For more interesting projects done by Flameman, be sure to check out his project index

RouterBoard-rb532-Flameman

Note

i'm developing for this board, the wiki page will be improved soon

feel free to contact me (see the contact below)

Introduction

The Target-goal of this page is

  • install gentoo-mipsel into microdrive
  • make the board able to boot from it
  • describe how to build a jtag cable (to debug and recover from "Brickage")
  • describe something useful with you can do with the board
  • describe other Operating Systems avalaible for the board


logical steps about installing gentoo

  • add the JTAG connector at J10 (you could skip it, it is suggested)
  • build the JTAG cable (you could skip it, it is suggested))
  • study the bootloader
  • make partitions on the microdrive
  • populate them
  • set the bootloader environment to boot from the microdrive

People you could contact if you need help

  • flameman, i'm currently use this board for a project, email
    • msn daredevil-coder@hotmail.it
    • email flamemaniii@gmail.com
    • irc.nick flameman (channel #edev, #gentoo-ppc)
  • you ... if you want ;-)

About the board

rb532 is a shortened name for the routerboard

you could get your board from http://routerboard.com/rb500.html

see the nearest reseller of the area where you live mind a brand new boards costs 140Euro + shipping and VAT cheaper way requires (fortune and) ebay searched for

Overview

The board consists of:

  • CPU IDT MIPS 79RC32434, a solid & smart implementation of the mipsel little endian MIPS 32 4Kcore CPU architecture, running at 400mhz (adjustable from 200 to 400MHz; 400MHz default and recommended)
  • RAM soldered 64MB DDR onboard memory chip
  • LAN On-chip 3 ethernet: One IDT Korina 10/100 Mbit/s Fast Ethernet port supporting Auto-MDI/X, Two VIA VT6105 10/100 Mbit/s Fast Ethernet ports supporting Auto-MDI/X.
  • UART One DB9 RS232C asynchronous serial port, speeds up to 230k, tested up to 115200bps
  • miniPCI Two MiniPCI Type IIIA/IIIB slots
  • CF support for IBM/Hitachi Microdrive (/dev/cfa)
  • ROM 1Mbit NAND flash where it is stored the bootloader
  • POWER IEEE802.3af Power over Ethernet: 12V or 48V DC, Power jack/header 6..22V or 25..56V DC jumper selectable. PoE does not support power over datalines
  • System PCB 14.0 cm x 14.0 cm
  • RTC the real time clock chip is missing
  • LED Power, 2 LED pairs for MiniPCI slots, 1 user LED
  • Watchdog IDT internal SoC hardware watchdog timer


NOTE: from the base configuration of 3 Ethernet ports and 2 MiniPCI slots (for wireless cards) it can be extended by using daughterboards for four more MiniPCI slots, or even up to a total of 15 interfaces (9 Ethernet ports and 6 MiniPCI slots). A wide range of accepted input power means that you can connect to almost any direct current power source you already have on site. It also can be powered through an Ethernet port using Power-over-Ethernet technology (802.3af) or passive non-standard PoE.

NOTE2: there is a daughterboard for the RB532. It is called RouterBOARD 564, and It attaches to the RB532 by means of special daughterboard connector and adds four more MiniPCI slots and six ethernet ports. You can not use more than two AR5414 chipset (e.g. R52) cards in RB/564. If you want to use three or four miniPCI cards in RB/564, you should use other chipset based ones for those extra slots, like CM9. For example, two R52 + two CM9 is OK, four CM9 is also OK, but not three or four R52.

Memory Locations

memory map of the board will be added as soon as possible


addr begin addr end area
... ?? ram, userspace
400000 ?? ram, userspace

Open questions


1) how/where is ram mapped ?

2) how/where is microdrive mapped ?

3) how/where is pci mapped ?

3) what is the bootstrap addr of the flash ?

2.6.22 vanilla+patch compiled on ppc-7410, minerva arc=mips-el, target=mips-1 gcc-4.1.2-glibc binutils-2.19 rocks, 6 days uptime hardly compiling, korina sometime stalls, VIA works
2.6.24 vanilla+patch compiled on ppc-7410, minerva arc=mips-el, target=mips-1 gcc-4.1.2-glibc binutils-2.19 korina is now working, VIA works (korina and VIA statically compiled)
2.6.30.6 vanilla+patch compiled on ppc-7410, minerva arc=mips-el, target=mips-1 gcc-4.1.2-glibc binutils-2.19 korina is working, VIA is not working, name eth0 inversion, korina is not eth0, korina and VIA statically compiled, the suggestion looks like compiling the via-rhine driver as module and load it after the korina, this may works for 2.6.30.6,2.6.30.5,2.6.30.1 also with rc6
