STM32F4DISCOVERY BOARD

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.
