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

Hello good members!
I've recently started working with pulp platform and ran MobileNet application available on both dory and pulp-sdk by following the instructions given on github. It was a successful test however i am not able to understand from where the input values are taken or generated and i wanted to modify the input image size and see the output. can anyone help me understand.

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.


base-url result:

• Packages/
  
• config.repo
  
• repodata/
  

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)

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

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":

Quote:  In src/flash/mflash.h the line

Quote:  should be changed to

Quote:This is obviously an error, since in mflash.c reserved7 is accessed using
    memset(pSegIdDrvInfo->reserved7, 0x00, 190);

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

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

I tried soe code:

    prob = LpProblem("choose project")
    project_list = list(df['project'])
    banglore = dict(zip(project_list,df['loc_Bangalore']))
    pune = dict(zip(project_list,df['loc_Pune']))

    no_of_project_choose = 5
    prob += pulp.lpSum([banglore[f] * proj_vars[f] for f in project_list]) <= 3

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.

I've been looking at porting Tock OS on to the pulp platform and mostly reading through the documentation. I'm fairly new to this whole thing, so I have few questions. According to the TockOS porting guide, I need to define the following in the linker file

Quote: For most developers, it should
 * be sufficient to define {ROM/PROG/RAM}_{ORIGIN/LENGTH} (6 variables, the start and length for each),
 * MPU_MIN_ALIGN (the minimum alignment granularity supported by the MPU) and PAGE_SIZE (the size of a flash page).
 * If undefined, PAGE_SIZE uses the default value of 512 bytes.
