[Ovmsdev] ota questions

[Michael Balzer]

Working on the OTA web UI.

Some questions:

a) Flashing and changing the boot partition outputs some irritating overflow and "??" log messages:

OVMS > ota flash vfs /sd/ovms3.done
Current running partition is: ota_0
Target partition is: ota_1
Source image is 1480592 bytes in size
Preparing flash partition...
Flashing image partition...
Setting boot partition...
OTA flash was successful
  Flashed 1480592 bytes from /sd/ovms3.done
  Next boot will be from 'ota_1'

Can these safely be ignored? The flashed partitions seem to work correctly.


b) How do you get back to the factory partition if something went so wrong you can't use the "ota" command?

I would have expected "make flash" to reset the boot partition to "factory", as all flashes are only done there, but it doesn't.

So if you're on another partition with a broken firmware, how do you recover? Is there a way to set the boot partition using esptool.py?


c) ota flash http still gives me a DNS lookup error on any other host than api.openvehicles.com and fails to download from api.openvehicles.com, regardless of
the type of network (wifi/modem).

OVMS > ota flash http www.google.com/ovms3.bin
Current running partition is: factory
Target partition is: ota_0
Download firmware from www.google.com/ovms3.bin to ota_0
Error: Request failed
W (666891) net: DNS lookup on www.google.com failed err=200

OVMS > ota flash http api.openvehicles.com/test.bin
Current running partition is: factory
Target partition is: ota_0
Download firmware from api.openvehicles.com/test.bin to ota_0
[…dead, needs reset]

Is this a local problem of mine?

Michael
