RS232 deployment works with Netduino Plus but not Netduino

Hey Chris,

This worked like a champ! (I'm able to deploy now to the Netduino over RS232. Had completely forgotten about the need to use MFDeploy to alter the deployment settings.)

Many thanks for the quick response!!

Hello,

I've installed the 4.1.1.0 beta firmware on a Netduino board and tested with a simple app to ensure that it's working. (Blinking LED...)

Next step was to add an RS232 shield and test HID firmware that's already running on a Netduino Plus. I attached the shield and used a USB/RS232 cable [with FTDI chipset] to deploy the firmware. However, the deploy fails and times out. The error I see is: "Unable to communicate with device - Serial: COM4".

Just to verify that there wasn't an issue with the shield or cable, I reattached the same shield to a Netduino Plus and deployed. This worked without any issue.

Has anyone else observed similar issues with RS232 shields and the Netduino?

Thanks!

Hi donnmo, By default, Netduino uses the USB port for debug/deploy. If you want to switch to COM1 (pins D0/D1) you'll want to use the following tool: http://forums.netdui...b-and-com1com2/ Does that help? Chris

Hello!

Just for my piece of mind, how come you're using a release, Beta or otherwise, that's older then the currently available ones for your devices?

I'm building HID devices (that communicate directly with Windows 8.1 using the inbox drivers that ship with the OS). It's my understanding that the 4.1.1.0 beta versions of the firmware are the only versions that support the creation of these devices.

If I'm wrong, and the more recent firmware versions support the creation of HID devices, it'd be great news. But, if not, the earlier versions are working well.

Thanks!
