MT3360-CE60-W1350-7444 2DIN / igo memory issues

Postby gwaitsi » Wed Aug 22, 2018 5:29 am

I have two different Chinese 2DIN HUs both with MT3360-CE60-W1350-7444 but slightly different dates for the firmware and a slightly different different button layout but the rest remains the same. One has inbuilt cam decoder, other uses an external plugin.

CPU is ARM1176JZF-S mt33xx and whos as 150Mb available program memory. without igo running approx 53m is used
NKV A10.2.0 2017.08.15 10.22 is the latest version firmware

Both units exhibit the same problems. If no iGo is used the unit is stable
- rear camera works without resetting unit
- surround sound enable
- music/videos from sd card play continuously

If igo primo 9.13.405512 is started automatically, unit is highly unstable.
if started manually;

- only the first song or current song plays till end on the sd card, then the unit either resets,
or doesn't continue until you switch to radio, and then back to repeat the problem (also true for USB and VMCD
- reversing after a few seconds causes the unit to reset (not 100% depends on run time) - the problem becomes notably worse when wifi tmc is used then is 100%
- turning off the surround sound, relieves many of the above problems.

It seems clear this is memory related. playing with the control panel program/ram allocation seems to make a different + and - but the settings are not retained.
I have tried to turn-off 3D and stripped all voices / maps /etc i don't need.

Any WinCE experts can provide some advice.

I have also made a number of other observations re memory usage.
If igo is running in the background without navigating, sd will run in the foreground without problems.
if igo is running in the background with navigating, sd will run in the foreground with a few songs before stopping
if igo is running in the background with navigating and wifi/tmc connected, sd will not run in the foreground.

for anyone else who may have found this, i have managed to get some stability into the unit.
- I have removed all the European countries i don't typically travel to i.e. russia is fairly large. inc languages, pois, etc.
- I replaced my mp4 audio with mp3, which had the side benefit of recognising the ID3 tags (doesn't seem to support mp4 tags)
- made a table of licences and what they enabled and stripped out all the duplicate/unnecessary ones

seems to have solved the above problems, however i am left with
- google services can't find server
- best of all....opera browser comes with malware proxy installed.
checked on two different brands with the same MT3360-CE
-W1350-7444 and they both try to connect to 111.11.6.75:1080 when trying to use opera.
