NIOS application build fail

So,

Rolling back to 18.1 (Cygwin based) version and importing the project works ok. Anyone else seeing this issue with v20?

"I have recently created a NIOS II application for UART which has built and run correctly up until today. I have not made any changes other than to rebuild the release/debug app."

Hi @Boondoggler , I'm interesting to your NIOS Application for UART , if possible, can you share it here for us for reference. 3Tanks

Hi Boon,

Can you try to find a new computer to install or remove NiosII EDS and reinstall it?

You may try below manually.

1. install WSL for windows

i. https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/nios2/n2sw_nii5v2gen2.pdf (chapter 2.1)

Note: Windows 10 build version 16215.0 or higher is the recommended operating system version.

ii. After installation has successfully completed, launch Ubuntu 18.04.

iii. Install additional distro packages required for Nios II EDS using the following commands:

a. sudo apt install wsl

b. sudo apt install doc2unix

c. sudo apt install make

before"sudo apt install wsl"

run:

sudo apt-get update

2. install nios2 eclipse folder

Hi, Boon

Have you tried below workarounds ?

Hi, Boon

Can you try below workarounds ?

#1

Open a NIOS2 command shell

try and make an NIOS2 application

You get the following error: nios2-elf-gcc.exe: error: CreateProcess: No such file or directory

To resolve this you need run the following command prior to calling make, "export WSLENV=PATH/l:${WSLENV}"

#2

With the above fix you can compile all the files but the link fails:

nios2-elf-g++.exe: error: missing argument to '-msys-lib='

To resolve this you need to modify the application Makefile and change the following line:

APP_LDFLAGS += -msys-lib=$(call adjust-path-mixed,$(SYS_LIB)) to APP_LDFLAGS += -msys-lib=$(SYS_LIB)

In adjust-path-mixed should not be used in this case as SYS_LIB is a name of a library not a PATH to the library

#3

The final problem is that from eclipse debugging fails with the following error:

wslpath: /mnt/f/main_clean/Software/omni_ip/projects/wfm_ss/example/wfm/wfm_app/wfm.elf.srec: No such file or directory

wslpath: /mnt/f/main_clean/Software/omni_ip/projects/wfm_ss/example/wfm/wfm_app/wfm.elf.srec: No such file or directory

Using cable "USB-BlasterII [USB-1]", device 1, instance 0x01

Pausing target processor: OK

Restarting target processor

rm: cannot remove '/mnt/f/main_clean/Software/omni_ip/projects/wfm_ss/example/wfm/wfm_app/wfm.elf.srec': No such file or directory

To resolve this problem the Application Makefile must be modified again with the following change:

BUILD_PRE_PROCESS := to BUILD_PRE_PROCESS := touch $(ELF).srec
