    MicroZed TFTP boot

      Hi,

      How do I change the TFTP boot server in uBoot please?

       

      Doing:

      Zynq> setenv serverip 192.168.1.107

      Zynq> printenv serverip

      serverip=192.168.1.107

      Zync> saveenv

      Saving Environment to SPI Flash... Erasing SPI flash...Writing to SPI flash...done

      OK

       

      Then booting, for example:

      petalinux-boot --jtag --prebuilt 2

       

      I get several:

      TFTP from server 192.168.1.254; our IP address is 192.168.1.183

      Filename 'pxelinux.cfg/default'.

      Load address: 0x2000000

      Loading: *

      TFTP server died; starting again

      Config file not found

      BOOTP broadcast 1

      DHCP client bound to address 192.168.1.183 (102 ms)

      Using ethernet@e000b000 device

      TFTP from server 192.168.1.254; our IP address is 192.168.1.183

      Filename 'boot.scr.uimg'.

      Load address: 0x3000000

      Loading: *

      TFTP server died; starting again

      BOOTP broadcast 1

      DHCP client bound to address 192.168.1.183 (145 ms)

      Using ethernet@e000b000 device

      TFTP from server 192.168.1.254; our IP address is 192.168.1.183

      Filename 'boot.scr.uimg'.

      Load address: 0x2000000

      Loading: *

      TFTP server died; starting again

       

      So it is trying to boot from 192.168.1.254, not 192.168.1.107.

      Probably me doing something silly, any help appreciated,

      Thanks,

      Dave.

          Oh, just noticed, the boot is failing at the start anyway, maybe the boot sequence is "failing over" to try other boot sources?

           

          So, doing:

          $ petalinux-boot --jtag --prebuilt 3

          boots the prebuilt images OK.

          ## Booting kernel from Legacy Image at 00200000 ...

             Image Name:   Linux-5.4.0-xilinx-v2020.1

          Starting kernel ...

           

          but doing:

          $ petalinux-boot --jtag --prebuilt 2

          fails, with...

          ## Executing script at 03000000

          Wrong image format for "source" command

          SCRIPT FAILED: continuing...

          and doing:

          $ petalinux-boot --jtag --kernel

          fails with:

          ## Executing script at 03000000

          There's probably a lot I've got wrong and don't know, any pointers please?

          Thanks,
