Error: s0: Cannot find sequencer/sequencer.elf

Hello,

After a recent Windows 10 update we are unable to regenerate a Platform Designer system. First errors printed are:

Same happens with versions 18.1.1 / 19.1.0 / 20.1.1

Is there a patch / workaround?

Update: we were able to regenerate the Platform Designer system with version 20.1.1 after installing WSL (Windows Subsystem for Linux)  version 1 according to:

How to install the Windows* Subsystem for Linux* (WSL) on Windows* OS? (intel.com)

Install Windows Subsystem for Linux (WSL) on Windows 10 | Microsoft Docs

Any ideas on how to fix the issue for versions 18.1.1 / 19.1.0 ?

Sergio

Hello!

Same issue with fresh installed Quartus Prime Lite 20.1.1 on Windows 10 Pro (with latest updates).

returns: 4.4.0-19041-Microsoft

Still unable to generate DDR3 UniPHY controller due to error:

Hi,

we are seeing the exact same issue as sergvdm.

Beside from ubuntu 18.04 and wsl1 we also tried ubuntu 20.04 with wsl2 but no luck either.

It's failing to compile the sequencer.elf because of:

Error: s0: Compiling alt_dcache_flush_all.c...
Error: s0: nios2-elf-gcc.exe -xc -MP -MMD -c -I./HAL/inc -I. -I./drivers/inc -pipe -D__hal__ -DALT_NO_C_PLUS_PLUS -DALT_NO_CLEAN_EXIT -D'exit(a)=_exit(a)' -DALT_NO_EXIT -DALT_USE_DIRECT_DRIVERS -DALT_NO_INSTRUCTION_EMULATION -DALT_USE_SMALL_DRIVERS -DSMALL_C_LIB -DALT_SINGLE_THREADED -Os -g -Wall -mno-hw-div -mno-hw-mul -mno-hw-mulx -mgpopt=global -o obj/HAL/src/alt_dcache_flush_all.o HAL/src/alt_dcache_flush_all.c
Error: s0: Makefile:539: recipe for target 'obj/HAL/src/alt_dcache_flush_all.o' failed

I want to look at the generated code for the sequencer, but sadly the temp folders get deleted after failing.

WSL is now mandatory, right?

So why do you still  call windows binaries (nios2-elf-gcc.exe) instead of linux elfs in the wsl?

Please help us.

I can't stay much longer on 18.01 and disabled wsl.
