EVMK2H Out of box demo missing. Where do i get it?

Rajasekaran,

Thank you for the response -- it solved the issue. The u-boot change alone did not since the EVM didn't have the image in it. But following the instructions to obtain and load the OOB image worked (along with the u-boot change).

Hi,

I had to go through the process mentioned above, so I made a step by step list on how I succeeded.

(My board is Rev 3.0 with BMC 1.0.2.5 and did not contain the demo app.)

*****************************************************
Erase and burn NAND flash for Out of Box demo:
*****************************************************

IMPORTANT: Make sure the CCS GUI is not connected to the target, when running the Program evm scripts.

0. Set the DSS_SCRIPT_DIR environment variable to Code Composer Studio scripting bin directory. Default:

    set DSS_SCRIPT_DIR="C:\ti\ccsv5\ccs_base\scripting\bin"

1. DIP switch setting: 0001 (means No Boot)

2. Connect USB to daughter card

3. Power On. EVM display should output  'DSP No Boot'

4. Format the NAND flash: In Windows command line:

    cd <ti program_evm folder>    

    %DSS_SCRIPT_DIR%\dss.bat program_evm.js evmk2h format-nand

5. Burn nand.bit onto the flash device (will take minutes to load nand.bit):

    %DSS_SCRIPT_DIR%\dss.bat program_evm.js evmk2h nand

6. DIP switch setting: 0010 (ARM SPI Boot)

7. Connect USB to main board

8. Start Tera Term or Hyper terminal and set: 115200 baud rate, 8-bit data, 1-bit stop and no parity/flow control ( lower COM port #)

9. Power Cycle. U-Boot will show up (press any key to stop in u-boot)

10. if stopped in u-boot, carry on with:

    boot

11. Login to Linux, with 'root' login

12. Read ip address from EVM board or set up ip address, e.g.
    
    ifconfig eth0 192.168.2.81
    

13. Open browser and enter:

    192.168.2.81

*****************************************************************************

Once I could run the demo app from the NAND flash I thought I'd make the same thing but loading the image  via network this time.
I've set up a TFTP server, stopped the boot sequence in u-boot and entered:

 tftpboot 0x82000000 192.168.2.94:nand.bin

TCI6638 EVM # tftpboot 0x80700000 192.168.2.94:nand.bin

Using TCI6638_EMAC device
TFTP from server 192.168.2.94; our IP address is 192.168.2.100
Filename 'nand.bin'.
Load address: 0x82000000

Bytes transferred = 57802752 (3720000 hex)

The data transfer succeded, the boot sequence stopped here though. I believe it can be a wrong load address as I copied it from a tutorial for I didn't find it explicitly (http://processors.wiki.ti.com/index.php/MCSDK_UG_Chapter_Tools#Loading_and_Running_Linux_Kernel_using_tftp_with_initrd_file_system)

My questions regarding the booting would be the following:

1. How could I find the load address of the OOB demo?

2. What other environment parameters should be set for booting when using the tftpboot command?

Thanks a lot,

Janos

OK, So I realized that the question above has been quite silly, as the nand.bin is the Nand UBIFS image (keystone-evm-ubifs.ubi).

Can I extract the needed files from the nand.bin somehow to make it runnable via tftp?

Hi, Janos,

The OOB examples are in the file system. I am not sure what files you want to extract. If separate images, e.g. kernel, uboot, file system,  there are corresponding images in MCSDK release.  If one of the demo examples, you can use one of the following ways:

1) hook up console and tftp the files

2) expand the filesystem cpio file, tisdk-rootfs.cpio.gz, and copy it out from the folder.

You can see the boot environment setup if you reset the u-boot environment variables with "env default -f -a" command.

tftpboot uboot.bin only gets the file, not booting from it.

Hi, Jonas,

I just checked the User's Guide. Somehow a section of boot from network got removed. Before I restore that section of text, please do the following to boot from network:

env default -f -a
setenv boot net
setenv serverip <your tftp server IP>
setenv tftp_root <subdirectory from your server tftp root>
saveenv
boot

Rex

Thanks for the reply Rex!

