RBL source code for Keystone II

Raja,

Is the src code available with DNA?

If not, could you please check out for me what are the configuration differences when booting (ARM) RBL, between NAND flash and Ethernet boot?

We are having an instability issue with our custom board so that booting from ethernet does not work about 50% of the time. Nand booting is much more reliable.

Sorry, I mean NDA.

Hi Topi,
I will try to get those information from factory team.

In the meantime, please elaborate the ethernet boot issue so that we can support better.

Thank you.

Hi,

I have tested with two different setups:

1. RBL TFTP boot loading u-boot, which is booting Linux from TFTP server. This succeeds with about 50% probability. Failed boot ends with "Starting kernel ..." message.

2. RBL NAND boot loading u-boot (from flash), which is booting Linux from TFTP server. This succeeds with 100% probability.

Both setups are using the same u-boot and Linux versions.

Hi,

I tested exactly same binaries with Keystone II EVM, and the boot fails with about 30-40% probability.

Board is XTCIEVMK2X Rev 20.

BMC bootmode set to 0x115EEB.

Hi Topi,
Where is the file system stored? Is it NFS or UBIFS in both the setups?

I have confirmed with factory team that, as of now there is no plan to release RBL source of keystone II devices. Thank you.

Hi,

If you mean Linux file system, it is NFS. But that is irrelevant, as the hangout happens before NFS is mounted.

The point of hangout is just in the beginning of Linux startup. NFS is mounted far later, after DHCP response and lot of other stuff (which prints things on the console).

Hi Topi,
We will re-produce the issue at our end and get back to you. If possible post us the complete log for reference here. Thank you.

Hi,

I can send you our u-boot and kernel binaries. Please send your email-address or instructions to other means (of providing the files) to my email address.

BR, -Topi
