Sc12 ipc@chip

This is a page about the boards SA007 brought to eth0:winter 2k12.

Specs

• Beck IPC@Chip SC12
• AMD 80186 @ 20Mhz
• 512kb ram
• 512kb flash
• 10mbit ethernet
• rs232+rs422 (via max488)
• File:SCHEMA.pdf
• File:Startup.pdf
• File:Controller datasheet.pdf

OUI vs Serial#

• OUI 00:30:56 'Beck IPC GmbH'
• MacAddr format: 00:30:56:fx:xx:xx, the xxx is (24 bit) serial number, written as 5 characters (hex).

Example:

A:\>ver
...cut...
Target=SC12 Serialnumber=xxxxx
...cut...
A:\>

Interrupt 0xA0 service 0x00: Get serial number.
http://isa.umh.es/temas/micros/doc/sc12/doc/biosints.htm#0xA00x00
Interrupt 0xA0 service 0x17: Get MAC address of the Ethernet interface
http://isa.umh.es/temas/micros/doc/sc12/doc/biosints.htm#Interrupt_0xA0_function_0x17__Get_MAC_address_of_the_Ethernet_interface

Memory map says: 0400h - 04FFh for MAC Address. Possible to change MAC addr (plz check later)? I guess that 'on boot, the default mac == serial'. And that we could configure it via program at boot?

• Pin17 @ SC12 = Link Led (connected to red led)

How to avoid periodic resets

• Disable tcp2con.exe in autoexec.bat

It looks like tcp2con.exe performs a device reset after 120 sec.

Note: Please remove this, before flashing new firmware to device! Maybe this reboot will kill a flash over ethernet? As long the bootloader works, you can flash it over serial again. But still, it's quite risky.

CGI HTTP

Default tools available:

• http://1.2.3.4/ChipCfg
• http://1.2.3.4/TCP2COM (reverse engineer, or write our own software)

Debugging

Hardware

"If it fails, the @CHIP prints the error message "RAM ERROR" on the COM port (using 19200 Baud and 8N1, regardless the entry in the CHIP.INI)."

Software

Use TRACE.EXE (seen in manual, link page here!) or maybe use the remote SYSLOG daemon ( http://www.lourensrozema.nl/ax/download/syslog_src.zip is ASM! untested..)
