Creating BIN image:
| Warning | ||
|---|---|---|

Users must make sure that the BIT file used to create the BIN file was created in the same Vivado version as the Petalinux (or Yocto branch) used to create the Linux Image |

proc gen_bin {bit} {
set filename [file rootname [file tail $bit]].bif
set fileId [open $filename "w"]
puts $fileId "all:"
puts $fileId "{"
puts $fileId " $bit"
puts $fileId "}"
close $fileId
exec bootgen -w on -image $filename -arch zynqmp -process_bitstream bin
puts "$filename created successfully"

Sending BIN file over FTP:
Setup server on PC:
I used pumpkin, however, and TFTP server can be used:

Users can get the image size from the log after tftpboot |
Loading bitstream from TFTP automatically in u-boot:
There is a few ways that this can be achieved. The easiest would be to create a u-boot script with the commands similar to above to load the PL from TFTP.
