SandpointX3/Altimus with MPC7410/7445 (G4) and MPC107

= Motorola Sandpoint X3, a bit about the ppc reference platform = The Sandpoint is a reference platform designed by Motorola to help people develop hardware and software around various PowerPC processors. The basic system is an ATX form-factor motherboard with standard PC devices (IDE, floppy, serial, parallel), 4 PCI slots, and a mezzanine slot to which several different processor modules may be attached.

The Sandpoint evaluation system demonstrates the capabilities of Freescale PowerPC™ processors and the Tundra Tsi107™ PowerPC Host Bridge. The Sandpoint Evaluation System is the ideal platform for software development and debug, as well as for hardware development.

The Sandpoint evaluation system provides an example that can be used in designing other systems based on implementations of the PowerPC instruction set architecture, and a platform for developing and debugging software for these processors and associated bridge chips.

The motherboard inside the Sandpoint evaluation system is an ATX form factor with PCI Mezzanine (PMC) connectors that accepts a processor module. The processor module options are listed below. Links to the processor module web pages can be found under Evaluation/Development Boards and Systems on this page.

Sandpoint II Evaluation System
The Sandpoint II Evaluation System demonstrates the capabilities of the PowerPC® processors and the MPC107 PCI Bridge/Integrated Memory Controller, and is the ideal platform for software development and debug, as well as for hardware development.

The Sandpoint Evaluation System allows system designers to take months off their system design cycle by providing a complete PowerPC system that hardware and software development teams can both begin working on immediately. This eliminates the need to wait until the hardware team gets a board running to start application software development.

Sandpoint can be used as the starting point or a baseline design to help determine the best system design for a new product. It allows performance testing and evaluation of a number of PowerPC processors running at various speeds and configurations.

Sandpoint is housed in an ATX mini-tower case. The Sandpoint motherboard is an ATX form factor with a PCI Mezzanine Card (PMC) connector for the PowerPC processor. The Sandpoint PPCEVAL-SP2-750 processor is a MPC750/107 PMC module with 1 MB L2 cache. The PMC includes 32-MB of SDRAM already installed. Debug monitor software, DINK32, is also provided with the system.

Up to four PCI slot-based devices are supported. Two of these PCI slots are 5 volts and 32-bit. The other two PCI slots are 3.3 volts and 64-bit. The super I/O chip provides two standard 16650 compatible serial ports, an IEEE 1284 parallel port, a floppy disk port, two IDE ports, and PS/2 mouse and keyboard connectors.

DINK32
DINK32 was developed as an internal Motorola PowerPC tool to help debug silicon as well as code. It runs on a variety of boards including the Yellowknife, Sandpoint, Excimer and Maximer. DINK32 has the full complement of commands. DINK32 supports all of the currently available PowerPC microprocessors including the 603, 603e, 604 family, the integrated processor, 8200 the 8240, the 7xx family and the 7400. DINK32 is a great source for example code when initializing the MPC105, MPC106, MPC107 memory controllers/bridge chips. DINK32 source code also includes sample code for the MPC8240 subsystems, DMA, EPIC, I2C, and I2O.

memory issue
DINK32 (v13.1, too) initializes the wrong amount which will cause a kernel panic if you rely on the getting the amount of memory from how the memory ctlr regs are set up.

In the interim, you could write 'correct' values using the

dm i2c -a 50 0-7f'

0x80,0x08,0x04,0x0c,0x09,0x02,0x40,0x00, 0x01,0x75,0x54,0x00,0x80,0x10,0x00,0x01, 0x8f,0x04,0x06,0x01,0x01,0x00,0x0e,0xa0, 0x60,0x00,0x00,0x14,0x0f,0x14,0x2d,0x10, 0x15,0x08,0x15,0x08,0x00,0x00,0x00,0x00, 0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00, 0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00, 0x00,0x00,0x00,0x00,0x00,0x00,0x02,0x97, 0x7f,0x98,0x00,0x00,0x00,0x00,0x00,0x00, 0x46,0x4d,0x34,0x20,0x36,0x34,0x53,0x30, 0x36,0x34,0x43,0x33,0x2f,0x31,0x32,0x38, 0x00,0x00,0x00,0x00,0x00,0x01,0x1e,0x1f

setting? dunno, what google says about the similar SandpointX3/8240 board
Dunno about the 74** cpu module, but something specific is required to be configured in order to correctly initialize the dram (that fixes kernel panics).

Ok, there is no specific info about 7400,7410,7445, there is no uboot port, but i found uBoot installed in the flash memory of the CPU card of "Sandpoint 8240 X3 board", with the following DIP switch settings:

The followind detailed description of installation and initial steps with U-Boot and QNX was provided by Jim Sandoz sandoz@lucent.com

what doc says about setting for similar cpu module 745*
claiming success about "sandpointX3/MPC745*" with kernel tested at 1Ghz 100Mhz Memory

freescale was suggesting the following
 * AN2660, sandpoint-memory-consideration
 * AN2578, sandpoint-kernel-booting

SW1=01.11.11.10 SW2=10.10.10.00 SW3=10.00.10.01

0 means switch set to ON 1 means switch set to OFF other combination may not uncompress (bZimage??)

also she suggests the following on DINK13.1 on sandpointX3/ppc7445:

it's necessary to configure the I2c on the PMC for a single bank 128Mb memory.

