Failing to reproduce the NaxRiscv/Debian setup

I am trying to reproduce the NaxRiscv/Debian setup as described here and am running into some issues.

Steps I have untertaken:

Downloaded the files from the google drive and put them on an sd-card according to the instructions.
Created the gateware:

python3 -m litex_boards.targets.digilent_nexys_video --build --no-compile-gateware \
    --cpu-type=naxriscv \
    --bus-standard axi-lite \
    --with-video-framebuffer \
    --with-spi-sdcard \
    --with-ethernet \
    --xlen=64 --scala-args='rvc=true,rvf=true,rvd=true' \
    --csr-csv $HOME/build/csr.csv \
    --csr-json $HOME/build/csr.json

Created the bitstream using Vivado 2023.2
Loaded the bitstream to my Digilent Nexys Video board

openFPGALoader -b nexysVideo --freq 15M digilent_nexys_video.bin

First issue

The fist issue I ran into is a "hang" after printing the memory write speed. Pressing reset the first time leads to a "hang" at the same spot. After pressing reset a second time the boot continues and I am running into the second issue.

Second issue

When the boot continues, files are loaded from the sd-card into memory, OpenSBI and the kernel are starting. However the kernel gets hung up on litespi_rxtx, see the logs below.

This is bitstream I am using: digilent_nexys_video.bin.gz

Hope you can help me, I really would like to get this working.

Hi,

1) Yes i noticed that sometime, there is some weird hang in the litex bios, so far after doing reset it goes away most of the time. I didn't tracked the exact source of the issue so far.

2) Ahh i recently tested using https://github.com/SpinalHDL/NaxSoftware/blob/main/debian_litex/README.md which use the native MMC litex interface (not the SPI one)

What kernel were you using ? all the ones from the readthedoc ? you didn't recompiled anything right ? Maybe the address mapping of the SPI peripheral moved. What dts are you using / does the spi controller address of the generated soc match the dts/dtb you are using ?

Note, i'm mostly based on https://github.com/SpinalHDL/NaxSoftware/blob/main/debian_litex/README.md

Thanks for your quick reaction.

Reassuring to hear that you experienced the same bios/boot hang. I was wondering whether it may be a problem with my board. Not a major issue, but it would be nice if we could resolve it.

I was indeed using all the files from the readthedoc, including the dtb. And your guess was correct, the address mapping of the SPI has moved from spi@f0004800 to spi@f0005800.

After updating the dts and putting the corresponding dtb on the card, I was able to boot debian. Nice! Thanks!

I will now try to create a system based on your newer instructions.

Nice :D

Thanks for the update. Let's me know if you have any issue with the new instructions / there is missing information, especialy on the litex side of things.

I started with upgrading my config to the new instructions on step at a time:

opensbi
kernel
naxriscv bitstream with dma/non-spi sd/multi cpu
rootfs

Upgrading the opensbi was not successful. This is what I did:

(I changed the CROSS_COMPILE to riscv64-unknown-elf-)

git clone https://github.com/litex-hub/opensbi --branch 1.3.1-linux-on-litex-vexriscv
cd opensbi/
make CROSS_COMPILE=riscv64-unknown-elf- PLATFORM=litex/vexriscv
cp build/platform/litex/vexriscv/firmware/fw_jump.bin ../part1/opensbi.bin

This leads to a hang at liftoff:

What I find strange is that you create the opensbi with the config of VexRiscv, which leads to a 32-bit executable.

Then I created the new linux 6.1-rc2 linux kernel per your instructions, which went fine and booted correctly with the old opensbi:

I will now start working on updating the bitstreams, but wanted to let you know about my progress and hear your ideas on the opensbi issue.

