U-Boot for MOUSSE/MPC8240 (KAHLUA) ---------------------------------- James Dougherty (jfd@broadcom.com), 09/10/01 The Broadcom/Vooha Mousse board is a 3U Compact PCI system board which uses the MPC8240, a 64MB SDRAM SIMM, and has onboard DEC 21143, NS16550 UART, an SGS M48T59Y TOD, and 4MB FLASH. See also: http://www.vooha.com/ * NVRAM setenv/printenv/savenv supported. * Date Command * Serial Console support * Network support * FLASH of kernel images is supported. * FLASH of U-Boot to onboard and PLCC boot region. * Kernel command line options from NVRAM is supported. * IP PNP options supported. U-Boot Loading... U-Boot 1.0.5 (Sep 10 2001 - 00:22:25) CPU: MPC8240 Revision 1.1 at 198 MHz: 16 kB I-Cache 16 kB D-Cache Board: MOUSSE MPC8240/KAHLUA - CHRP (MAP B) Built: Sep 10 2001 at 01:01:50 MPLD: Revision 127 Local Bus: 33 MHz RTC: M48T589 TOD/NVRAM (8176) bytes Current date/time: 9/10/2001 0:18:52 DRAM: 64 MB FLASH: 1.960 MB PCI: scanning bus0 ... bus dev fn venID devID class rev MBAR0 MBAR1 IPIN ILINE 00 00 00 1057 0003 060000 11 00000008 00000000 01 00 00 0d 00 1011 0019 020000 41 80000001 80000000 01 01 00 0e 00 105a 4d38 018000 01 a0000001 a0001001 01 03 In: serial Out: serial Err: serial Hit any key to stop autoboot: 0 => I.

IP Options which configure NFS Root/Boot Support root=/dev/nfs serverip=<NFS SERVER IP ADDRESS> nfsroot=<NFS SERVER IP ADDRESS>:/boot/root-fs V. U-Boot Image Support The U-Boot boot loader assumes that after you build your kernel (vmlinux), you will create a U-Boot image using the following commands or script: #!/bin/csh /bin/touch vmlinux.img /bin/rm vmlinux.img set path=($TOOLBASE/bin $path) set path=($U_BOOT/tools $path) powerpc-linux-objcopy -S -O binary vmlinux vmlinux.bin gzip -vf vmlinux.bin mkimage -A ppc -O linux -T kernel -C gzip -a 0 -e 0 -n vmlinux.bin.gz -d vmlinux.bin.gz vmlinux.img ls -l vmlinux.img VI. ONBOARD FLASH Support FLASH support is provided for the onboard FLASH chip Bootrom area. U-Boot is loaded into either the ROM boot region of the FLASH chip, after first being boot-strapped from a pre-progammed AMD29F040 PLCC bootrom. The PLCC needs to be programmed with a ROM burner using AMD 29F040 ROM parts and the u-boot.bin or u-boot.hex (S-Record) images. The PLCC overlays this same region of flash as the onboard FLASH, the jumper J100 is a chip-select for which flash chip you want to progam. When jumper J100 is connected to pins 2-3, you boot from PLCC FLASH. To bringup a system, simply flash a flash an AMD29F040 PLCC bootrom, and put this in the PLCC socket. Move jumper J100 to pins 2-3 and boot from the PLCC. Now, while the system is running, move Jumper J100 to pins 1-2 and follow the procedure below to FLASH a bootrom (u-boot.bin) image into the onboard bootrom region (AMD29LV160DB): tftp 100000 u-boot.bin protect off FFF00000 FFF7FFFF erase FFF00000 FFF7FFFF cp.b 100000 FFF00000 \${filesize}\ Here is an example: =>tftp 100000 u-boot.bin eth_halt eth0: DC21143 Ethernet adapter(bus=0, device=13, func=0) DEC Ethernet iobase=0x80000000 ARP broadcast 1 Filename 'u-boot.bin'.

TThe following commands will FLASH a bootrom (u-boot.bin) image into the onboard FLASH region (AMD29LV160DB 2MB FLASH): tftp 100000 u-boot.bin protect off FFF80000 FFFFFFFF erase FFF80000 FFFFFFFF cp.b 100000 FFF80000 \${filesize}\ C. FLASH KERNEL REGION (960KB) FLASH support is provided for the 960KB onboard FLASH1 segment. This allows flashing of kernel images which U-Boot can load and run (standalone) from the onboard FLASH chip. It also assumes The following commands will FLASH a kernel image to 0xffe10000 tftp 100000 vmlinux.img protect off FFE10000 FFEFFFFF erase FFE10000 FFEFFFFF cp.b 100000 FFE10000 \${filesize}\ reset Here is an example: =>tftp 100000 vmlinux.img eth_halt eth0: DC21143 Ethernet adapter(bus=0, device=13, func=0) DEC Ethernet iobase=0x80000000 ARP broadcast 1 TFTP from server 209.128.93.133; our IP address is 209.128.93.138 Filename 'vmlinux.img'.
