TEBF0808 booting from remote machine

[adamdunc]

Hi,

I am trying to establish a process for booting a kernel on the TE0808 from a remote machine and had a few questions.

1. Is there a way to build images in petalinux and then boot them all over JTAG with one command?

The command I am issuing that fails is:
petalinux-boot --jtag --bitstream ../Carrier_TEBF0808/vivado/Carrier_TEBF0808.runs/impl_1/zusys_wrapper.bit --kernel --pmufw no
I thought that this would work but I get an error "cma: Failed to reserve 128 MiB"
The full error log is below at the end of this post.

I can issue a similar command and boot into a U-boot shell and then do TFTBOOT successfully like so:
petalinux-boot --jtag --bitstream ../Carrier_TEBF0808/vivado/Carrier_TEBF0808.runs/impl_1/zusys_wrapper.bit --pmufw no --u-boot
then enter U-boot prompt, and type "run netboot"

2. Every once in a while the TEBF0808 system seems to get stuck in a weird state where I can download a bitstream just fine but I get a memory write error during download of the ELF file
The error goes away if I manually push the board reset switch and rerun the command, but I am not able to do this remotely. Is there a way to do the same kind of reset remotely? Ideally from a linux command line?

Hi,

can you check boot mode (DIP-Switch S5), is it set to JTAG boot?

br
John

[adamdunc]

John,

I have S5 set to 0000 which I believe should be the JTAG boot setting. The following command executes just fine:

petalinux-boot --jtag --bitstream ../Carrier_TEBF0808/vivado/Carrier_TEBF0808.runs/impl_1/zusys_wrapper.bit --pmufw no --u-boot

The command that does not execute OK is:
petalinux-boot --jtag --bitstream ../Carrier_TEBF0808/vivado/Carrier_TEBF0808.runs/impl_1/zusys_wrapper.bit --kernel --pmufw no

Thanks,
Adam

Hi,

I'm on Embedded World at the moment.  I will test this next week.

[adamdunc]

John,

Did you get a chance to test this?

Hi,

i will try this in the next days.
I never used petalinux to configure fpga.

br
John

[JH]

Hi,
did you try following command:

• petalinux-boot --jtag --prebuilt 3

For Zynq UltraScale+ MPSoC: Download the prebuilt FPGA bitstream, the prebuilt FSBL, the prebuilt PMUFW, the prebuilt ATF and the prebuilt kernel on target.

See page 27, 33:

• https://www.xilinx.com/support/documentation/sw_manuals/xilinx2016_4/ug1144-petalinux-tools-reference-guide.pdf

br John

[adamdunc]

John,

I tried the "petalinux-boot --jtag --prebuilt 3" and am still getting stuck after the BL31 line in the console. Have you verified this to work on your end?

Here are my specific steps and results:

I copied the following files from your 2016.4-build05 to the pre-built folder in my petalinux project:
Carrier_TEBF0808/prebuilt/software/te0808_es1_tebf0808/zynqmp_fsbl.elf to pre-built/linux/images/zynqmp_fsbl.elf
Carrier_TEBF0808/prebuilt/hardware/te0808_es1_tebf0808/Carrier_TEBF0808.bit to pre-built/linux/implementation/download.bit
Carrier_TEBF0808/prebuilt/os/petalinux/default/bl31.elf to pre-built/linux/images/bl31.elf
Carrier_TEBF0808/prebuilt/os/petalinux/default/image.ub to pre-built/linux/images/Image

I've not verified it, but i will do as soon as possible.
I've only read this in the documentation and I think it is worth trying out this.

Hi,

i try it at the moment, but i have a other problem at the moment with my vm.
https://www.xilinx.com/support/documentation/sw_manuals/xilinx2016_4/ug1144-petalinux-tools-reference-guide.pdf
Can you try following:

• Generate pre-built folder with(page 26) after you has run the petalinux build: petalinux-package --prebuilt --fpga ./images/linux/zusys_wrapper.bit
• PMUFW is not included automatically, copy manually:cp images/linux/pmufw.elf ./prebuilt/linux/images/
• Run: petalinux-boot --jtag --prebuilt 3

Does it work?
I try it when i solved my problem with vm
br

[JH]

Hi,

at the moment i can't startup JTAG with Linux on VM. I think there are problems with the driver, but in the moment I've not enough time to solve this problem. We only use WinOS for programming FPGA over JTAG.
So can you test the steps from my last post.

br
John

[adamdunc]

John,

I tried this and am still getting the same error. I have resorted back to loading files onto the SD card and booting from the SD card.

[JH]

Hi,

Ok, sorry that i can't help at the moment.

Of my own interest: Appears another warning wenn you add PMUFW? Or it's the same log as  Reply #7 on: March 23, 2017, 08:23:48 PM without the PMUFW warning?
