Hi,
I followed the readme file of pulpissimo  for building an RTL simulation platform. After the following steps

Hello everyone,
Could someone please help me bypass the FLL logic ? I want to use an external clock for my design.
At the moment, I have removed the gf22_FLL instances and tried to connect soc_clk and per_clk directly to ref_clk.
Could anyone please share their experience of bypassing the FLL ? How did you handle the rest of the logic present in soc_clk_rst_gen.sv file ?
With this, I get error captured in the attachment. 

Cheers

I am trying to synthesize Pulpissimo with Vivado 2019.2 for nexys A7-100. I get the following errors:

We are currently evaluating the RI5CY core for our project and the possibility of adding custom instructions is important for us. Some other cores (Sifive E31, Vexriscv) have simple and documented ways to do this, but I couldn't find the information about RI5CY. HWPEs are great but we may need a true custom instruction support for our needs.

Hello,

while looking at the pulp-rt-examples I found the uart examples and I was wondering if it's possible to print the contents of the buffer to minicom using the rt_uart_write function.
I have already tested the hello example on ZedBoard and the printf works just fine with minicom.
Now I was wondering if it's possible to write the same Hello! to minicom using the rt_uart_write function.
If I run the send example I don't get any output on minicom or in RTL simulation.
Same if I put a string in the buffer instead of the loop that is used in the example.
Shouldn't it be possible to get something on minicom with this method somehow?
I also played around with the RTS and CTS signals as i didn't want to have them float, even tho it worked with the normal hello example, but it didn't help with the above method.
Does anyone have any experience with this?

Edit: I managed to make it work. It was an issue in the code of the app I tried to run.

Thank you,
LPLA

Hi,
I am trying to compile a simple code which has global arrays. I have initialized all the global arrays to make sure the compiler does not generate the code to initialize them to 0. However, I am still getting these "memset" calls in the _start section of the assembly.

Hello! I checked existing threads but did not find a solution for my problem. 
I've already installed simple runtime and executed expample "hello" successfully. 
While I was installing SDK, I had some problems. I just follow the steps in 
GitHub and run the "make build-pulp-sdk" and some errors just came out.


Environment:
CentOS-7
gcc 4.8.3
python 3.6.8

Following is some of the configuration in my ".bashrc". 
export PATH=$PATH:$HOME/mylib/v1.0.16-pulp-riscv-gcc-centos-7/:/tools/linux/mentor/modelsim/10.6a/modeltech/

I wrote this "source_pulp.sh" and source it once before I start building SDK.
PULP_HOME=$HOME/pulpissimo
export PULP_RISCV_GCC_TOOLCHAIN=$HOME/mylib/v1.0.16-pulp-riscv-gcc-centos-7
export VSIM_PATH=$PULP_HOME/sim
export CPLUS_INCLUDE_PATH=/usr/local/include/ImageMagick-6
source $PULP_HOME/pulp-runtime/configs/pulpissimo.sh
source $PULP_HOME/setup/vsim.sh
source $PULP_HOME/pulp-sdk/configs/pulpissimo.sh
source $PULP_HOME/pulp-sdk/configs/platform-rtl.sh


1. I've already installed configparser at /usr/local/lib/python3.6/site-packages.
   But "No module named configparser" shows up from time to time. Should I install 
   configparser with another method or just run several times to ignore the error?

2. I've installed ImageMagick at /usr/local/include. When I use ImageMagick-7 as
   the library, this error occurs.

   But after I choose ImageMagick-6 as the library, this error occurs.

I would like to know whether I installed ImageMagick correctly. If there's 
anything needed to help me deal with these problems, please let me know! 
Thanks a lot!

Hi,

I would like to run small home-made algorithms of languages other than c on the HERO platform.
Is offloading to bigPULP only possible with OpenMP or are other APIs implemented?

Thanks.

Hi ,
I am trying  C to hex conversion for a simple (addition) program. My disassembly code is as follows:

Hello,

yesterday I had an error while executing the ./update-ips command.
