch. Hologram have also offered a US$5 coupon code as a starter for OVMS users (both new and existing), which will be ready at launch as well. Developers can benefit from both. Fasttech will have 100 kits (50 US, 50 EU) and I’ll have 20 (10 US, 10 EU). Normal orders can go through Fasttech - if people need something special (just modems, just main boards, etc) let me know and I’ll handle it directly. So, for me it is now on to end-user documentation. As a reminder, that is in google docs and everyone is welcome to join in and help. The link to view/comment on the document is here: https://docs.google.com/document/d/16JrXR7rybp-18DrEoeh1rg6GqQT_jVBvhaXh2oE… If anyone wants to help directly edit/author some of it, let me know your eMail address and I’ll send an invite with editing privileges. Regards, Mark.

NetManTask created twice
by Stephen Casner 21 Mar '18

21 Mar '18

Mark, I'm looking for the memory allocated to nonexistant tasks. In my code I added a call to AddTaskToMap() after the creation of the NetManTask. Now I see that the nonexistant task holding 264 bytes was an earlier instance of NetManTask. Do you expect it to be created, killed, and created again? I'm considering making a public function that will query the task list to populate the TaskMap, same as what is done now when the module memory or module tasks command is invoked. Then I would add some calls to that function at one or more places in system startup to try to capture the other unnamed task while it exists. Any suggestions for where to make such a call? The output below is with the aforementioned AddTaskToMap() call added plus some changes in ovms_module to list the tasks in module memory in task number order so the order is consistent from one run to the next and with the nonexistent ones first and marked with asterisk. I can commit these changes if that is OK at this point. -- Steve Free 8-bit 31760/283148, 32-bit 27588/55864, SPIRAM 0/0 --Task-- Total DRAM D/IRAM IRAM SPIRAM +/- DRAM D/IRAM IRAM SPIRAM no task * 5276 0 0 0 +5276 +0 +0 +0 main * 40076 0 0 0 +40076 +0 +0 +0 3FFE5CDC * 0 1396 0 0 +0 +1396 +0 +0 NetManTask * 0 264 0 0 +0 +264 +0 +0 esp_timer 55112 0 644 0 +55112 +0 +644 +0 eventTask 0 7620 0 0 +0 +7620 +0 +0 ipc0 10848 0 0 0 +10848 +0 +0 +0 ipc1 12 0 0 0 +12 +0 +0 +0 Tmr Svc 0 27808 0 0 +0 +27808 +0 +0 Housekeeping 17488 50384 0 0 +17488 +50384 +0 +0 tiT 128 1640 0 0 +128 +1640 +0 +0 AsyncConsole 0 20 27488 0 +0 +20 +27488 +0 mdns 0 112 0 0 +0 +112 +0 +0 wifi 0 1612 0 0 +0 +1612 +0 +0 NetManTask 4 2200 0 0 +4 +2200 +0 +0

3.1 QC checks
by Mark Webb-Johnson 20 Mar '18

20 Mar '18

In production/qc/production_notes.txt we have the current production/qc notes (for China). Please look over those, and let me have any suggestions for anything to be changed / added? Deadline for submission is tomorrow morning (Asia time). It would be good to include a GPS test. Any ideas for how to do this - manually enabling the GPS? It can be a ‘simcom muxtx’ command if that helps (as check #6 has the modem up and ready). Regards, Mark.

Command prompt in secure mode
by Stephen Casner 19 Mar '18

19 Mar '18

At Mark's request I have implemented a change to the command prompt after switching to secure mode: OVMS > ena Password: Secure mode OVMS # As implemented in this commit, the color also changes from green to red, but that is only a proposal. I also looked at blue, but on my terminal it's not so distinct from black. If preferred, we can have both modes be green. Actually, as I thought about this, I wondered whether our console welcome banner and prompt should be different from green since all the info-level log messages are green. But there are not many ANSI color choices and they don't look the same on all terminals, so we can't get carried away with this. -- Steve
