Hit this error also.

It seems that there is some file path problems between Windows and linux subsystem.

Found out a workaround by making a copy of bootloader_cfi.srec to eclipse workspace directory and making modification to BOOT_LOADER_CFI in bsp mem_init.mk file.

#BOOT_LOADER_CFI ?= $(BOOT_LOADER_PATH)/boot_loader_cfi.srec
BOOT_LOADER_CFI ?= ../boot_loader_cfi.srec

(Nios project and bsp are directly under workspace)

edit: --

alt-file-convert.exe seems to want a windows path for --boot option (in windows machines), as mem_init.mk BOOT_LOADER_CFI modification to windows path removes error:

BOOT_LOADER_CFI ?= "'C:\intelFPGA\19.1\nios2eds\components\altera_nios2\boot_loader_cfi.srec'"

---

With this modification the mem_init_generate runs and there is a flash hex file which content seems to be correct (real world booting not tested yet)

    Hi @ppauli ,

    many thanks for this solution!

    I am facing this issue with Quartus Prime Pro 19.3 as well. Your fix seems to work. I did not verified on a target, yet.

    Is this issue fixed in newer Versions of Quartus Prime? Is there an official solution provided by Intel?

    BR, Dirk
