This type of crash is the reason I now build the edge version on dexters-web.de without CONFIG_WIFI_LWIP_ALLOCATION_FROM_SPIRAM_FIRST. It seems to reduce these crashes, but I haven't done new statistics yet. Craig, you could also try if that helps for you. Regards, Michael Am 27.06.19 um 04:11 schrieb Mark Webb-Johnson:
Hard to see from the logs. It certainly seems like a watchdog initiated reset, but the backtrace shows it in the ip stack. What you are seeing is not at all normal, and seems to be periodic.
You can rule-out the vehicle module as the cause of the problem by simply turning off the vehicle type, so no vehicle module is loaded at startup. Then see if it still crashes. Similar for server connections (are you using v2 or v3?).
Regards, Mark.

I've been running a v3.1 module in my Cadillac for a few weeks now and recently realized that it crashes frequently. I see this on the status page:

I was beginning to think that my battery tender maintenance charger was the cause but I disconnected it a few days ago.
Is this psram cache issue related or something else? I haven't written much code yet and it doesn't do a lot, especially when the car is off.
Is there an easy way to poll the module for crash related info?
I never understood what the boot reason numbers were:
Detected boot reason: Crash (8/14)
but I see now that there is a number for each core and are defined in the esp-idf/components/esp32/include/rom/rtc.h:
typedef enum { NO_MEAN = 0, POWERON_RESET = 1, /**<1, Vbat power on reset*/ SW_RESET = 3, /**<3, Software reset digital core*/ OWDT_RESET = 4, /**<4, Legacy watch dog reset digital core*/ DEEPSLEEP_RESET = 5, /**<3, Deep Sleep reset digital core*/ SDIO_RESET = 6, /**<6, Reset by SLC module, reset digital core*/ TG0WDT_SYS_RESET = 7, /**<7, Timer Group0 Watch dog reset digital core*/ TG1WDT_SYS_RESET = 8, /**<8, Timer Group1 Watch dog reset digital core*/ RTCWDT_SYS_RESET = 9, /**<9, RTC Watch dog Reset digital core*/ INTRUSION_RESET = 10, /**<10, Instrusion tested to reset CPU*/ TGWDT_CPU_RESET = 11, /**<11, Time Group reset CPU*/ SW_CPU_RESET = 12, /**<12, Software reset CPU*/ RTCWDT_CPU_RESET = 13, /**<13, RTC Watch dog Reset CPU*/ EXT_CPU_RESET = 14, /**<14, for APP CPU, reseted by PRO CPU*/ RTCWDT_BROWN_OUT_RESET = 15, /**<15, Reset when the vdd voltage is not stable*/ RTCWDT_RTC_RESET = 16 /**<16, RTC Watch dog reset digital core and rtc module*/ } RESET_REASON;
so my most recent reset was due to 8: "Timer Group1 Watch dog reset digital core" (and the 14 is probably cpu0 resetting cpu1 when the watch dog hit?) I am using Ticker10 based on Ticker1 code I saw in vehicle_nissanleaf.cpp. But I get crashes even if I ifdef out that code out.
I've also attached a screen grab from my hologram.io account, I think it's showing just how frequently the crashes are.
I could also eliminate my FreeBSD xtensa toolchain by doing a build under ubuntu, would that be worthwhile?
