quartus/Nios 13.1 make mem_init_generate error 255

[Altera_Forum]

I have a project created in nios 13.1 that I am trying to create a hex file for. 

 From C:\altera\13.1\nios2eds I load the Nios II Command Shell.bat which loads the command shell   Next i navigate to the project app directory and run: make mem_init_generate  after the [BSP build complete] it tries to run bash -c 'elf2hex etc...' and gives an error  make: *** [mem_init/file_RAM_on_chip.hex] Error 255  When I do a mem_init_generate within nios 13.1 everything works.  Also if i run the "make mem_init_generate" with the "C:\altera\13.0sp1\nios2eds" Nios 13.0 II Command Shell everything works (it is able to generate the hex file)   what is causing the 13.1 command shell not to work properly?  right now i have to install both 13.0sp1and 13.1 to get it to work http://www.alteraforum.com/forum//images/icons/icon8.png

Ran into the same problem on linux. My normal shell environment was missing the QUARTUS_ROOTDIR variable. Setting it to C:\altera\13.1\quartus\quartus should get you going.

I tried to set the QUARTUS_ROOTDIR via the "Nios II Command Shell.bat" file it gave the error 

 C:\altera\13.1\nios2eds>"Nios II Command Shell.bat" QUARTUS_ROOTDIR_OVERRIDE="C: \altera\13.1\quartus\quartus" C:/altera/13.1/nios2eds/nios2_command_shell.sh: line 175: exec: QUARTUS_ROOTDIR_ OVERRIDE=C:\altera\13.1\quartus\quartus: not found  I checked the folder and saw that it does not have a quartus folder within C:\altera\13.1\quartus  --------------------------------------------------------------------------- Update,   By deleting bin folder contents from C:\altera\13.1\nios2eds\bin and replacing it with the contents found in C:\altera\13.0sp1\nios2eds\bin I was able to get everything to work.

Turns out this is a problem in 13.1 and can be fixed by adding this line to the .sh file export quartus_bindir=${quartus_rootdir}/bin
