1  Hardware and U-Boot firmware / Hardware / Re: USB Serial Support on: February 01, 2010, 08:46:13 AM

I'm going to use an Arduino for data acquisition and control and would like to be able to load new firmware from the embedded system.  I am unfamiliar with the difference between a pty and a tty, will a pty give me the ability to reset the Arduino from the embeeded system and load new firmware?

I really like your obdgpslogger program, it looks very interesting and I may have to try it after I finish this project.

Thank you for your help and I appreciate the input.

I guess I'll be rebuilding my kernel.  Luckily this isn't the first time.  Used to work for an embeded Linux company.

SD for storage is still on the table.

About, the embedded databases.  Which databases are available and free (beer and speech)?  I'll admit I haven't done a google search yet, but I'd like your input as to which ones work well and can be used with the PHP and C languages.

We have not decided if the DB will be local (SD) or remote (don't want to deal with sysadmins to much).  However, we know we want to use some network storage for the export files so we may have the ability to host the data base on NFS/SMB.  Performance wise we should be fine as the readings only come in every 5 min or so.

My name is Spenser, I am an ECE undergrad at Baylor and my group is trying to make a data acquisition system for the solar power system on the roof of the engineering building.  We are thinking of using a SheevaPlug as the heart of the system.  Its main goal would be to take in serial data and store it in a database.  Furthermore, we would like it to host a PHP based website that will let us visualize the data.  My questions are as follows.

1.) Does this version of Linux support usb FTDI devices (USB to Serial)?  I know that Ubuntu on my laptop supports it but will the stock kernel on this device support them.
2.) I have heard problems about SD cards dying out very quickly in SheevaPlugs.  Is it wise to store important data on SD card?
