[U-Boot-Users] OCOTEA tech details
by Andrew Wozniak 12 Aug '04

12 Aug '04

Hello everyone, We are porting U-Boot to a custom PPC440GX board and I was hoping to use the ocotea port of U-Boot as a starting point. It would be most helpful if I had a user manual for the ocotea with specific details about I/O devices, memory maps... Unfortunately, IBM's support site does not provide any technical literature for this board. A searched of the AMCC website turned up nothing - they had recently acquired the Intellectual Property and a Portfolio for the PPC4xx. Could anyone suggest where I can find the necessary technical details for the ocotea, to assist with my port? Best Regards, Andy Wozniak

[U-Boot-Users] nfs root issue
by Seingier François-Xavier 11 Aug '04

11 Aug '04

hello, now that u-boot works perfeclty alright on my EP405 board, I am testing some Linux features and am having problem with booting with a nfs root file system. I've googled around for hours now (and read the DULG manual too ;) and although this is not u-boot related, I guess some of you embedded guys may have encountered the same problem. If I use a ramdisk, I can mount the nfs partition (with -o nolock,nfsvers=2); so I'm running out of clues for now. The bootargs variable is set to: root=/dev/nfs IP=192.168.1.15:::::255.255.255.0::eth0 nfsroot=192.168.1.10:/opt/embedded/tools/ppc_4xx,v2 rw Any hint would be greatly appreciated. (and forgive me for sending this message on the u-boot list Wolfgang, but other mailing lists did not point me to working clues) During the boot process, I get: Looking up port of RPC 100003/2 on 192.168.1.10 RPC: rpc_getport_external(192.168.1.10, 100003, 2, 17) RPC: xprt_sendmsg(0) = -101 RPC: sendmsg returned error 101 portmap: RPC call returned error 101 Root-NFS: Unable to get nfsd port number from server, using default Looking up port of RPC 100005/1 on 192.168.1.10 RPC: rpc_getport_external(192.168.1.10, 100005, 1, 17) RPC: xprt_sendmsg(0) = -101 RPC: sendmsg returned error 101 portmap: RPC call returned error 101 Root-NFS: Unable to get mountd port number from server, using default RPC: xprt_sendmsg(0) = -101 RPC: sendmsg returned error 101 mount: RPC call returned error 101 Here are some information about the host: **** rpcinfo -p **** program vers proto port 100000 2 tcp 111 portmapper 100000 2 udp 111 portmapper 100011 1 udp 949 rquotad 100011 2 udp 949 rquotad 100011 1 tcp 952 rquotad 100011 2 tcp 952 rquotad 100003 2 udp 2049 nfs 100003 3 udp 2049 nfs 100021 1 udp 32773 nlockmgr 100021 3 udp 32773 nlockmgr 100021 4 udp 32773 nlockmgr 100005 1 udp 32774 mountd 100005 1 tcp 32789 mountd 100005 2 udp 32774 mountd 100005 2 tcp 32789 mountd 100005 3 udp 32774 mountd 100005 3 tcp 32789 mountd **** /etc/export **** /opt/embedded/tools/ppc_4xx *(rw,no_root_squash) **** /etc/hosts.allow **** # # hosts.allow This file describes the names of the hosts which are # allowed to use the local INET services, as decided # by the '/usr/sbin/tcpd' server. # ALL:ALL Regards, François-Xavier SEINGIER

[U-Boot-Users] u-boot environment variable setting: "console=ttyCPM0"
by Alex 11 Aug '04

11 Aug '04

Hi, I was recommended to use u-boot environment variable setting: "console=ttyCPM0" for loading linux-2.6.8-rc2 uImage (by u-boot) on to PQ2 ADS (with MPC 8270 on it). Could anyone knowledgeable ellaborate on usage of it for above described configuration ? What version of u-boot supports this setting ? What baud rate value I should add to this setting, if I want to use Hyperterminal serial connection ( over USB) to the board ? TIA, Alex

[U-Boot-Users] support moto mx1ads ?
by 刘涛 11 Aug '04

11 Aug '04

We are now developping a Embedded Linux project on Motorola i.MX ADS board. We use the u-boot as our bootloaderthe,the version of the u-boot we use is u-boot1.1.1,the latest version. But it seems do not support Motorola i.MX1 and Motorola MX1ADS board. Have any path for u-boot to support i.MX1 and MX1ADS bord. Thanks.

[U-Boot-Users] some problems with a 64360
by Amit Shah 10 Aug '04

10 Aug '04

Hi, I have a PCI board that as the MV64360 with a 750GX processor. It doesn't have ethernet interfaces. u-boot comes up on the board fine, but its behavior is erratic. On the host system, I have a device driver that exposes the SDRAM, flash, SRAM, etc, on the board via some /dev/ devices. When I start u-boot by clearing a bit in the Marvell registers that starts the processor from the host system, u-boot comes up, shows some serial output, and when it comes to autoboot, it just freezes. My autoboot command is 'bootm 0x40004' and I place the hello_world.bin in the SDRAM at that location, just prior to autoboot via the host machine by stopping u-boot momentarily by putting a getc(). I also tried disabling autoboot and directly jumping to 0x40004. Even this doesn't help. It just shows a bad trap panic. Once u-boot did manage to go through the 3-second timeout and jump to the binary. However, it reported 'unknown image format' or something like that. Since then, it hasn't gone to the timeout stage. I'm wondering if this is related to interrupts or serial output. I have some debug messages printf()ed in serial_tstc and serial_getchar. When I disable them, it just freezes, so I don't know when and how. When I enable them, I know it did something for some time. I can't use the BDI reliably too; I start the processor via the /dev interface, get u-boot till the getchar() adn then connect gdb via bdi. However, it'll just keep looping in getchar, and it'll be too long before it gets to the autoboot. I also won't notice if the execution just froze before it timed out. Any tips where things could be going wrong? Any debugging tips with BDI? Thanks for any help, Amit. -- Amit Shah http://amitshah.nav.to/

[U-Boot-Users] uboot compilation error when using the toolchain arm-elf-tools from uClinux.org
by Shawn Jin 10 Aug '04

10 Aug '04

Hi, I checked out u-boot code from CVS today and tried to compile it for ARM IntegratorCP board. The cross toolchain I used is arm-elf-tools downloaded from uClinux.org. Unfortunately I got the following compilation error. arm-elf-gcc -g -Os -fno-strict-aliasing -fno-common -ffixed-r8 -mshort-load-bytes -msoft-float -D__KERNEL__ -DTEXT_BASE=0x01000000 -I/u/code/denx/u-boot/include -fno-builtin -ffreestandin g -nostdinc -isystem /usr/local/lib/gcc-lib/arm-elf/2.95.3/include -pipe -DCONFIG_ARM -D__ARM__ - mapcs-32 -march=armv4 -Wall -Wstrict-prototypes -c -o cfi_flash.o cfi_flash.c In file included from cfi_flash.c:48: /u/code/denx/u-boot/include/asm/processor.h:52: parse error before `1' /u/code/denx/u-boot/include/asm/processor.h:52: warning: no semicolon at end of struct or union /u/code/denx/u-boot/include/asm/processor.h:54: parse error before `}' /u/code/denx/u-boot/include/asm/processor.h:58: field `insn' has incomplete type The code is extracted from the header file processor.h. 51> union debug_insn { 52> u32 arm; 53> u16 thumb; 54> }; 55> 56> struct debug_entry { 57> u32 address; 58> union debug_insn insn; 59> }; However I really don't think there is any syntax error. It might be a toolchain problem? -- Best regards, Shawn Jin

Re: [U-Boot-Users] Regarding Toolchain used for Compilation

Hi Denk.. ' Failing' means im not able to get any output on serial console. Compilation is successful but after flashing im not able to boot the board [MPC8540 based board] Thats why i asked the ques.. I'm new to U-boot and if some questions seems to be silly i apologize for that.

Hi, We are using MPC885ADS Eval. board ,we are porting U-Boot 1.1.1 on it and working fine, we have following query : We are connected an EEPROM (CHIP ADDRESS : 0X50) on I2C bus, when we trying to check with "iprobe" command its displaying a message like : Valid chip addresses: 00 01 02 03 04 05 06 07 ............ 80 Its talking a lots of time and not working. Has anyone faced same problem? thanks and regards, Sachin mehta
