Hello,

I found a word document describing the HWPE Interface Specification, Rev 1.2, written in January 2018. by Francesco Conti.
I would like to use the microcode capabilities of the HWPE so I read there, since in the online Interface specification I couldn't find anything about it.
In this document, there was a mention of a Pythong script ucode_compile.py that should be able to compile some high-level code for the microcode processor.
Unfortunately, I could not find it so I have a few questions now.

Is the Microcode processor in the HWPE usable?
Is there somewhere such a "compiler" for microcode?
If it should be hardcoded, is there a specification of the instruction encoding? I found very little information about this in the document.

Thank you in advance!

Hello,

I was wondering how to decrease the number of cores in a cluster. I have found where to do it for the hardware (bigpulp/fe/rtl/includes/pulp_soc_defines.sv) but I'm not sure if that is all that is needed to be done or should there be something changed elsewhere?
Is there anything that needs to be changed in the HERO SDK?

Thanks,
Luka

hello，
I follow the steps at https://github.com/pulp-platform/pulp-sdk and want to create an SDK for PULPino. When I proceed to the "Target and platform selection" step, I want to find pulpino.sh in the config folder and source it, but I found that there is no such file. How should I build SDK for PULPino? Or does PULPino  need to build SDK?

hello，

My Linux distribution is Ubuntu 18.04. I followed the commands $ pip --version and $ python3 --version to check if the Python3 and pip3 versions match. The result is:

Lee@lee:~$ pip --version
Pip 9.0.1 from /usr/lib/python2.7/dist-packages (python 2.7)

Lee@lee:~$ python3 --version
Python 3.6.7

The results obtained seem to imply that the two versions do not match, but I have run the following commands to make them match:

$ sudo python3 -m pip install --upgrade pip
$ sudo python3 -m pip install artifactory twisted prettytable sqlalchemy pyelftools openpyxl xlsxwriter pyyaml numpy configparser pyvcd

What is wrong with it?

PS: When I run pip3 --version, the result is:
Pip 19.0.3 from /usr/local/lib/python3.6/dist-packages/pip (python 3.6)

Hi,

there is no too much documentation in pulp-soc-defines.sv file. So could you clarify next statement:

// PE selection (only for non-FPGA - otherwise selected via PULP_CORE env variable)
// -> define RISCV for RISC-V processor
//`define RISCV

//PARAMETRES
`define NB_CLUSTERS   1
`define NB_CORES      8
`define NB_DMAS       4
`define NB_MPERIPHS   1
`define NB_SPERIPHS   8

-> Does this mean that in normal configuration there is 8 cores if?

When I tested gcc according to the "test suit" in the readme at https://github.com/pulp-platform/pulp-ri...-toolchain, after running the command "make check-gcc-newlib", it appeared  " /bin/sh: line 17: runtest: command not found",  is this problem serious? What is the reason, how to fix it?

hello，

When I compiled the toolchain according to the steps in https://github.com/pulp-platform/pulp-ri...-toolchain, I encountered the following error:
/tmp/ccIifWI0.s: Assembler messages:

Since I am going to install the cross complier to /home/lee/Downloads/complier, so I run the commands below ：
1./configure --prefix=/home/lee/Downloads/complier --with-arch=rv32g --with-abi=ilp32d
2.make linux


 Is the install path chosen like this? Why is there such an error? How can I resolve these errors?

Hi, 

I am currently trying to use PULPissimo and the hello example runs fine, however when I try to run hwme example I got this error: 

" [/sys/board/chip/soc/fc/warning                   ] Invalid access (offset: 0x1a10c004, size: 0x4, is_write: 0)" 

Also Modelsim gui doesn't open when I use this command for hello example " make clean all run gui=1 " 

Can anyone passed this help in figuring out what's the problem ? 


Thanks in advance.

Hi,
