update to new MV linux kernel,but can not ping to server？？

not sure if I have ever pinged from target EVM linux prompt; I normally ping via u-boot prompt and that seems to work ok for me.  You may need to add proper file-system support to have the capability to ping from Linux prompt.

hello Juan

I can also ping to my server via u-boot prompt，but after logining use root ，it does not work。The messages given are：

PING 192.168.0.25 (192.168.0.25) 56(84) bytes of data.
From 192.168.0.84 icmp_seq=1 Destination Host Unreachable
From 192.168.0.84 icmp_seq=2 Destination Host Unreachable
From 192.168.0.84 icmp_seq=3 Destination Host Unreachable

--- 192.168.0.25 ping statistics ---
6 packets transmitted, 0 received, +3 errors, 100% packet loss, time 5013ms, pipe 3

As for file-system，I just use hard driver file-system.

I check the boot message，somethings strange are below：

。。。。

Thanks for any help！

Something definitely seems odd about those messages; are you using our DM6446 ECM made by Spectrum Digital?  I am thinking the missing MAC address my be the problem here; below is what my boot log looks like

Thank you,Juan

BTW,I use U-boot 1.1.3,does it matter?

I think the problem here is the missing MAC address; I am using u-boot 1.2.0 (so you may want to upgrade if you can), but if the MAC address is missing, I do not think the u-boot version would matter much.

I download all sofewares in www.ti.com.

Anther question，does the MAC addr read from u-boot argument：ethaddr，and we can change it to any number？although the MAC addr is deaddeaf，in linux prompt，the command “ifconfig” give the message

The mac addr is

08:00:28:32:06:08

but the ethaddr given is A0:BB:32:76:FE:01

Please note the MAC address should be printed on your DM6446 EVM; you can also download a utility at http://c6000.spectrumdigital.com/davincievm/revf/ to re-program the MAC address if it has been erased somehow, deadbeaf value shown in your boot log above does not sound like a good value

Thanks again ,Juan

First,How can I confirm  my board's mac address has been erased？I am puzzled ，assumed that the mac addr has been erased，why I can boot my old kernel MVL4.0，and get mac addr from the u-boot argument ethaddr，ping to server successfully.

second，I have download  DaVinciEVM_setmac.out，but I don't  know  how to use it，can you provide more help，thanks！

What u-boot version are you using with the new mv pro 5 dvsdk?   I would recommend you upgrade to the one included in the dvsdk release.   If you have not done this; it may explain why things work with mv pro 4 kernel but not w/ mv pro 5.

To be honest, I have never used DaVinciEVM_setmac.out, but going by the name, it appears this is a executable which you can load via CCS/JTAG.  I am guessing that when you load and run the executable, it will ask some questions such as value of MAC address and take over from there.  Of course, this is just a guess since I have never tried it.

With regards to kernels and bootloaders, I would not count on u-boot passing any information other then what is in bootargs to the kernel; I suppose it can pass MAC address set via u-boot variable, but I am not sure if this is the case.  The kernel can read the MAC address from EEPROM itself, hence it may not rely on u-boot value.  Furthermore, how the kernel gets MAC address may change from kernel to kernel... bottom line, making sure EEPROM has a valid MAC address is a good idea; it can help it will likely not make things any worse than they already are.

hello，Juan

Thanks for your response.

As  your advices，I update the uboot to version 1.2，and reset the board's mac address by what you guess.everything seems right.The message I get as below：

In CCS output,

Enter MAC address:   ( 00-0E-99-xx-xx-xx ) ( Last 3 numbers only [format:##-##-##])
00-0E-99-A0-00-00

Writing MAC address: ( 00-0E-99-00-0E-99 )
New MAC address set: ( 00-0E-99-00-0E-99 ) - Good!

Athough the result is not my input，it seems works.

BTW，I didn't update the HDD file system before，because I think it can instead of NFS，however，I update it too today. From the message，I know I lack modules.tar.gz. I don't know whether it matter my next works.Do you know where to download it？

Everything is ready. I boot the new kernel MVL5.0 via TFTP，use HDD fs and NAND mode.

。。。。。。。。。。。。。

TI DaVinci EMAC: MAC address is 00:0e:99:00:0e:99    ==================》the same as CCS output.
TI DaVinci EMAC Linux version updated 4.0
TI DaVinci EMAC: Installed 1 instances.
Linux video capture interface: v2.00

。。。。。。。。。。。。。

however，the sound card still not found.

What the important is I still can not ping my server.I use U-boot1.1.3 ，nor flash mode ，HDD fs to boot MVL5.0 again，the result is same.But I can ping my server in U-boot prompt and in MVL4.0 linux prompt . It seems something wrong in uImage-dm6446，but I confirm I get it from DVSDK2-00-00-22. I make my own kernel in default mode，it still can not ping my server.

I don't what to do next，and puzzled what is wrong.can you give me some more advice again?

Thanks again！

To be honest, I have not heard of modules.tar.gz; is this referenced in any of the docs? 

With regards to not being able to ping, I am puzzled myself as I am using pre-built kernel binary and can ping my host from my target EVM fine from both u-boot 1.20 and my mv pro 5 environment.  What file system are you using?  Is it the one that comes under 'momtavista/pro/devkit/arm/v5t_le/target' (per GSG)?  If not, try using this file-system.

Hello，Juan

Thank you so much .You always explain all issues definitely and patiently.

As for this problem，I think I neglect an important  thing .I use the board buyed from an TI authorized saler，but not TI raw board，and they use some different hardware.so I think the MVL5.0 kernel may not compatible to my board.This maybe my issure's reason.

I am so sorry，Juan.I think I must find it earlier ，but not just ask question.[:$]

mmm, not sure what to advice at this point.  Is there a web link (URL) to the board you are using?  For the most part, most of our third partied selling boards with our DaVinci parts provide the software for their particular board; have you tried going to them?

There is not URL ，they have not produced that board already.The DVSDK they provide is DVSDK1.1，a very old version，and did not update the DVSDK compatible to the board DM6446. I have connected them,but they have any practical support.

BTW,The company’name is SEED.

I have heard similar feedback on SEED from others.  Would you consider getting on of our DM6446 EVMs?  It may save you lots of head-aches and we would be able to offer much better support.