Ahhhh right, i had some local changes about opensbi. I created a fork, and changed the readme instructions. with that updated https://github.com/SpinalHDL/NaxSoftware/blob/main/debian_litex/README.md#compile-opensbi it should be good. Let's me know ^^

That solved it:

Hi,

I didn't had particular with ethernet in debian, could it be aswell that the DTS memory address / interrupt id for the ethernet peripheral changed ? Can you check the eth0 stats ? (ifconfig eth0) RX packets 55249 bytes 65328784 (65.3 MB) RX errors 0 dropped 300 overruns 0 frame 0 TX packets 12857 bytes 2470859 (2.4 MB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

to see if the trafic goes both way

For your information my setup is now as follows. I created the bitmap using the following command:

python3 -m litex_boards.targets.digilent_nexys_video --build --no-compile-gateware \
    --cpu-type=naxriscv \
    --bus-standard axi-lite \
    --with-video-framebuffer \
    --with-coherent-dma \
    --with-sdcard \
    --with-ethernet \
    --xlen=64 --scala-args='rvc=true,rvf=true,rvd=true,alu-count=2,decode-count=2' \
    --uart-baudrate 3000000 \
    --with-jtag-tap \
    --sys-clk-freq 75000000 \
    --cpu-count 2 \
    --csr-csv $HOME/build/csr.csv \
    --csr-json $HOME/build/csr.json

I reduced the speed to 75MHz as I noticed that Vivado signals that timing cannot be met at 100MHz. At 75MHz the booting hangs are completely resolved and I can use the SD card in non-SPI mode. At 100MHz the core was unable to read the files reliable from SD to bootstrap everything. And I increased the serial speed to 3Mbps (for serial boots).

The dts is generated from csr.json, with the following modifications:

CPU ISA changed to rv64imafdc
Memory starts at 0x41000000 length reduced to 0x1f000000
Reserved memory areas removed
LEDs removed
Chosen initrd fields removed
Bootargs set to console=hvc0 earlycon=sbi root=/dev/mmcblk0p2 rootfstype=ext4 rw swiotlb=noforce rootwait rcupdate.rcu_cpu_stall_timeout=2

These are all the files I use, if you want to reproduce:

naxriscv.tar.gz

75MHz

Ahh maybe on my devkit i more lucky, (vivado give me slack violation of around -0.6 ns)

One thing you can do to increase fmax is to set alu-count=1,decode-count=1 instead

The thing which is botthering with vivado, is that -0.6 ns violation mean it could run at 94 Mhz. But when i change setting to 90 Mhz, then vivado relax too much and still get timing violation XD maybe the best would be to fake a higher clock frequancy to vivado than what it realy is to stress him well

Ahhh one thing to diagnostic is : cat /proc/interrupts

To see if interrupts happen or not.

Interrupts info:

I was wondering if you can reproduce with the files I provided.

hmm doesn't look bad. I will give a try.

I can reproduce the network issue on my side aswell now XD I'm trying to find the cause.

It seems related to a litex update which broke the peripheral interconnect. https://github.com/enjoy-digital/litex/issues/1831

There was a fix in litex upstream which fixed most of it, but apparentlyit may not have fixed it all, as reverting to https://github.com/Dolu1990/litex.git 5e482d64 fix the issue on my board.

Note if you try to revert litex to https://github.com/Dolu1990/litex.git 5e482d64 i had to change litex-boards/litex_boards/targets/digilent_nexys_video.py pll.create_clkout(self.cd_sys, sys_clk_freq, reset_buf="bufg") into pll.create_clkout(self.cd_sys, sys_clk_freq)

Thanks for testing and finding the problem so quickly. I will try to revert to the mentioned commit.

Last week I was able to get networking running with reverting to the commit you mentioned and modifying the board file. Will try the "official fix" this week.

Hi,

I had time to test. With litex upstream all seems good now. Also, it seems it may have fixed the random freeze i had in litex bios / early linux boot. (@100 Mhz)

let's me know how things goes on your side :D

Working for me as well. But only tested at 75MHz.

Will test for 100Mhz later and report back. Thanks again.

With 100Mhz, indeed the memory hangs seem to be resolved. However, the lite-x bios fails to recognize my SD-card in non-SPI mode or has read failures, so not usable for me at 100MHz.

Ahh on my side, critical path is on the SDcard side of things :
