Hi list,
Another quick post to share with you the progress on the ESP-IDFv5 + cmake endeavour:
ESP-IDF v5 version of OVMSv3 is now officially booting and seems to work fine (then again, I'm not doing any real-world testing for lack of time / car at the moment - it's here that you can help me) with a few caveats detailed in the PR or the README.md <https://github.com/llange/Open-Vehicle-Monitoring-System-3/blob/experimental-esp-idf-v5/README.md>.
The branch https://github.com/llange/Open-Vehicle-Monitoring-System-3/tree/experimental... is now ready for testing, sharing, studying, ...
I created a draft PR https://github.com/openvehicles/Open-Vehicle-Monitoring-System-3/pull/810 (just like for ESP-IDFv4), in order to show the diff and gather feedback. Not to be merged as-is.
I'll try to break it into smaller low-impact / easy-to-review PR's that could be merged as-is in current master (warning corrections, header definitions, xxprintf type impact, etc...), so that the big pieces could be more easily reviewed.
Please note that those branches / PRs are still Work-In-Progress, and
that I may certainly (and wrongly) push --force some changes as I
rebase, update or split the big PR into smaller, easy to study PRs. I'll
try not to but can't promise :-)
So if you checkout the branch, please be warned and know your git
commands to either reset or rebase your working copy...
Next on my list are, in no particular order:
- Have a few patches/bugs fixed in upstream wolfSSL (in progress) in order to enable
- Check to see if we could upgrade mongoose (not absolutely necessary because it works / compile OK with a small patch)
- Fix the remaining warnings o And change the ADC implementation that is deprecated now o deprecation of esp_vfs_fat_spiflash_mount / esp_vfs_fat_spiflash_unmount
- Fix the WIP WIP WIP commits
- Resume work on https://github.com/openvehicles/Open-Vehicle-Monitoring-System-3/issues/752
Boot time warnings to study and check if OK:
- W (1091) esp_psram: Virtual address not enough for PSRAM, map as much as we can. 4MB is mapped
- W (2132) ADC: legacy driver is deprecated, please migrate to
esp_adc/adc_oneshot.h(<- this one is easy to understand...)
Additional instructions:
When first building, your sdkconfig will be converted as some config options did change betwen ESP-IDF v3.x and v5.x.
Run menuconfig and :
- *Select FREERTOS_ENABLE_BACKWARD_COMPATIBILITY*(=y) "configENABLE_BACKWARD_COMPATIBILITY"
- *Unselect MG_ENABLE_SSL*(=n) "Enable MONGOOSE SSL/TLS support"
If any of you with some free time could be nice enough to try to reproduce such a build and share the experience here. Let me know how the instructions could be updated and what issues you are facing.
Best regards,

I may try this on my spare board as a start! (The Aux 12v switch didn't work... But otherwise it's mostly OK)

Progress looks good on this. Thanks for stepping up to try to tackle it. Pain points for me with our current approach are: 1. RAM usage (in particular IRAM) 2. IDF bugs that may be improved in newer versions 3. Support for newer hardware (including ESP32-S3) #3 would give us a welcome 12 more GPIOs with minimal hardware changes, but possibly worse RAM situation (520KB->512KB, see #1). My preference would be v5 IDF (for the newer hardware support). I think it would be fine to have this as a new branch. Not particularly important to make it work in the master one.
