Instructions for vc707 without PCIe #116

Closed mcd500 closed 5 years ago

mcd500 commented 5 years ago

This is not an issue, it is request for comments.

Do you mind anybody trying the branch in my repo for no pcie on vc707? I am planning to make a pull request when I have time to bump them up to latest in master.

The source and instruction of building Rocket for vc707 with no-pcie. The readme: https://github.com/mcd500/freedom/tree/vc707-nopci To build,

git clone https://github.com/mcd500/freedom.git
cd freedom
git checkout -b vc707-nopci remotes/origin/vc707-nopci
git submodule update --init --recursive --force
export RISCV=/home/riscv/riscv64-elf-tc <- please change it accordingly to your env
export PATH=${PATH}:/opt/Xilinx/Vivado/2016.4/bin <- please change it accordingly to your env
make -f Makefile.vc707-u500devkit nopcie
make -f Makefile.vc707-u500devkit verilog
make -f Makefile.vc707-u500devkit mcs

then write the bitstream to vc707.

The source and instruction of building linux of sd-boot image for vc707 with no-pcie. The readme: https://github.com/mcd500/freedom-u-sdk/tree/linux_u500vc707devkit_config To build,

git clone https://github.com/mcd500/freedom-u-sdk.git
cd freedom-u-sdk
git checkout -b linux_u500vc707devkit_config remotes/origin/linux_u500vc707devkit_config
git submodule update --init --recursive --force
cd buildroot
git checkout -b sifive remotes/origin/sifive
cd ..
make -j4 BOARD=vc707devkit_nopci

This will write the image to SD card.

make DISK=/dev/whereisSDcard vc707-sd-write

Please let me know if anything does not work, so I could revise it before I create pull request.

tmagik commented 5 years ago

@erikdanie is there any way we can support both VC707 configs (with and without the PCI HMC expansion) from the same bitstream?

erikdanie commented 5 years ago

I think this idea is good, and we need to make it easier to generate a no-pcie bitstream, but using sed in the makefile to comment out the line isn't the ideal way to do it. Instead, what should happen (and what I will do eventually when I get time, or if you want to try it on your own that would be awesome!) is that we should have 2 "shells" in VC707NewShell.scala. One class is the "VC707BasicShell", which includes all the peripherals and additions that are standard, and the other is "VC707PCIeShell", which extends VC707BasicShell, but then adds in the pcie. You can see an example of this in the master branch of fpga-shells in VCU118NewShell.scala. Then, in the makefile, depending on if the user passed in the "nopcie" argument, it would either do MODEL = VC707BasicShell or MODEL := VC707PCIeShell

Thanks for submitting this though! The makefile additions are helpful, and I'd merge those in separately if you were to put in a PR

mcd500 commented 5 years ago

Hi @tmagik and @erikdanie, thank you for the comments, I will revise them to use MODEL = VC707BasicShell or MODEL := VC707PCIeShell and make the pull request probably this weekend.

mcd500 commented 5 years ago

Hi @tmagik and @erikdanie, I pushed the changes to my repo. I removed using sed and it will use MODEL= with selecting the build for with/without PCIe board. The VC707BaseShell extends VC707BaseShell for selecting which bitstream to build. Is my change matches your thoughts?

$ git clone https://github.com/mcd500/freedom.git
$ cd freedom
$ git checkout vc707-nopcie-switchable-not-fully-tested-builds-ok
$ git submodule update --init --recursive --force
$ export RISCV=/home/riscv/riscv64-elf-tc <- please change it accordingly to your env
$ export PATH=${PATH}:/opt/Xilinx/Vivado/2016.4/bin <- please change it accordingly to your env

With PCIe-HMD board
$ make -f Makefile.vc707-u500devkit verilog
$ make -f Makefile.vc707-u500devkit mcs

For no PCIe-HMD board
$ make MODEL=VC707BaseShell -f Makefile.vc707-u500devkit verilog
$ make MODEL=VC707BaseShell -f Makefile.vc707-u500devkit mcs

The links are here. I tested and it looks working so might need to change the branch name before I make the pull request. https://github.com/mcd500/freedom/tree/vc707-nopcie-switchable-not-fully-tested-builds-ok https://github.com/mcd500/fpga-shells/commits/vc707-nopcie-switchable

Hi @tmagik and @erikdanie, I pushed the changes to my repo. I removed using sed and it will use MODEL= with selecting the build with/without PCIe board. The VC707BaseShell extends VC707BaseShell for selecting which bitstream to build. Is my changes matches your thoughts?

With PCIe-HMD board $ make -f Makefile.vc707-u500devkit verilog $ make -f Makefile.vc707-u500devkit mcs

For no PCIe-HMD board $ make MODEL=VC707BaseShell -f Makefile.vc707-u500devkit verilog $ make MODEL=VC707BaseShell -f Makefile.vc707-u500devkit mcs

The links are here. I tested and it looks working so might need to change the branch name before I make the pull request. https://github.com/mcd500/freedom/tree/vc707-nopcie-switchable-not-fully-tested-builds-ok https://github.com/mcd500/fpga-shells/commits/vc707-nopcie-switchable

This looks right to me. Does the build pass timing? I’ve had to slow some builds down to 100mhz clock to get it to pass timing without violations.

