Hi!

what problem do you observe?

/Sergey

On a related note to this, has anyone been able to actually communicate with the board using Putty. I've scoured the net looking for anyone who has actually done stuff with the board using java me but nothing has turned up. From the "Getting started" instructions I was able to get to the point "Using the Java Logging Interface" however my Putty connection attempt would time out. Has anyone ran into this problem?

Have you been able to establish a PPP connection to the board? This is what described in Chapter 1. If yes, I would suggest you to look into ITM logging from the MCU. For example if you use Keil MDK please switch it to debug mode, open "View/Serial Windows/Debug (printf) Viewer". I would suggest you to use this logging instead of TCP one because of the problem with it. It's mentioned in Release Notes under "IP logger doesn't work" title.

Hello andrey_p,

Thank you for the reply. I believe I have established a PPP connection and I've started the tooling proxy as described. Skipping the section about "Using the Java Logging Interface" I went to "Using the Command-Line Interface".  From the "oracle>>" prompt I attempted to issue command "ams-list". However it returned with "<<ams-list, FAIL, device is not connected. I'm not quite sure what is going on.

It looks like there is some connectivity issue or java has not started for some reason. Could you please indeed try to use ITM logger and post here the log you see. That would help to find out what wrong. Also please try to ping the board "ping 192.168.125.1" - does it answer?

Regards,

Andrey

This is strange. When I went back to look at the "Getting Started" document it appears to be missing. Looking through Oracles website there is no mention of the STM32F4DISCOVERY anymore. Did Java ME 8 drop this platform?

Hello,

I think the description is still listed and the already updated the EA version for Raspberry to EA2 as you can read in the release notes. Oracle&amp;reg; Java ME Embedded Reference Platform Release Notes (Raspberry Pi) which is named "Release 8 EA 2" Beta Draft: 2014-02-05 now.

On the page: Java ME Embedded - Downloads | Oracle Technology Network | Oracle the STM32f4 version is still listed but the release notes are pointing into nowhere as the getting started guide. The binaries are still accessible for both platforms, but the STM32f4 version is still EA as the Raspi ones are EA2 already.

Any comments from Oracle on this?

Thanks,

Michael Kroll.

Hi Michael,

Looks like an incorrect page got pushed. We're checking it.

Thanks,

Hi Terrence,

the STM32f4 VM is still pointing to the version of September 2013, while the raspberry version is already updated in February 2014.

Will there be an update for the STM32f4 as well?

Cheers,

MIchael.

Hi Terrence,

the Links Oracle&amp;reg; Java ME Embedded Reference Platform Release Notes (STMicro Discovery) and Table of Contents are broken again.

Working on an update ?

Cheers,

Michael.

Michael,

I just tried it - works for me. Please refresh the page and try again.

Best,

Hi Terrence,

ok, got it now.

Since the releases are rather old now, when do you expect another EA or even beta version?

Cheers,

Michael.

Michael,

Stay tuned - there will be more information shortly.

Thanks,

Hello Terrence,

sorry to bother again regarding the STM32f4Discovery board support for JavaME8.

I can now find a new version of the JavaVM8 with "New support for Qualcomm IoE 6270T on Brew MP", but there is no mention of the STM32f4 Discovery board.

Has support for this platform dropped by Oracle or will support for the STM32f4 Discovery board added shortly again?

Cheers,

Michael.

Hi Michael,

Correct, the EA #2 release supports Windows, RasPi, and Qualcomm IoE. Cortex-M platforms remain very important, we plan to get back to updating the support for that platform in the near future.

Best,

Hi Terrence,

this are good news :-)

I wanted to come over to Embedded World to discuss the new platform in person with oracle representatives, maybe you, but cannot make it this year. So I'm exicited to see what you will come up with in the near future.

Thanks for letting me know,

MIchael.

Too bad you can't make it to EW. I will be there, so if anyone on this forum wants to come over an chat or check out the demos, please do: Embedded World hall 5, Oracle booth (271)

Best,

Hi Terrence,

Any idea when you guys will release support for the STM32F4 Discovery board?

Thanks

Roy

Hi Roy,

Due to Oracle policies I can't talk about specific releases before they have been publicly announced. I can say we are already working on one small Cortex-M platform and we're looking at several others from STM and other vendors.

Best,

Hi Terrence,

I fully understand. Can you at least give us an idea when we can expect any announcement regarding a Cortex-M related platform? Weeks/months? Apologies for being so pushy but I am developing a product based on the Cortex processor and am being squeezed for time regarding the programming language of choice. Being an experienced Java programmer and that this decision will have long term repercussions, it would be very nice to have some sort of indication regarding Java ME support for the ARM Cortex processor range. If I know the support isn't too far away I can start developing on my Raspberry Pi so long and then move it over to a Cortex board when support becomes available. If the support is still a year away I will be forced to look for another alternative.

Thanks for your understanding.

Regards

Roy

Roy,

Sure - I'd like to understand your project and use case better. Can you please contact me directly at terrence.barr /at/ oracle.com?

Thanks,
