OVMS v3.1 crashes during boot continuously

Hi. I ordered my OVMS v3 module in march 2018, and excited when I received it months later. The module has been connected in my Kia Soul EV from around version 3.1.004, with OTA updates enabled, until July 12. It was connected to dexters-web.de V2 server. It usually reported data to the app, sometimes with long delays, at other times not at all. From July 8th to July 10th, I drove the car 1450 km from Copenhagen to Paris, then parked it. When I tried to unlock the car 5 days later, the 12 Volt battery was completely drained, and since then, the OVMS has neither connected, nor sent beacons for the WIFI AP after a factory reset. I have no idea what happened. To my knowledge the module was functioning normally when I parked the car. On dexters-web, I can see that the last update was received at 22:07 12.07.2018. I have now (today) installed the development tools and OVMS software, built, and captured the output from the continuing crashes, when booting on the current master: Henriks-MBP:OVMS.V3 henrik$ make simple_monitor --- forcing DTR inactive --- forcing RTS inactive --- Miniterm on /dev/tty.SLAB_USBtoUART 115200,8,N,1 --- --- Quit: Ctrl+] | Menu: Ctrl+T | Help: Ctrl+T followed by Ctrl+H --- make: *** [simple_monitor] Terminated: 15 Terminated: 15 Henriks-MBP:OVMS.V3 henrik$ make monitor MONITOR --- WARNING: Serial ports accessed as /dev/tty.* will hang gdb if launched. --- Using /dev/cu.SLAB_USBtoUART instead... --- idf_monitor on /dev/cu.SLAB_USBtoUART 115200 --- --- Quit: Ctrl+] | Menu: Ctrl+T | Help: Ctrl+T followed by Ctrl+H --- ets Jun 8 2016 00:22:57 rst:0x1 (POWERON_RESET),boot:0x3f (SPI_FAST_FLASH_BOOT) configsip: 0, SPIWP:0xee clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00 mode:DIO, clock div:2 load:0x3fff0018,len:4 load:0x3fff001c,len:4796 load:0x40078000,len:0 load:0x40078000,len:14896 entry 0x400785) spiram: SPI RAM mode: flash 40m sram 40m I (655) spiram: PSRAM initialized, cache is in low/high (2-core) mode.2mI (656) cpu_start: Pro cpu up.

Or can I somehow fix the module (if so; how)? Is it possible that the OVMS malfunctioned, and the repeated re-booting caused extensive power drain, either directly from the OBD-II, or by somehow keeping some systems in the car “awake”, via CAN-bus activity?

Hi, In order to help understand the current status of the Nissan Leaf support a Vehicle Feature List wiki page has been created. As I don't have access to an OVMS the Leaf entries are only what could be gleened from the code. Please feel free to contribute/correct as you see fit.

Porting code from v2 to v3

Hi, I am working on the Think City EV code and have some questions.- what is the best way to signal that the charging connector is plugged? ms_v_charge_pilot?previously it was cardoorbits1. - what is the best way to compare OvmsMetricStrings? Or should I dublicate the state in an enum and use that? - what is the best way to compare the OvmsMetricFloat to a literal float? - what is the current way of doing net_req_notification Thanks in advance,Nikolay On Tuesday, July 17, 2018, 3:37:49 AM GMT+2, Mark Webb-Johnson <mark(a)webb-johnson.net> wrote: Jacob, > Is there a reason why OVMS bundles three different SSL libraries?

Primarily because we wrote those before we included mongoose into the project. But also because the mongoose http_client code sucks. It reads the entire message body into RAM, before passing it on to the client; that just won’t work for something like a firmware image. To complicate the choice further, ESP now includes a esp_http_client in their latest 3.x IDF (which wasn’t there before). I did try to convert our TCP and HTTP client libraries to mongoose a while ago, but failed. Those libraries are blocking (with i/o done in the context of the thread calling them), but the mongoose library is event-based non-blocking (with i/o output in the context of the calling thread, and i/o input in the context of the mongoose thread). Mongoose didn’t use to be thread safe, and that caused us all sorts of issues (now solved, by the work Michael and others did to make it thread safe). > IMO the best way would be to rewrite ovms_net and > ovms_http to use mongoose and configure mongoose to compile with SSL > support (probably mbedtls as the other two don't work). I agree. In general, I prefer the mongoose approach, and we are trying to standardise on that (for good or bad). Probably the best would be to fix the http client in mongoose to work properly (or at least have an option to deliver the body block by block as they arrive), then convert our stuff that uses ovms tcp/http libraries, then drop the tcp and http libraries. Not trivial given the different models (blocking vs non-blocking events). Between openssl vs mbedtls, I don’t really care. I think we’re going to have to manage certificate loading ourselves anyway (as we need to load from a combination of statically defined (in flash using COMPONENT_EMBED_TXTFILES and asm(“_binary_* start/end) and dynamic (in /store/tls/trustedca/* or somewhere like that).
