[Install] 2. Prepare Drivers

Hello everyone,

I am really interested in trying your platform for resonator characterization, but unfortunately I am having some trouble with the installation on the RedPitaya (14 bit version).

After running sudo make install_nfsdir (https://github.com/oscimp/oscimpDigital/wiki/2Prepare#drivers)
I made sure to follow every instruction, including adding Path and sourcing the variables.

bernardo@bernardo-ThinkPad-X230:~/oscimpDigital/linux_driver$ sudo make install_nfsdir make -C add_const_core install; make -C axi_to_dac_core install; make -C data_dma_direct_core install; make -C data_to_ram_core install; make -C edfb_core install; make -C fft_core install; make -C fir_core install; make -C fpgagen_core install; make -C nco_counter_core install; make -C pidv3_axi_core install; make -C redpitaya_converters_12_core install; make -C switch_core install; make[1]: Entering directory '/home/bernardo/oscimpDigital/linux_driver/add_const_core' Makefile:2: /Makefile.inc: No such file or directory make[1]: *** No rule to make target '/Makefile.inc'.

Stop. make[1]: Leaving directory '/home/bernardo/oscimpDigital/linux_driver/switch_core' Makefile:7: recipe for target 'install_nfsdir' failed make: *** [install_nfsdir] Error 2

Running only make install_nfsdir yields:

I should add some considerations:
The buildroot-2020.11.1 is untouched besides the instructions given in the Wiki.
The file Makefile.inc is indeed in the parent directory.

Anything else that would help this debugging I can happily provide.

Thank you very much for the help!

Customized IP Guidelines

Hello everyone.

I am a user of the OscimpDigital framework and I would like to start by thanking you guys all the good work.

I use a 14b RedPitaya to do some signal processing on my sensors and wanted to implement a biquad structured IIR lpf with coefficients that could be accessed externally by the user and injected through the add_const IP. There would be no need to add these to the libOscimpDig libraries since I could change the coefficients in such a simple way like in the FIR IP.

I saw an (unfinished?) implementation of the IIR lpf (https://github.com/oscimp/fpga_ip/blob/master/iir_lpf_complex/hdl/iir_lpf_complex.vhd). I have tried to adapt this script (annexed) for my implementation, but when I tried connecting it to the other IPs the connections did not match.

library ieee;
use ieee.std_logic_1164.all;
use ieee.numeric_std.all;

entity iir_lpf_complex is 
	generic (
		DATA_WIDTH : natural := 16
	);

	);
end entity;

I used Vivado's IP Packager.

Are there guidelines to make customized IP compatible with the OscimpDigital library? Or could you point me in a direction where I could make this specific source compatible?

Thank you!

NFS mount - connection timed out

Hello once again.

I am encountering a problem regarding mounting the nfs folder on the red pitaya.

I have tried debugging it, but with no success.

1. I am able to ping the RP from my host computer.

bernardo@bernardo-ThinkPad-X230:~/oscimpDigital$ ping 192.168.0.10
PING 192.168.0.10 (192.168.0.10) 56(84) bytes of data.
64 bytes from 192.168.0.10: icmp_seq=1 ttl=64 time=0.225 ms

and vice-versa:

redpitaya> ping 192.168.0.1
PING 192.168.0.1 (192.168.0.1): 56 data bytes
64 bytes from 192.168.0.1: seq=0 ttl=64 time=0.402 ms

All necessary files are sourced:
source redpitaya/sourceme.ggm
source oscimpDigital/settings.sh
source /tools/Xilinx/Vivado/2019.2/settings64.sh
export PATH=/buildroot-2020.11.1/output/host/usr/bin:$PATH

are executed everytime I open a new terminal

My exports file in RP:

/nfs *(rw,no_root_squash,sync,no_subtree_check)

My fstab file (I have tried both the existing line and the one present in the wiki, chapter 2. Prepare):

GNU nano 5.2 New Buffer Modified

/dev/root / ext2 rw,noauto 0 1

#192.168.0.1:/nfs /usr/local nfs defaults,noauto,nolock 0 0

I have nfs-kernel-server and nfs-common installed and updated. I have uninstalled and re-installed to see if that would fix the situation but it did not. I have checked the ports used by nfs (followed https://serverfault.com/questions/377170/which-ports-do-i-need-to-open-in-the-firewall-to-use-nfs) and I disabled the firewall for those ports.

When executing the last command on Chapter 2, I get a connection timed out error in the red pitaya.

redpitaya> mount /usr/local
mount: mounting 192.168.0.1:/nfs/redpitaya on /usr/local failed: Connection timed out

Is there a log that could hint me what could be originating this error?

Could the cause be the location of the nfs folder and the path interpretation depending if you are root or not when doing the last steps of Chapter 2 on the host computer?

I have tried doing the final steps both at the oscimpDigital folder and using sudo su and following the steps from there.
In the last case, the nfs folder will be created in the SSD where the host computer system folders are. Here if I am not mistaken is where I think ~ is interpreted differently.
The combination of the settings.sh file, the export file and the fstab file not matching is something that I would like to take out of the way before assuming it is a networking problem. What is the default location of the NFS folder in a working environment?