'env default -f -a' works on random startups only, otherwise gives a warning and would not reset the parameters:

TCI6638 EVM # env default -f -a
WARNING: '-f' neither in running nor in imported env!
WARNING: '-a' neither in running nor in imported env!

However I managed to perform the operation, after a warm reboot there's a better chance to get it working, although I didn't find this definite.

For I am using separate dhcp and tftp servers I also had to modify the following env params, as when using the 'dhcp' command  not only a file is transferred but the 'serverip' parameter is also modified automatically, which I wanted to avoid. Therefore I swapped the 'dhcp' commands to 'tftp':

get_fdt_net=tftp ${addr_fdt} ${serverip}:${name_fdt}
get_kern_net=tftp ${addr_kern} ${serverip}:${name_kern}
get_mon_net=tftp ${addr_mon} ${serverip}:${name_mon}

The bootcmd:
bootcmd=run init_${boot} get_fdt_${boot} get_mon_${boot} get_kern_${boot} run_mon run_kern

On bootup the data transfer from the tftp is OK:

your bootarguments are setup for NFS boot. But either this was a mistake, or your kernel does not support NFS boot...

see:

[args_all=setenv bootargs console=ttyS0,115200n8 rootwait=1
args_net=setenv bootargs ${bootargs} rootfstype=nfs root=/dev/nfs rw nfsroot=${serverip}:${nfs_root},${nfs_options}]

and:

Jonas,

Your nfs_root points to /export and what do you have on the NFS server? As in my earlier post, you should use tisdk-rotofs.cpio.gz as your file system. Out-of-box demo is in that fs.

Thanks Rex for the reply again guys. I've changed the name_fs file system entry to tisdk-rootfs.cpio.gz, yet it still stops at the same stage during the boot process. The nfs_root points now to "/" as I copied the content of the factory-released "ti\mcsdk_linux_3_00_00_11\images\" folder to my tftp server root folder. The transfer of the files via tftp still succeeds and the linux startup commences.

I've noticed you had restored the User Guide entry on the network booting (Loading and Running Linux Kernel using tftp with NFS file system) I have configured accordingly.

However, my aim is not booting the OOB demo via ethernet but to boot up a default linux image. (And it doesn't really matter is if its the OOB or not). I'm not willing to build the kernel, only to use an image provided.
In BMC, ARM SPI is selected as the current bootmode ( as the NOR flash contains the U-Boot, and all the configurations discussed above can be set there). Is it possible however with the EVMK2H board to perform a bootup process selecting the ARM RBL ENET option in BMC? I could not find any guides on this. I reckon that the DHCP server needs  to send the u-boot image by default. Could you please point me to any guides on this?

Thanks  a lot,

Janos

You have configured tftp server correctly. Likewise, you have to configure to the Network File System server also.

In your case(from bootargs), you are trying to boot the device using network file system.

boot=net

1. Copy and Extract the file system image to setup the network file system.

2. Please update the nfs_root environment variable to use the extracted file system.

3. Configure and setup the network file system server to use NFS as described in below wiki link.

http://processors.wiki.ti.com/index.php/NFS_Setup

Please ensure that NFS is exported by running the command "sudo exportfs".  

Thanks.

Hi Janos,

Updated the above post. Apologize for the wrong information. 

Are you able to boot from NFS with above changes?

Thanks.

Thanks Rajasekaran for the support!

I have configured the nfs server just as it is described in the paper provided. Extracted the tisdk-rootfs.tar.gz to the export folder, set '/export' as nfs_root, still no progression, Dhcp, tftp, nfs servers, firewall all checked and OK.
 And although this is an issue, I'm more concerned on how the system could be booted without the need of flash memory device. To clarify my questions  I have started a new topic to avoid further confusion:

Thanks a lot!
