HCU4 Configuration Details
Memory Bank 0 -- Flash chip
---------------------------
0xfff00000 - 0xffffffff
The flash chip is really only 512Kbytes, but the high address bit of
the 1Meg region is ignored, so the flash is replicated through the
region. Thus, this is consistent with a flash base address 0xfff80000.
The placement at the end is to be consistent with reset behavior,
where the processor itself initially uses this bus to load the branch
vector and start running.
On-Chip Memory
--------------
0xf4000000 - 0xf4000fff
The 405GPr includes a 4K on-chip memory that can be placed however
software chooses. I choose to place the memory at this address, to
keep it out of the cachable areas.
Internal Peripherals
--------------------
0xef600300 - 0xef6008ff
These are scattered various peripherals internal to the PPC405GPr
chip.
Chip-Select 2: Flash Memory
---------------------------
0x70000000
Chip-Select 3: CAN Interface
----------------------------
0x7800000
Chip-Select 4: IMC-bus standard
-------------------------------
Our IO-Bus (slow version)
Chip-Select 5: IMC-bus fast (inactive)
--------------------------------------
Our IO-Bus (fast, but not yet use)
Memory Bank 1 -- SDRAM
-------------------------------------
0x00000000 - 0x1ffffff # Default 32 MB

HCU5 configuration details and startup sequence
(C) Copyright 2007 Netstal Maschinen AG
Niklaus Giger (Niklaus.Giger@netstal.com)
TODO:
-----
- Fix error: Waiting for PHY auto negotiation to complete..... TIMEOUT !
- Does not occur if both EMAC are connected
- Fix RTS/CTS problem (HW?)
CONFIG_SERIAL_MULTI/CONFIG_SERIAL_SOFTWARE_FIFO hangs after
Switching to interrupt driven serial input mode
- Make vxWorks start from u-boot. Possible reasons
- Does vxWorks need an entry for the Machine Check interrupt like this
tlbentry( 0x40000000, SZ_256M, 0, 1, AC_R|AC_W|AC_X|SA_G|SA_I ) ?
Caveats:
--------
Errata CHIP_8: Incorrect Write to DDR SDRAM. (was not applied to sequoia.c)
see hcu5.c.
Memory Bank 0 -- Flash chip
---------------------------
0xfff00000 - 0xffffffff
The flash chip is really only 512Kbytes, but the high address bit of
the 1Meg region is ignored, so the flash is replicated through the
region. Thus, this is consistent with a flash base address 0xfff80000.
The placement at the end is to be consistent with reset behavior,
where the processor itself initially uses this bus to load the branch
vector and start running.
On-Chip Memory
--------------
0xe0010000- 0xe0013fff CFG_OCM_BASE
The 440EPx includes a 16K on-chip memory that can be placed however
software chooses.
Internal Peripherals
--------------------
0xef600300 - 0xef6008ff
These are scattered various peripherals internal to the PPC440EPX
chip.
Chip-Select 2: Flash Memory
---------------------------
Not used
Chip-Select 3: CAN Interface
----------------------------
0xc800000: 2 Intel 82527 CAN-Controller
Chip-Select 4: IMC-bus standard
-------------------------------
0xcc00000: Netstal specific IO-Bus
Chip-Select 5: IMC-bus fast (inactive)
--------------------------------------
0xce00000: Netstal specific IO-Bus (fast, but not yet used)
Memory Bank 1 -- DDR2
-------------------------------------
0x00000000 - 0xfffffff # Default 256 MB
PCI ??
USB ??
Only USB_STORAGE is enabled to load vxWorks
from a memory stick.
System-LEDs ??? (Analog zu HCU4 ???)
Startup sequence
----------------
(cpu/ppc4xx/resetvec.S)
depending on configs option
call _start_440 _start_pci oder _start
(cpu/ppc4xx/start.S)
_start_440:
initialize register like
CCR0
debug
setup interrupt vectors
configure cache regions
clear and setup TLB
enable internal RAM
jump start_ram
which in turn will jump to start
_start:
Clear and set up some registers.
Debug setup
Setup the internal SRAM
Setup the stack in internal SRAM
setup stack pointer (r1)
setup GOT
call cpu_init_f /* run low-level CPU init code (from Flash) */
call cpu_init_f
board_init_f: (lib_ppc\board.c)
init_sequence defines a list of function to be called
board_early_init_f: (board/netstal/hcu5/hcu5.c)
We are using Bootstrap-Option A
if CPR0_ICFG_RLI_MASK == 0 then set some registers and reboot
Setup the GPIO pins
Setup the interrupt controller polarities, triggers, etc.
Ethernet, PCI, USB enable
setup BOOT FLASH (Chip timing)
init_baudrate,
serial_init
checkcpu
misc_init_f #ifdef
init_func_i2c #ifdef
post_init_f #ifdef
init_func_ram -> calls init_dram board/netstal/hcu5/sdram.c
(EYE function removed!!)
test_dram call
* Reserve memory at end of RAM for (top down in that order):
* - kernel log buffer
* - protected RAM
* - LCD framebuffer
* - monitor code
* - board info struct
Save local variables to board info struct
call relocate_code() does not return
relocate_code: (cpu/ppc4xx/start.S)
-------------------------------------------------------
From now on our copy is in RAM and we will run from there,
starting with board_init_r
-------------------------------------------------------
board_init_r: (lib_ppc\board.c)
setup bd function pointers
trap_init
flash_init: (board/netstal/hcu5/flash.c)
/* setup for u-boot erase, update */
setup bd flash info
cpu_init_r: (cpu/ppc4xx/cpu_init.c)
peripheral chip select in using defines like
CFG_EBC_PB0A, CFG_EBC_PB0C from hcu5.h
mem_malloc_init
malloc_bin_reloc
spi_init (r or f)??? (CFG_ENV_IS_IN_EEPROM)
env_relocated
misc_init_r(bd): (board/netstal/hcu5.c)
ethaddr mit serial number erg<72>nzen
Then we will somehow go into the command loop
Most of the HW specific code for the HCU5 may be found in
include/configs/hcu5.h
board/netstal/hcu5/*
cpu/ppc4xx/*
lib_ppc/*
include/ppc440.h
Drivers for serial etc are found under drivers/
Don't ask question if you did not look at the README !!
Most CFG_* and CONFIG_* switches are mentioned/explained there.
