  Hyperram Interface
Posted by: nemanja-rv - 12-29-2021, 05:39 PM - Forum: PULP General questions - Replies (2)

Hi all, 

I am new to the forum and like to say Hi to all. I've been looking into using Pulpissimo platform in one of my projects that I am currently working on and would like to ask for some help. At the moment, I am at the very early stage of the project. My intention is use to use very basic subset of the Pulpissimo platform so I would like to start by removing some things that I don't need.

Is there an easy way of removing Hyperram interface from the udma subsystem? I would potentially also want to remove Cam interface and I2S interface. My project will, most likely, be using SPI and SDIO interfaces as well as uart. 

Thanks. 

If there is already a thread addressing this topic, please refer. 

Best 
Nemanja

  How to clock gate the Pulpino
Posted by: CongHuang - 12-28-2021, 11:59 AM - Forum: PULP General questions - Replies (1)

Hello, team!

I am currently working on a project related to PULPino. I am wondering how to put the core in the IDLE state. The datasheet introduces an apb_event_unit for clock gating everything else and waking up the core if an event/interrupt arrives. I notice there is another peripheral, apb_pulpino contains CLK Gate as well. 
However, while running benchmarks such as hello/fft/sha/fir, I could not find the situations when the core is in the IDLE state. In other words, the clock signal is not gated during the entire operation. Is the clock gating function being enabled? Is there any benchmark I can use to test the clock gating (it would be better if the riscv-core and peripherals can be clock gated simultaneously)?

Thanks for your kind reply!

  Where's the data stored?
Posted by: zorrolee777 - 11-03-2021, 10:40 PM - Forum: PULP General questions - No Replies

Hello, 

Just a quick question about the pulpissimo.

We implemented pulpissimo on the zcu102 board, and successfully ran some examples using SDK. We would like to ask if we have such "int a = {1,2,3,4};" array in the program, for example, in the hello test, where would the array be stored? Is that stored in the 8kb ROM, or 512kb L2?

We are asking this because we could successfully define the array under the size of 175, but when we defined the array with a larger size (e.g. a = {0,0,0,0,0,0,0,0......0}), the program will be stuck.

Thanks,
Zongru

Question Distribution base_url display Packages config.repo repodata, expecting list of RPMs
Posted by: janr7 - 08-13-2021, 08:50 AM - Forum: PULP General questions - No Replies

Hello

We are moving to pulp3 from pulp2 without the migration path. Setting all up in a container.
Using pulp/squeezer

Using the base_url from the created distribution, the web page displays three lines as below.
Inside Packages are directories [0-1a-z] and the packages are in there.


I was expecting a list of packages.
Are there a way to have the URL display the list of packages on one page?
Thanks so much.

  Is that possible to boot Linux kernel on Pulpissimo with minor changes?
Posted by: ninipa - 08-04-2021, 07:25 AM - Forum: PULP General questions - Replies (1)

Hi Experts,

I'm wondering, is the original Pulpissimo on git be able to boot Linux kernel? (with RI5CY I guess)
If not, how can I achieve it with minor changes? (like replacing RI5CY with Ariane). I'm expecting not to use certain platform like FPGA. It's like I'm going to boot up Linux in simulation with Pulpissimo (despite of speed)

  How to get in64_t working as well as C++ builds
Posted by: Dom2231 - 06-30-2021, 01:57 PM - Forum: PULP General questions - Replies (2)

Hi everyone,

I'm currently working on my Master's thesis where I need to implement a software algorithm using 36 bit integers. My first approach was using the int64_t C type to represent my number. While it all worked fine on my local machine the algorithm broke in the Pulpissimo simulator.

After a while of debugging I figured out that the int64_t type does not work for me. To get started I modified `pulp-rt-examples/hello/test.c` to the code printed below, which is also a small example showing the issue that int64_t types always return the same value. I'm not sure whether this is a bug or I need to reconfigure something.

Do you have any idea how to solve this? Maybe I need to activate some compile flag or is there some 64-bit extension that I could easily add to the processor core?

I saw that the compiler does also support C++ so I wanted to give this a try but I couldn't find an example project to see how I can get the C++ compiler running. Simply changing the file extension from *.c to *.cpp did not work unfortunately.

Thank you very much Smile

BR
Dominik


Code:
#include <stdint.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>

int main()
{
 // Everything works when changing
 // int64_t to int32_t
 int64_t foo = 42;

 // Prints 0 instead of 42
 printf("\r\n%ld\r\n", foo);

 return 0;
}

Information *OpenOCD compilation errors WITH SOLUTIONS*

Compiling OpenOCD (with gcc (Ubuntu 9.3.0-17ubuntu1~20.04) 9.3.0) as described in https://github.com/pulp-platform/pulpiss...l-platform, section "GDB and OpenOCD":

Code:

Quote:  should be changed to

   
Code:

    Current gcc compiler flags this with an out of bound warning. In combination with the "Werror" flag, the compilation will be aborted.


After fixing that error, this one appears:

                break;
     



Posted here so you don't have to waste the time we did. After that, the compilation works. Good luck.

  Pulpissimo porting to Zephyr RTOS
Posted by: RiscV - 06-18-2021, 05:48 AM - Forum: PULP General questions - Replies (2)

Hi team,
I am trying to run pulp-rt examples on the Zephyr platform, but I didn't find any documentation regarding this.
Is pulpissimo run on Zephyr RTOS?  If pulp supports Zephyr, can you help me to find the documentation/steps? Your help in this regard is highly appreciated.

Thanks in advance

Pls help me in solving this.I want only project which satisfy other condition also(like banglore, pune,c and s).
is there anyother way of solving this?
i m not sue about my solution and way of solving.plz help.
