FPGA Manager + FSBL bitstream (Petalinux 2019.2)

[user9995]

Hi,

I've noticed that when I enable FPGA manager in petalinux configuration, petalinux-package does not allow loading a bitstream into BOOT.BIN for the FSBL to load. What is the reason for this limitation?

So does this mean if you want to dynamically load the PL from linux after boot you can can no longer have the PL loaded during FSBL or U-BOOT?

I'm using petalinux tools 2019.2 targetting a MPSOC.

Thanks,
Paul

Hi @user9995 

I don't think it should be like that. Could you post your logs after running petalinux-package command?

Hi @chaoz 

output after running "petalinux-package --boot --fpga --u-boot --pmufw --force"

First line gives warning that it does not insert bitstream into BOOT.BIN

You can also see this in the bif generated during package that it does not contain the bitstream:

the_ROM_image:

        [bootloader, destination_cpu=a53-0] /tmp/tmp.XjhYr1MWLL/zynqmp_fsbl.elf

hi @user9995 

Ok, if you need, you can try with Bootgen directly or using SDK to do the package.

Maybe tool is getting smartter...

[user9995 · Accepted solution]

Running bootgen directy did seem to work. However it seems you don't need FPGA manager enabled in petalinux-config to load bin files internally (kernel driver is still enabled). When its disabled then petalinux-package seems to let you insert bit files into BOOT.BIN.
