You can reach me at the email address on this post. I have sent you another email from a Yahoo account. I received my cc of that email. So you should get your copy. Rick

No I actually didn't get it. Can you post an email address and I'll try sending a mail to you? Or, check the spelling of mine. It's just a regular Yahoo mail account, so I'm not sure what's going on. D

there is a open source embedded board based on PowerPC CPU available at www.openrb.com which could fit your needs. As this is open source OS based board you will be able to perform any changes you want in the code. Technical details * PowerPC processor: 266 or 333 MHz clock frequency * 1 or 2 ESD protected Ethernet ports * miniPCI sockets for 802.11 wireless cards and other expansion * 32-512 MB SDRAM, 64 bit wide for high memory bandwidth * 8 MB NOR FLASH for system BIOS and programs * True IDE CompactFlash (CF) for custom OS and applications like databases, FTP, emails, logs, proxy * 7 to 36 V DC supply through DC jack or Pover Over Ethernet * 2 RS232 serials ports (1 DB9 male socket), RS485 interface header * JTAG interface * Hardware and software watchdog timers * LM75 thermal monitor * GPIO header * USB 2.0 host * I2C bus header (can be used for front panel interface) * 2 LEDs and 1 pushbutton switch, freely programmable * Extender connector for optional Zigbee, HSDPA, GPRS, GPS, sensors and other modules * Board size: 115 mm x 97 mm * CE certified * Operating systems ported: OpenWRT, FlashSYS with revolutionary AJAX GUI, OpenEmbedded, ECos RTOS * OpenRB consumes less than 4W of power and is fully ROHS compliant Edgars

I sent another email a couple of hours ago. Did you receive that? Rick

Rick - I do check it. Please try again. I didn't receive an email. It's deanvesuvio [a*t] yahoo {[dot]} com

I sent you an email to the address shown here. Do you check your yahoo.com email account? Rick

I appreciate that. I'm a software engineer by trade, so I expect to be able to work around any such problems relatively easily. The thing I'm much much more concerned about is determining the right set of components for integrating the LPC213X with the XECom modem -- passives, plus whatever I need to make the UARTs on the LPC into RS232s that can communicate with the modem and a computer input. Does anyone out there have the expertise and the willingness to help with this? I'm assuming it would be a couple hours of time, and I'd be happy to pay a reasonable rate.

Also get the LPC213x Errata, at http://www.nxp.com/acrobat_download/erratasheets/ES_LPC2138_1.pdf because the LPC MAM (Memory Accelerator Module) has bugs that you must work around by configuring the MAM in a particular way. Or make sure to get new chips with these bugs corrected. -- Niklas Holsti Tidorum Ltd niklas holsti tidorum fi . @ .
