Thread: Nanocom Evolution SD Card not reading

Hiya All.

Sorry it has been a few days more than expected before i have some news on this.

Some may remember that in our first BBS release we were having some owners managing to somehow corrupt their Firmware drive contents which resulted in us making this read only and totally protected against any changing ogf its contents except for during an update.

Naturally, to now have the remapping function be able to pre copy a map to that memory was sort of counter to that protection.

We have therefore pretty much been fighting ourselves in this respect and as such implimenting this has taken longer than initally expected.

It is now however finally done and the new methology of moving the data to be written to the TD5 ECU into the Firmware memory prior to attempting to write it into the ECU has had quite a few previously unforseen benefits that make the process much smoother etc.

We are currently performing some in house testing prior to releasing this for Beta testing, but already things are looking much improved.

Hi Colin,

That is fantastic news. I'm looking forward to giving it a try.

cheers

Colin quick quick I have an urge to do some mapping

Cheers Guys

We really appreciate the support and understanding on this, as i am sure you also appreciate being directly informed of the situation and nitty gritty Detail.

Our in house testing went well and showed that there are indeed significant benefits of this new methodology and we are now almost totally matching the Nanocom one's programming in every aspect, and so have indeed removed the negative effects that are added by using the SD Card as the data source during programming, that is unique to the Evolution and seems to be the core problem, but our in house testing did throw up a couple of problems that needed addressing, interestingly also the ability to improve things even more.

But then that is why we do in house testing first

These changes have now been made and the new software changes will soon be re tested in house and as long as nothing major is flagged up wil will release this for Beta Testing.

I appreciate it is always agonising to have to wait for something like this, but it is better to be waiting for a bus you know is coming rather than one that may never come.

Colin thank you for your thorough testing! That way the bus that we get on doesn't break down after we start the journey.

Sorry to not get back to you all sooner on this, it's been a really hectic time recently, as i have so many things on the go at once and on top of that i have been having to deal with the most ridiculous and abusive customer we have possibly ever encountered.

Our last in house testing of this new TD5 map writing methodology was actually pretty stunning.
We worked an already Iffy SD card right to the limit, filling it completely with files, deleting them, re adding loads and then adding a map file. We proved that with the existing process it would always fail, but with the new process it had a 95% sucess rate.

But very occasionally we were seeing that the system would freeze in the initial security access negotiation prior to even attempting an upload.

While a fail at this point would never cause a non working ECU situation anyway, like a mid point write would, call us greedy, but we have already achieved so much and if at all possible, we really do want that missing 5% reliability

And therin lies the problem. It's really hard and very time consuming to track down a problem that only ever happens one time in 20 or 30.

We do however think we have now sussed this and with time going by, are now preparing a Beta release for others to test which we hope to have ready before the weekend.

In fainess it is a bit of an untested gamble, but since it is only for the last 5% anyway we feel it worth beta releasing at this point.

Warmest Regards

Colin

Any updates please?

Yeah updates?

I am about to write a map file and want to make sure I use the best process possible.