To do this:

downloading using the net, DINK32.v13

 * instead of using the serial support still (DINK32 r13.0.0 and newer support 115200 baud)
 * you can use the ethernet card support, so loading a kernel will go much less painful

To download via the network, DINK uses fixed IP address and Realtek8139 NIC. The steps are:


 * do "ppr" verify NIC card has been identified vendor/device ID as 10EC/8139
 * do "env IO=COM1:9600 at 100, Then "reset"
 * do "ni -i " to set up your network parameters
 * set up you tftp server at host side
 * the download command is "dl -nw -b -o800000 -fzImage.sandpoint"
 * "go 810000"

For example:

DINK32[MPC7457] {1} >>ni NETWORK INFORMATION PCI CARD Type 8139/10EC on slot 16

SETTINGS SERVER(TFTP) : 192.168. 1. 1         GATEWAY      : 192.168. 1. 1         NETMASK      : 255.255.255. 0        DHCP         : 192.168. 1. 1         CLIENT(DINK) : 192.168. 1. 7

DHCP: Disabled SESSION TIMEOUT: Never

You can change IP addr, image name, to fit your setup, and as far as differences in the X2 vs. X3, yes there are important differences.

you can not ping
You cannot 'ping' DINK as the stack is not persistent. It is only usable when networking tasks are being performed. You might be able to ping it while doing a tftp, but I wouldn't count on it.

Use a pretty kernel if you want ping working.

uboot/ppcboot
is it supported about sandpoint ?

This is an actively developed ROM monitor and Linux boot loader ideal for custom boards, derived from 8xxROM and FADSROM. It includes support for BOOTP, RARP and TFTP image downloading and booting.

[]

PPCForth
PPCForth is a minimalist version of the FORTH language (for the PowerPC [tm]) which may be used as a test environment for boards, a bootloader, or even (shudder) a developement environment. I use it to boot my 403GCX board as well as loading C programs and other experiments. FORTH is particularly well suited for interactive testing as it is interpreted and as such may be extended on-the-fly. PPCForth is also rather small, weighing in at under 30K of code for everything, and under 10K for a bare-bones bootloader.

Currently PPCForth has only been ported to 403-based boards, but I am looking at supporting the 8xx series as well, as soon as I can get some actual hardware to try it on (donations anyone?).

Could you be more specific as to what is missing?

I don't know about the 74xx support in PPCBoot, but PPCBoot sets up the 107 in a MCP8245 on a Sandpoint X3 well-enough to boot linux. PPCboot does not, however, configure more than one 'bank' on the SO-DIMM socket, and does not (currently) read the SPDs, if only for the lack of proper I2C support (at least for the 824x).

YMMV.

My question is how have_of got set:

arch/ppc/mm/init.c:       if (!have_of) FREESEC(openfirmware);

Otherwise...

On the whole "'reset/reboot' the system" thread, I'm interested in similar solutions for the 824x, since I'm having highly similar problems on reboot. :-)

Interestingly, the 'gorom' solution works fine for me, as long as my root filesystem is not jffs2, then only if / is mounted 'rw'.

romfs, cramfs, nfs, or jffs2 (read-only) all reboot just fine.

On the DINK32 12.2 side it blindly sets some parts up for 64mb total regardless of the ammount of memory. I think there's other things as well, but Mark Greer would know better..

For DINK32 12.3 the first problem I've hit is that I can't seem to convince it to setup the SPD bits on the memory for the 64mb total that seems to be on the board, only 128mb. Using DINK32 12.2 and 12.3 to try and get all of that done 'correctly' still had things blowing up when I tried to use 64mb. But I've been busy tracking down other issues at the moment..

On !CONFIG_ALL_PPC, we have: In include/asm-ppc/processor.h, or so. And the compiler happily optimizes things in/out with this.
 * 1) define have_of 0

I should have been more explicit.

in include/asm-ppc/processor.h, I'd found:


 * 1) define have_of (_machine == _MACH_chrp || _machine == _MACH_Pmac)

A sandpoint (esp with Dink) is neither CHRP or PMAC, so the call to FREESEC(openfirmware) shouldn't have occurred.

Thanks for the memory jog :)

Up near the top, we have: ... int _machine; ...
 * 1) ifdef CONFIG_ALL_PPC
 * 1) else
 * 2) define _machine 0
 * 3) endif

So have_of becomes: (0 == 0x4 || 0 == 0x2)

It's !have_of, so we really did want to free the __openfirmware stuff.

I dunno guys, I think the compiler usually optimizes that all away and you should never see "openfirmware". I don't recall ever seeing it print out. I think something fishy is going on...

NetBSD
Currently, NetBSD/sandpoint requires the use of Motorola's DINK32 ROM to load over a serial port. This means that there is no way to boot from a local disk or PCI device.

Unsupported devices

Supported boot devices
Currently, the only way to boot the system is with the DINK32 ROM monitor's serial download or a JTAG device.

Installing

 * Booting the installer
 * Once the kernel is downloaded (s-rec ascii or binary), type "go 90000" to start the kernel.

Example of a normal boot

DINK32 currently only supports loading images through the S-record download command ("dl"). To speed up the process, the baud rate should generally be set to 38.400 baud

DINK32>> sb -k 38400 DINK32>> dl -k 38400 -o 90000

In addition, DINK32 supports a binary download feature which is about 150% faster again. To use this facility, srectobin could translate s-record to binary.

DINK32>> dl -k -b -o 90000

Of course, a lot of the information in this example depends on your model and what your boot method is, but we'll include this anyways just so you get an idea of what to expect (user-typed commands are in bold).

DINK32>> go 90000 [ XXX - insert boot w/ installer on ramdisk instead of this example ]
