Hi all,

     I need to change the u-boot start address. As per my assumption u-boot start address is presented in PBL file.

     So I tried to change that address using QCVS tool but there i'm not getting any options for change the u-boot address.

     In that PBL file 1st 32bit is Preamble and 2nd 32bit is u-boot start address,

     [0000000: aa55 aa55 8010 0000 4028 2830 4040 0040

      0000010: 0000 0000 0000 0000 0000 0000 0020 0000]

      Is it correct or wrong?

     And help me on how to change the u-boot start address?

Thanks,

-Naveen

Please specify which processor you are talking about

Typically, for QorIQ processors, the core starts from fixed address, the only thing you can do in PBL remap this address to another address by address translation.

Hello naveennvn,

It's not correct. The second 32 bit 8010 0000 here is a PBI command "Load RCW with Checksum". The first byte 0x80 is a general command header and the second byte 0x10 is the CMD code.
