Page 5: Chapter 1 Introduction
The MOXA UC-7110 Series of RISC-based Communication Platforms features two RS-232/422/485 serial ports, and dual 10/100 Mbps Ethernet ports, making these products ideal for embedded OS applications. This chapter covers the following topics: Overview Package Checklist Product Features Product Specifications... -
Page 6: Overview
This means that software written for desktop PCs is easily ported to UC-7110 by using a GNU cross complier, so that you will not need to spend time modifying existing software code. The Operating System, device drivers, and your own software can all be stored in UC-7110’s Flash memory. -

UC-7110 Series User’s Manual Although JFFS2 is a journaling file system, this does not preclude the loss of data. The file system will remain in a consistent state across power failures, and will always be mountable. However, if the board is powered down during a write, then the incomplete write will be rolled back on the next boot. - Page 32 UC-7110 Series User’s Manual busybox backupfs downramdisk upramdisk ttyS0 tty3 tty2 tty1 tty0 rom1 rom0 ptypf ptype ptypd ptypc ptypb ptypa ptyp9 ptyp8 ptyp7 ptyp6 ptyp5 ptyp4 ptyp3 ptyp2 ptyp1 ptyp0 ram1 ram0 null kmem cua0 console tty Software Package...

A rule (such as a jump to a user-defined chain in the same table) is called a “target.” UC-7110 supports 3 types of IPTABLES table: Filter tables, NAT tables, and Mangle tables: A. Filter Table—includes three chains:... - Page 36 UC-7110 Series User’s Manual OUTPUT chain—produces local packets sub-tables Source NAT (SNAT)—changes the first source packet IP address Destination NAT (DNAT)—changes the first destination packet IP address MASQUERADE—a special form for SNAT. If one host can connect to the Internet, then other computers that connect to this host can connect to the Internet when the computer does not have an actual IP address.
- Page 37 Filter Table INPUT Chain Local Process Mangle Table OUTPUT Chain NAT Table OUTPUT Chain Filter Table OUTPUT Chain UC-7110 supports the following sub-modules. Be sure to use the module that matches your application. ip_conntrack ip_conntrack_ftp ipt_conntrack_irc ip_nat_ftp ip_nat_irc ip_nat_snmp_basic ip_queue ipt_LOG NOTE UC-7110 does NOT support IPV6 and ipchains.

-
Page 39: Nat
IP addresses used on another network. One network is designated the inside network and the other is the outside network. Typically, UC-7110 connects several devices on a network and maps local inside network addresses to one or more global outside IP addresses, and un-maps the global IP addresses on incoming packets back into local IP addresses. -

Page 59: Appendix C Faq For Uc-7110
What stack size can I use when creating a user application? Answer 4 First note that UC-7110 is not an MMU processor. The OS is uClinux, so you must transfer your application from ELF to FLAT format. The transfer utility (on the PC) assigns a stack size of 0x1000 by default. - Page 60 5% to 10% when you copy the program into JFFS2 Flash. FAQ 6 Since UC-7110’s tool chain currently does not support GDB server, how do I disable a function by using the Makefile example to generate the gdb file? Answer 6 Edit the file /usr/local/arm-elf/bin/ld on the PC Linux platform.
