Any time frame on fixing the RS232 version of the firmware?

[SteveS]

OK. I have upgraded the firmware to TTL successfully. However, I cannot deploy the transport selector, nor can I build it for 4.2 and deploy it. However, it reassures me somewhat that I haven't done anything with the mini to permanently destroy it. Also, I have deployed an app to it that uses the 12v serial connection successfully, so I'm almost there... Is there a prebuilt 4.2 transport selector anywhere I can download and deploy? SteveS

Hi SteveS,

Is there a prebuilt 4.2 transport selector anywhere I can download and deploy?

Here is the project source. If you switch it to NETMF 4.2, you should be able to deploy and run it on your Netduino Mini.

Please let us know how this works for you. We're making one other small change, and hope to have a revised RS232 firmware image shortly.

Hi Chris

Not exactly good news. I was able to build and deploy it, but it doesn't seem to run. I have Putty running on both a USB/TTL adaptor connected to Tx0/Rx0 and on COM1 connected to DTX0/DRX0, and nothing seems to be coming out of either port.

I am going to try 'hard-setting' the transport port using the code in the selector as a guide, to see if that works.
Unfortunately it's been a busy weekend, so I wasn't able to do this yet.

I tried setting the interface to Com1 and Com2, neither of which seem to make the RS232 port work as the transport, so I guess I will need to wait for the new firmware.

Hi SteveS, Thanks for testing this. It might be seeing the same core issue. We'll pull it in and try to fix both at the same time. Can you use TTL for deployment for the moment? Chris

Hi SteveS,

You're welcome. I've been a software developer for 30+ years, so I know how it is. Stuff happens.

Can you use TTL for deployment for the moment?

As it happens, yes - I'll be doing some work on an N, rather than a mini for the next phase of my project.

Chris, I'm having the same problem that Steve is having. Been struggling with this all day until I found this thread that explains what is going on. Our prototype units are running on the NetduinoPlus perfectly. We're ready to begin a production design using the Mini. Just wanted you to know that I'm waiting on this RS232 firmware update also. Any updates yet? Ron

[Chris Walker]

Hi Ron, We're currently looking at 19-Sep for a first update to the Netduino Mini firmware. We're syncing it was a PWM update for all Netduinos, so it needs a few days of lockdown and testing. I'll post as soon as it's ready. Chris

Just finished flashing my two Netduino Minis to the 4.2.0.1 RS-232 Firmware and it went off without a hitch. Thanks guys for getting this fix out so quickly.

[SteveS]

Great! After a somewhat tiresome day at the office yesterday (and Saturday isn't a good day for that anyway), I have had a fun 20 minutes reflashing my mini devices. I am very pleased to report that it all went smoothly, and I'm now planning on doing the same with my N/N+ boards to bring them up to the latest firmware. Many thanks, Chris. SteveS
