Overview
=========
C29XPCIE board is a series of Freescale PCIe add-in cards to perform
as public key crypto accelerator or secure key management module.
It includes C293PCIE board, C293PCIE board and C291PCIE board.
The Freescale C29x family is a high performance crypto co-processor.
It combines a single e500v2 core with necessary SEC engines.
(maximum core frequency 1000/1200 MHz).
The C29xPCIE board features are as follows:
Memory subsystem:
- 512Mbyte unbuffered DDR3 SDRAM discrete devices (32-bit bus)
- 64 Mbyte NOR flash single-chip memory
- 4 Gbyte NAND flash memory
- 1 Mbit AT24C1024 I2C EEPROM
- 16 Mbyte SPI memory
Interfaces:
- 10/100/1000 BaseT Ethernet ports:
- eTSEC1, RGMII: one 10/100/1000 port
- eTSEC2, RGMII: one 10/100/1000 port
- DUART interface:
- DUART interface: supports two UARTs up to 115200 bps for
console display
Board connectors:
- Mini-ITX power supply connector
- JTAG/COP for debugging
Physical Memory Map on C29xPCIE
===============================
Address Start Address End Memory type
0x0_0000_0000 - 0x0_1fff_ffff 512MB DDR
0xc_0000_0000 - 0xc_8fff_ffff 256MB PCIE memory
0xf_ec00_0000 - 0xf_efff_ffff 64MB NOR flash
0xf_ffb0_0000 - 0xf_ffb7_ffff 512KB SRAM
0xf_ffc0_0000 - 0xf_ffc0_ffff 64KB PCIE IO
0xf_ffdf_0000 - 0xf_ffdf_0fff 4KB CPLD
0xf_ffe0_0000 - 0xf_ffef_ffff 1MB CCSR
Serial Port Configuration on C29xPCIE
=====================================
Configure the serial port of the attached computer with the following values:
-Data rate: 115200 bps
-Number of data bits: 8
-Parity: None
-Number of Stop bits: 1
-Flow Control: Hardware/None
Settings of DIP-switch
======================
SW5[1:4]= 1111 and SW5[6]=0 for boot from 16bit NOR flash
SW5[1:4]= 0110 and SW5[6]=0 for boot from SPI flash
Note: 1 stands for 'off', 0 stands for 'on'
Build and program u-boot to NOR flash
==================================
1. Build u-boot.bin image example:
export ARCH=powerpc
export CROSS_COMPILE=/your_path/powerpc-linux-gnu-
make C293PCIE
2. Program u-boot.bin into NOR flash
=> tftp $loadaddr $uboot
=> protect off eff80000 +$filesize
=> erase eff80000 +$filesize
=> cp.b $loadaddr eff80000 $filesize
3. Check SW5[1:4]= 1111 and SW5[6]=0, then power on.
Alternate NOR bank
==================
There are four banks in C29XPCIE board, example to change bank booting:
1. Program u-boot.bin into alternate NOR bank
=> tftp $loadaddr $uboot
=> protect off e9f80000 +$filesize
=> erase e9f80000 +$filesize
=> cp.b $loadaddr e9f80000 $filesize
2. Switch to alternate NOR bank
=> cpld_cmd reset altbank [bank]
- [bank] bank value select 1-4
- bank 1 on the flash 0x0000000~0x0ffffff
- bank 2 on the flash 0x1000000~0x1ffffff
- bank 3 on the flash 0x2000000~0x2ffffff
- bank 4 on the flash 0x3000000~0x3ffffff
or set SW5[7]= ON/OFF and SW5[7]= ON/OFF, then power on again.
Build and program u-boot to SPI flash
==================================
1. Build u-boot-spi.bin image
make C29xPCIE_SPIFLASH_config; make
Need the boot_format tool to generate u-boot-spi.bin from the u-boot.bin.
2. Program u-boot-spi.bin into SPI flash
=> tftp $loadaddr $uboot-spi
=> sf erase 0 100000
=> sf write $loadaddr 0 $filesize
3. Check SW5[1:4]= 0110 and SW5[6]=0, then power on.
