Hi,

we have synthesized Pulpissimo with Vivado (2018.3) to FPGA and with Design Compiler (2018) to silicon technology.
Now Pulpissimo code has been changed so, that Design Compiler can't synthesize it anymore.
Vivado synthesize it without issues.

Module LZC gives syntax error from this statement:
assign cnt_o   = NUM_LEVELS > unsigned'(0) ? index_nodes[0] : $clog2(WIDTH)'(0);

Also there is number of bus with conflicts which are quite painful to correct by user.

Can you make code cleaning and check that it passes Design Compiler?
I am also worried about quality of results in FPGA, because Vivado has not seen issues which exist.

Hi,
Currently I'm testing PULPino core on Altera DE10-Nano board. I want to use provided JTAG interface with Digilent HS-2 cable. There seem to be no documentation about connecting PULPino to OpenOCD anywhere so I thought to use slightly modified version of OpenOCD config from PULPissimo project as supposedly the debug interface is pretty much the same. Is it a valid assumption? So far I didn't get too far. In the attachment you can find my current OpenOCD config (I'm using your patched version based on PULPissimo README) and a log.
Is there some working solution so that it's possible to use PULPino with JTAG?

Greetings,
Marek

Hello,

What are the two registers REG_FCBOOT and REG_FCFETCH meant for? They are in Soc_control area. Basically in RTL code is said that they are not used, so because I would like to add a new register to soc_control area I was planning to use either of these . 
I would anyway like to make sure that I am not blocking anything that might be usefull later.

Hi,

We are using PULP 2.18  on a CentOS 7.6 server and currently synchronize a number of CentOS / RHEL 7 repositories. I have been trying to setup a new RHEL8  repo but seem to be getting "forbidden 403" errors.

I followed the below "how to" link which includes obtaining the required CACert/Cert/Key files from an existing registered RHEL8 server using Subscription manager but am having no joy. Could you please advise if i'm missing something? 

https://projectlinux.com/advancedpulp.php

Command used to create REPO...

pulp-admin rpm repo create --repo-id rhel-x86_64-server-8 --feed https://cdn.redhat.com/content/dist/rhel.../baseos/os --feed-ca-cert /root/repoconfig/certs/redhat-uep.pem --feed-cert /root/repoconfig/certs/8517629927282862959.pem --feed-key /root/repoconfig/certs/8517629927282862959-key.pem --generate-sqlite true --serve-http true --serve-https true --relative-url rhel/8/rhel-x86_64-server-8 --checksum-type sha256

Hello,

I'm trying to develop an application that loads some data from a file that is stored on the host computer. I found an example of doing this in the pulp-rt-examples/bridge/file, so I would like to simulate this in the GVSOC platform and pulp config file, but I'm not sure if I'm doing this in the correct way.

When I start running the example (make all clean run under pulp-rt-examples/bridge/file) I get this message from the console:
Proxy listening on port 37539

So what I do is to start a plpbridge on another terminal like this, which ends after 2 seconds or something like that:
plpbridge --config=pulp@config_file=chips/pulp/pulp.json reqloop --binary=./test

And in the first terminal, I get this new message:
Proxy: Client connected!


The thing is that after that, nothing else happens, the code seems to be frozen and nothing happens. Am I missing something?

Thanks a lot,
Ivan.

Hey, 


I am facing an issue with running the hwme example on pulpissimo both in bare metal code and FPGA. I had an earlier versions of RTL, SDK and I managed to run the example successfully on the platform. Now the code never reach the end of the code and print the number of errors. 

Are you aware with such a problem, what could be the source of this error ? I thinks there is a problem in plp_hwme_enable() function, it never passes this line. 

Thanks for your support !

Hi,

Hey All, 

I am trying to integrate NVDLA accelerator into PULPissimo platform through AXI4 interface. Has anyone done it before ? What's the limitations in terms of both hardware and software integration ? 

Thanks !

Hi,

we are using the ri5cy core, pulpinov1 branch, and wanted to understand which spike (isa simulator) repository should be taken.

i have found this:
https://github.com/pulp-platform/riscv-isa-sim
1. is there a specific branch matching the pulpinov1 design version
2. does it have any specific ri5cy compliance, special flags or any other?
3. am i supposed to take any patch to make it match ri5scy, as the toolchain?

for the toolchain, we are taking this :
https://github.com/pulp-platform/ri5cy_gnu_toolchain
which i understand patches the original pulp platform toolchain to match the ri5cy.

would appreciate any help on this topic.

thanks,
Itay K.
