EdgeTX
Issue with EM handling in main
Is there an existing issue for this problem?
- [X] I have searched the existing issues
What part of EdgeTX is the focus of this bug?
Transmitter firmware
Current Behavior
After EM happens, SD is mounted, sound is available, I guess LUA possibly too
Expected Behavior
In EM reboot mode, SD must stay unmounted, to prevent entering a EM loop sequence
Steps To Reproduce
Trigger EM on a debug build
Version
Nightly (Please give date/commit below)
Transmitter
Other (Please specify below)
Operating System (OS)
No response
OS Version

Anything else?
Found this testing future hardware, but the issue is not hardware related. I have seen it in BW, I have not checked colorlcd (nor have I tested 2.10). I will not be able to work on this for at least 5 or 6 weeks
Are you building without RTC_BACKUP_RAM set?
Looking at the code the behaviour you describe would only happen if RTC_BACKUP_RAM is not defined.
It should be; but looking at the code this is the only reason I can see why the SD would be mounted.
It would appear the RTC_BACKUP_RAM is not defined for B&W radios. It looks the same in OpenTX.
Since there is no backup what else can EM do; but load the model settings from the SD card?
Yeah but OTX had models in eeprom. The issue is you can run into boot loops if the source of the EM is sd card related. Need to assess what we can do, maybe limit sd access to bare minimum.
Also, many new BW are using F4, need to check if the rtc register are available on those
I have successfully run RTC_BACKUP_RAM based EM on a RM Boxer, will do a PR for BW F4 when I'm physically capable
