I think there is a problem with the simcom support. The following trace 
at the bottom of this mail happens on startup and it reboots before 
doing it again in a loop. I haven't  startup tasks. I've got the 
hologram simcard in it but haven't registered it or anything like that, 
so maybe an error is being reported that isn't being handled. I turned 
off the simcom support in make menuconfig and it's stable.

The vfs things don't work:

OVMS > vfs mkdir /store/scripts
Error: Could not create VFS directory

It also used to store my config across power cycles but it doesn't do 
that anymore.

Is this relevant:

I (1132) ovms_main: Mounting CONFIG...
E (1132) vfs_fat_spiflash: Failed to find FATFS partition (type='data', 
subtype='fat', partition_label='store'). Check the partition table.
Initialising OVMS CONFIG within STORE

I appear to be using the ./vehicle/OVMS.V3/partitions.csv partition 
table, does /store need formatting? I see there is autoformat code in 
the sdcard paths, but not in the internal storage?

Simcom reboot loop referred to above:
