Starting UDHCP server at startup
Hi All, I wish to start the udhcp server at boot up through the start up script. I create a file S47udhcpd in /etc/init.d/ with the following contents: #!/bin/sh PKG="udhcp server" STARTCMD="/usr/sbin/udhcpd" STOPCMD="killall udhcpd" . /etc/init.d/common This is the last commond to be executed ie just before the linux prompt ask for the login and password. When I boot the system I get the following error message "SIOCGIFADDR failed, is the interface up and configured?: Cannot assign requested address." If I give the command "udhcpd" in my /etc/profile file the server starts. Why does this happen? If I am having this for a router I will need to run udhcpd the moment it comes...how will I do this?

Network Setup - HOW TO
Hi all, I have a custom router and ported the udhcp server/client on it. My router has 2 ports eth0 - LAN and eth1 - WAN. My setup is as follows: 1. To eth0: connect a stand alone windows machine when I run the server with the command "uphcpd", it by default runs on eth0. then on the windows machine when I say "ipconfig /renew", the router assigns an IP address to the system - perfect. 2. To eth0: connect to my company network. when I run the server with the command "uphcpd", it by default runs on eth0. then when I run the client "udhcpc" the router assigns an IP address to eth0 obtained from the company server - perfect. All this happens on eth0 ONLY. I wish to configure the router as follows: To eth0: stand alone system To eth1: company network The router should get an IP from my company server and assign it to eth1 and then it should assign a IP to my standalone system connected to eth0. how do I do this?

udhcp problem
My configuration is as follows: ___ |ROUTER | | ___ ___ | |_| |___| |___| LAN WAN /\ /\ | | Stand Alone Company Windows SystemNetwork (eth0) (eth1) I have a udhcp server running on eth0. When I give the command on the windows machine "ipconfig /renew", the router assigns an IP address to the System in the range 192.168.1.x while the router itself has the IP 192.168.1.1 (default). I can ping the router from the system and vice-versa. I manually assigned a static IP to eth1 as 172.19.56.x insync with the company IP address scheme. I can ping from the router to any other system on the network. Now when I try to ping a system or eth1 from the windows machine I get a time out. But if I have to manually assign an IP to the windows machine(ie not through the udhcp server) I am able to ping eth1 and any other system on the network. Any ideas as to how and why?

Is you netmask set right? Does /sbin/route show sane IP routes? What do you see on the wire? (Use Ethereal on a third computer). If you cannot ping then you've got a fundamental flaw in your configurations.

You need to run both dhcpd and dhcpcd. dhcpd to assign IP to your client. dhcpcd to get an IP from the network. It sounds like you need to brush up on your IP networking knowledge w/ linux. Go look at the howtos on www.tldp.org. Specifically on networking and DHCP. You should get this stuff working on a regular PC w/ 2 network cards running linux first before trying to get it going on your embedded board. Also, as I asked before, please include relevant output logs with your posts and I strongly recommend sniffing the Ethernet traffic with a tool like Ethereal. g.

Network Setup - HOW TO
My company uses the 172.19.x.x IP addresses, I want a PC with 192.168.x.x IP address to access the company network via a router. I have a router running Linux and having 2 Ethernet ports. I configured the systems in the following 2 ways: 1. Eth0 (LAN port) - 172.19.56.218 Eth1 (WAN port) - 172.19.56.219 Single System - 192.168.100.10 - IP Address 172.19.56.218 - Gateway 172.19.56.218 - DNS 2. Eth0 (LAN port) - 192.168.100.20 Eth1 (WAN port) - 172.19.56.219 Single System - 192.168.100.10 - IP Address 192.168.100.20 - Gateway 192.168.100.20 - DNS But I am not able to ping from the router to my single system in either way. How should I configure router to make this possible for the 2 networks to communicate?

Network Setup - HOW TO
Hi all, I have a custom board designed to function as a router. It has 2 Ethernet ports. Eth1 is a WAN port and Eth0 is a LAN port. This is what I wish to do: 1. connect the board/router to my company network 2. connect a normal system running windows or linux to the router 3. I should be able to ping or browse the net using the normal system via the router through the company network. I have connect the normal network cable (not a cross wire cable) between the router and the company network. The router does not seem to get a dynamic IP. Why and What should I do for it to get one? I assigned a static IP to eth1 and pinged another system on the company network and I do get a reply back. So my eth1 is working fine, but I would still prefer a dynamic IP. I connect a system to eth0 again with a normal network cable (not a cross wire cable) but the system does not seem to get an IP assigned even when I run the dhcp server on my routerused udhcpd command. Why and how can I get it up?

But I wanna to know how I can return to u-boot with software workaround after kernel hanging. At least, I must power-off and power-on my target to get back to u-boot console.

Linuxppc-embedded Digest, Vol 8, Issue 56
Hi Kishore,
There are various things you can try.
1. Check your log buffer...your console may not be initialized yet so
all your printk are logged at a particular memory location. Checkout the
System.map file in the Linux folder for "log_buf". The address that you
have there subtract it with the kernel base address. Then in view your
memory at that location. We used U-Boot so we gave the command
md
2. We used a tool called Code Warrior which helped us single step debug
the code, it didn't help us much though.
3. We had a problem with the RAM in burst mode. WolfGang would suggest
you check out if your RAM is operational. In our case we had to set some
flag in the U-Boot code for RAM in burst mode. We changed this flag and
it boots fine. Well almost.

It will be erased jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x0002: 0x0020 instead jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00020004: 0x22df instead jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x0002000c: 0x0008 instead And it ends with Cowardly refusing to erase blocks on filesystem with no valid JFFS2 nodes Kernel panic: VFS: Unable to mount root fs on 1f:00 <0>Rebooting in 180 seconds.. The reference board using an AMD flash works fine. I selected the ST Flash from make xconfig in Linux but the kernel crashes before it even calls start_kernel.

RAM test - How to
Hi, I am using a SDRAM having a port size 64 and size 32MB, and the burst length is 4. I want to know how i can test my RAM for burst mode operation. I have read in a couple of places that there is no sure RAM test but there must be some reasonable test which can be performed to atleast be sure that the RAM functions fine under burst mode.

Impact of change n port size
Hi All, I have a kernel image which works perfectly for my reference board. When I try to port the same image on my board I seem to be facing problems. The only difference I see between the reference board and my board is the port size and capacity of RAM. I have taken care of sending the right value for the RAM size through BD_INFO. Would there be and where all would the change be, if any, in the kernel code OR when I make the kernel image ie through "make menuconfig" / "menu xconfig" required to be made for port size of RAM? Out of curiosity what would be the change required for different FLASH port size again on the kernel side.

Problem with linux porting
Hi All, We are having a problem with porting of Linux. We are using the Linux kernel image modified to work on an EP8248 (having the MPC8248 Processor) Board. We have our board configured the same as the EP8248 board. We have made no changes to the Kernel Image and it crashes. The last message it shows on the console is "Uncompressing Kernelok" and the console log_buffer has the following: "<6>Memory BAT mapping: BAT2=32Mb, BAT3=0Mb, residual: 0Mb. <4>Oops: kernel access of bad area, sig: 11.<4>NIP: XER: LR: SP: REGS: c015 TRAP: Not tainted.<4>MSR: EE: 0PR: 0 FP: 0 ME:0 IR/DR: 00.<4> TASK = c014f470[0] 'swapper' Last syscall: 0 .<4>last math last altivec .<4>Call backtrace: 0004 ."

The value of IMAP_ADDR in linux/arch/ppc/platforms/ep8248.h and u-boot/include/configs/ep8248.h is 0xF000. The BD_INFO structure and the values are being passed perfectly from u-boot to Linux. The cmd_start and cmd_end are also perfect - verified using the memory dump command in u-boot. We have performed RAM test through u-boot and it has passed it. We would be grateful if somebody could throw more light on where we are going wrong and help us successful port Linux. If you require any more info i would be more than glad to provide you with the same.

Linux crashes during memory mapping
Hi All, I am trying to port the EP8248 Linux image (which works perfectly on the EP8248 board) on the VPN board (In house board) which is mpc8248 based board. I do not have any problem with the functioning of U-Boot but Linux crashes after printing "Uncompressing Kernel ... OK" and then it seems that nothing is happening. It would be great if u could help me resolve the issue. The following is how i have configured my board: 1. The value of the IMMR in HCRW is configured to 0xF000 (which is same as in the ep8248 image). The value of IMAP_ADDR in linux/arch/ppc/platforms/ep8248.h and u-boot/include/configs/ep8248.h is 0xF000 2. The memory map of EP8248 board (REFERENCE BOARD) is : = Memory RegionSize Address Range = SDRAM16MByte _ -- 07FF_ Flash8MByte FF80_ -- _ 3. The memory map of the VPN Board (MY BOARD) is as folllows: = Memory RegionSize Address Range == SDRAM32MByte _ -- 01FF_ Flash32MByte FF00_ -- _ >From the u-boot the parameters passed to the kernel (pointer to a function which actually starts loading the kernel image) are : (*kernel) (kbd, initrd_start, initrd_end, cmd_start, cmd_end); kbd(ptr to board info strcture), initrd_start (=0, as in our case we dont have any ramdisk), initrd_end (=0), cmd_start (Start of command line string), cmd_end (End of command line string) 4. Board Info Structure defined in u-boot (/include/asm-ppc/u-boot.h) and Linux (include/asm-ppc/ep8248.h) are the same and is passed correctly from u-boot to Linux. By putting some Printk's I had cheacked that control is reaching to the function mapin_ram(void) in file arch/ppc/mm/pgtable.c Here it is supposed to map the 32 MB of virtual memory to the Physical memory. The control does not leave the for loop in which the memory mapping takes place. This is what the console log buffer has shown: = md 0x00177e34 00177e34: 3c363e6d 73746172 743d303c 363e6d73<6>mstart=0<6>ms 00177e44: 697a653d 303c363e 66737461 72743d30ize=0<6>fstart=0 00177e54: 3c363e66 73697a65 3d303c36 3e696d6d<6>fsize=0<6>imm 00177e64: 723d303c 363e626f 74666c61 673d303cr=0<6>botflag=0< 00177e74: 363e6970 6164643d 303c363e 656164646>ipadd=0<6>eadd 00177e84: 3d633031 35303032 383c363e 65737065=c0150028<6>espe 00177e94: 643d303c 363e696e 6974663d 303c363ed=0<6>initf=0<6> 00177ea4: 62757366 3d303c36 3e63706d 663d303cbusf=0<6>cpmf=0< 00177eb4: 363e6272 67663d30 3c363e73 6363663d6>brgf=0<6>sccf= 00177ec4: 303c363e 76636f3d 303c363e 626175640<6>vco=0<6>baud 00177ed4: 3d304f6f 70733a20 6b65726e 656c2061=0Oops: kernel a 00177ee4: 63636573 73206f66 20626164 20617265ccess of bad are 00177ef4: 612c2073 69673a20 31310a3c 343e4e49a, sig: 11.<4>NI 00177f04: 503a2030 30303030 30303020 5845523aP: XER: 00177f14: 20303030 30303030 30204c52 3a203030 LR: 00 00177f24: 30303030 30302053 503a2030 3030303000 SP: 0 00177f34: 30303020 52454753 3a206330 31353030000 REGS: c01500 00177f44: 30302054 5241503a 20303030 3020202000 TRAP: 00177f54: 204e6f74 20746169 6e746564 0a3c343e Not tainted.<4> 00177f64: 4d53523a 20303030 30303030 30204545MSR: EE 00177f74: 3a203020 50523a20 30204650 3a203020: 0 PR: 0 FP: 0 00177f84: 4d453a20 30204952 2f44523a 2030300aME: 0 IR/DR: 00. 00177f94: 3c343e54 41534b20 3d206330 31346634<4>TASK = c014f4 00177fa4: 37305b30 5d202773 77617070 6572272070[0] 'swapper' 00177fb4: 4c617374 20737973 63616c6c 3a203020Last syscall: 0 00177fc4: 0a3c343e 6c617374 206d6174 68203030.<4>last math 00 00177fd4: 30303030 3030206c 61737420 616c746900 last alti 00177fe4: 76656320 30303030 30303030 0a3c343evec .<4> 00177ff4: 43616c6c 20626163 6b747261 63653a20Call backtrace: 00178004: 30303030 30303034 200a3c34 3e4f6f700004 .<4>Oop 00178014: 733a206b 65726e65 6c206163 63657373s: kernel access 00178024: 206f6620 62616420 61726561 2c207369 of bad area, si 00178034: 673a2031 310a3c34 3e4e4950 3a204330g: 11.<4>NIP: C0 00178044: 31353030 43302058 45523a20 433031351500C0 XER: C015 00178054: 30304138 204c523a 20303330 3030304300A8 LR: 03C 00178064: 30205350 3a203030 30333030 303120520 SP: 00030001 R 001