We also had a discussion today about moving from the FMC connector (which is quite expensive), and instead using an edge-card connector which I currently don’t have the part number or link for, and using the card-edge PCI, as it’s a lot simpler that way.

mcd500 commented 5 years ago

Hi @tmagik, yes the build passed the timing, the default was DevKitU500FPGADesign_WithDevKit50MHz in the Makefile.vc707-u500devkit. Running on 50MHz was perfectly fine. I also tried

$ make CONFIG=DevKitU500FPGADesign_WithDevKit100MHz MODEL=VC707BaseShell -f Makefile.vc707-u500devkit verilog
$ make CONFIG=DevKitU500FPGADesign_WithDevKit100MHz MODEL=VC707BaseShell -f Makefile.vc707-u500devkit mcs

and 

$ make CONFIG=DevKitU500FPGADesign_WithDevKit150MHz MODEL=VC707BaseShell -f Makefile.vc707-u500devkit verilog
$ make CONFIG=DevKitU500FPGADesign_WithDevKit150MHz MODEL=VC707BaseShell -f Makefile.vc707-u500devkit mcs

The 100MHz was no problem. The 150Mhz did not pass the timing on the build but the generated bitstream is working OK with 150Mhz so far :-)

@mcd500 Hello, I have tried your vc707-nopci and linux_u500vc707devkit_config on my vc707 board, it could show the sifive logo on boot, but then it did nothing. Then I have tried vc707-nopcie-switchable-not-fully-tested-builds-ok and vc707-nopcie-switchable, but both of them had the same result as the vc707-nopci. Do you have a clue of what is going on?

mcd500 commented 5 years ago

Hi @wwMark , not really, it was working on my place at the office. Did you tried the command I added bellow when you write to SD card?

sodo make DISK=/dev/whereisSDcard vc707-sd-write

since the bellow do not work for vc707.

sudo make DISK=/dev/sdX format-boot-loader

It is in the readme here. https://github.com/mcd500/freedom-u-sdk/tree/linux_u500vc707devkit_config

Hello @mcd500, I have tried with these commands, and they didn't work. Then my advisor tried them again, and everything succeeded now. We are trying to find out the reason. Thank you for your help.

rgb000000 commented 5 years ago

Hello @mcd500, thanks your work. Now, following your instructions I boot linux on VC707 without PCIe successfully. It's funny. But I am a newbie, I don't know how to run my program or accelerator, this Linux doesn't have some tools like gcc.So I ask for some advice about how to use this linux? Thanks in advance.

mcd500 commented 5 years ago

Hi @s1104439112 , the current Linux boot image for vc707 is buildroot which is not able to install packages with apt or yum tools. I am pretty busy at the moment, so I am not sure when I could post it here, creating Debian rootfs for vc707 will be able to install gcc and etc for development.

jalezeta commented 5 years ago

First of all thanks @mcd500 for your support. I can boot Linux without the external PCI clock. However, the eth0 port is not available, which I can appreciate it in your boot sequence as well (timeout message showing up). I guess this happens because we are not using the external PCIe NIC, which it would not work without the external PCIe clock generator. On top of that I do not see a reason why we need to use the external PCI clock generator since both clock frequencies in the range of 200MHz.

erikdanie commented 5 years ago

Your above statement is correct. The reason the external generator is used is to more easily sync the PCIe clock and reset with the board, plus I believe the oscillator on the PCIe card is supposed to be better than the one on the board by default.

jalezeta commented 5 years ago

Thank you @erikdanie for solving these doubts! Moreover, I am interested in compiling some c files on my ubuntu host with the risc-v linux toochain and run it in the Freedom implementation target which is running linux. The problem is that I cannot see my root file system in the sd in my host computer after running the command "sudo make DISK=/dev/whereisSDcard vc707-sd-write". Basically, I cannot even mount the SD card and see the root file system. But still, linux is booting up correctly in the VC707. I was thinking on sending the files through ethernet, but I cannot do it since we are not using PCI, thus, we cannot use the ethernet NIC. Is there any way of using the VC707 on-board ethernet port instead? I think this might be interesting for anyone who might want to use this implementation without PCIe. Thanks in advance!

mcd500 commented 5 years ago

Thanks, forgot to close this. The changes are merged at https://github.com/sifive/freedom/pull/118 and https://github.com/sifive/freedom/pull/133

Hi @mcd500 , does vc707BaseShell support interface eth0 ? When i boot the fpga board and connect to the host cpu via ethnet wire, it appears as follows:

starting network...
Waiting for interface eth0 to appear............... timeout!
run-parts: /etc/network/if-pre-up.d/wait_iface: exit status 1
Starting dropbear sshd: OK

How should I enable the eth0 interface in the fpga board? Looking forward to your reply.Thanks very much.

krabo0om commented 4 years ago

@minisparrow Hi, the FMC extension card offers a PCIe slot in which an ethernet card can be plugged. The on-board ethernet is not supported. You can have a look at the Ariane Pulp Plattform, they appear to have at least some support for the VC707 on-board ethernet. Please let me know if you get it working without extension cards.
