Deadlock on module reset
by Michael Balzer 13 Apr '20

13 Apr '20

Chris informed me my commit bfcb1be97bb8fbfda9913f9094ba71ef9c94c7e8 introduced a deadlock in the module shutdown. My tests showed it doesn't always occur. A first simple analysis of the locks set during shutdown shows there is a race between networking tasks reacting to the "system.shuttingdown" event and the events task processing the next ticker event. It seems the subsystems which registered for processing events try to deregister while still allowing to process the next event delivered, leading to the deadlock. I think fixing this needs a thorough rework of the shutdown deregistration processes. As the event mutex was meant to fix a potential race condition, I've reverted the change for now.

Flash memory and developement setup
by Eddy Vromen 12 Apr '20

HI All, I have a question about the flash memory of the ESP32. I read that the ESP32 uses 16Mb of external flash memory and in the schematics on page 27 there is a flash memory chip. However, in the latest v3.2 schematics there is no external flash chip. Am I correct to assume that the 16Mb of memory is on the module now? How does this impact the e-fuse settings? Another question that came up while setting up a development environment: The version of esp-idf thats used by the OVSM project uses the Mingw32 environment. Based on my limited exposure to using this environment, its very slow compared to compiling esp-idf code under e.g. platformio under VSCode. How are the core developers dealing with this slowness? Is it at all possible, if i could force platformio to use the correct the idf-esp libraries, to compile the OVMS code in a more recent environment that uses cmake and ninja? Thanks, Eddy

Hi! i want to create some log file with ovms and savvycan, but ovms all time crashed very often. i start the logging with the following command: can log start tcpserver transmit gvret-b :23 424 I now want only the 424 pid, i connect the savvycan with ip address (not direct to the ovms, with the ap both the ovms and laptop connected). I used the 3.2.011-169-g4b2f3c64/ota_0/eap fw updated automatically with ota from dexters-web eap.

HI All, Just jumped on the OVSM bandwagon! Ordered myself a board and downloaded everything i could download. I am now in the process of trying to compile the code. Followed the OVMS v3 Developer Guide to a T. Still, pretty far down the list it throws an error. I would be great full if someone could point me to a solution for this. The full log is attached. CXX build/main/ovms_events.o CXX build/main/ovms_http.o CXX build/main/ovms_console.o CXX build/main/ovms_boot.o C:/msys32/home/Eddy/Open-Vehicle-Monitoring-System-3/vehicle/OVMS.V3/main/ovms_boot.cpp: In constructor 'Boot::Boot()': C:/msys32/home/Eddy/Open-Vehicle-Monitoring-System-3/vehicle/OVMS.V3/main/ovms_boot.cpp:248:46: error: 'xt_set_error_handler_callback' was not declared in this scope xt_set_error_handler_callback(ErrorCallback); ^ make[1]: *** [/c/Users/Eddy/Desktop/esp-idf/make/component_wrapper.mk:290: ovms_boot.o] Error 1 make: *** [C:\Users\Eddy\Desktop\esp-idf/make/project.mk:552: component-main-build] Error 2 Eddy@DESKTOP-TIO8A3R MINGW32 ~/Open-Vehicle-Monitoring-System-3/vehicle/OVMS.V3 Thanks, Eddy

A recent change is causing OVMS spam

Some recent update is causing me to get OVMS Notifications, one a minute. I’m still running v3.0.6. Has there been a recent polling routine added to the server?This is super annoying.

Am I not updating in the correct order? #!/bin/sh set -x git fetch upstream git checkout master git submodule update --recursive git merge upstream/master git push Should the submodule update go last?
