How to reproduce exatly the same ovms3.bin (3.2.002-151-g56116fe) build
by Bernd Geistert 09 Aug '19

Hi all, I would like to have a defined toolchain for building ovms3.bin, so that I can reproduce the same binary (for the same GIT #tag of course) from where I can start and later share own development. I have downloaded the "reference" ovms3.bin (3.2.002-151-g56116fe Thu Aug 1 16:04:20 UTC 2019 Automated build (markhk8), size = 2594192 bytes), but this is different to my own build in the mingw32 console using $ make clean $ make all Toolchain path: /opt/xtensa-esp32-elf/bin/xtensa-esp32-elf-gcc Toolchain version: crosstool-ng-1.22.0-80-g6c4433a5 Compiler version: 5.2.0 Python requirements from C:/msys32/home/.../esp/esp-idf/requirements.txt are satisfied [Python 3.7.3] App "ovms3" version: 3.2.002-151-g56116fe1 CC build/app_update/esp_app_desc.o AR build/app_update/libapp_update.a Build version is 3.2.002-151-g56116fe1 CXX build/main/ovms_version.o AR build/main/libmain.a Generating libapp_update.a.sections_info Generating libmain.a.sections_info Generating esp32.project.ld LD build/ovms3.elf $ ls -l build/ovms3.bin -rw-r--r-- 1 Matthias None 2592512 5. Aug 21:12 build/ovms3.bin At first, my ovms3.bin build was size 3036096, but I modified the make menuconfig default 'Compiler Optimization' from 'Default' to 'Release', the size inow similar to edge/ovms3.bin, but not the same. Maybe someone could tell about other important settings in "IoT Development Framework Configuration", maybe this could be the path to match exactly markhk8's setting for 'Automated build'? I described this also in https://www.openvehicles.com/node/2263 Regards Matthias

JTAG debugging
by Marko Juhanne 03 Aug '19

Hi, has anyone tried JTAG debugging with OVMS? Mainly interested in having settable breakpoints (a feature which doesn't seem to be possible with UART gdb stub in ESP32, but seems to work with ESP8266. See https://visualgdb.com/tutorials/esp8266/gdbstub/ ). There's no JTAG header on OVMS, but I'm willing to solder a JTAG connector directly to ESP32 pins. But those pins are already connected to the SD-card reader.. Is not having a sd-card in the slot enough, or does the initialization mess with the debugger connection, thus needing to disable the sd card module on firmware? Or do I have to desolder the reader? (last resort) Br, Marko
