  REG_FCBOOT and REG_FCFETCH
Posted by: skor - 08-15-2019, 09:35 AM - Forum: PULP General questions - No Replies

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.


Regards,

skor

  RHEL8 repo sync's
Posted by: leepayne - 08-15-2019, 09:03 AM - Forum: PULP General questions - Replies (1)

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

  File reading from host example
Posted by: ivanfv - 08-09-2019, 02:33 PM - Forum: PULP General questions - No Replies

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.

  Issue with running the hwme example on pulpissimo
Posted by: AhmedZaky - 07-18-2019, 03:24 PM - Forum: PULP General questions - Replies (2)

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 !

  Error on Macro 'DMI_JTAG_IDCODE is not defined when built pulp RTL simulation pfm
Posted by: mapletree - 06-21-2019, 05:09 PM - Forum: PULP General questions - No Replies

Hi,
I am trying to build the pulp RTL simulaltion platform following the instructions provided on the github page:
https://github.com/pulp-platform/pulp.

At the steps:

Code:
source setup/vsim.sh
cd sim/
make clean lib build opt

I got the following error:
** Error: ../ips/pulp_soc/rtl/pulp_soc/pulp_soc.sv(800): (vlog-2163) Macro 'DMI_JTAG_IDCODE is not defined.

Does anyone ever get the same problem? is there a solution to fix it?

Thanks!

I replaced the pulp_soc_defines.sv with the one coming with pulpissimo platform that includes the definition of the DMI_JTAG_IDCODE, then the error is gone.

  which spike version for ri5cy?
Posted by: etayke - 06-11-2019, 02:52 PM - Forum: PULP General questions - No Replies

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.

  xilinx memories in pulpissimo L2

Hi,

In Pulpissimo in l2_ram_multi_bank.sv there is hooks for xilinx memories:
`ifdef PULP_FPGA_EMUL

      logic [NB_BANKS-1:0][7:0]   wea;

      genvar                      i,j;
      generate

         begin : CUTS
            for(j=0; j<8; j++)
            assign wea[i][j] = ~mem_slave[i].csn & ~mem_slave[i].wen & mem_slave[i].be[j];

            xilinx_l2_mem_8192x64 l2_mem_i (
               .clka  ( clk_i                                ),
               .rsta  ( ~rst_ni                              ),

               .douta ( mem_slave[i].rdata                   )
            );
         end
      endgenerate

Have you tested this is working?
