Rocketboards Nios II Linux - Error adding SCSI and some other questions

I've got a previous MMU design from the uClinux-dist that I know works. I have a *.dts and my *.sof that I'm not trying to get going on the Rocketboards Nios II linux-socfpga. 

 

It runs on the DE2-115 Terasic board. I have a daughter card with a compact flash adapter.  

 

So in the kernel configuration I also enable SCSI disk support and Serial ATA Generic platform device PATA support. 

 

When I do a "make vmImage" I get the following error: 

 

************************************************** **************************8 

[user1@localhost linux-socfpga]$ make vmImage 

CHK include/config/kernel.release 

CHK include/generated/uapi/linux/version.h

make[2]: *** [drivers/scsi/scsi_lib.o] Error 1 

make[1]: *** [drivers/scsi] Error 2 

make: *** [drivers] Error 2 

[user1@localhost linux-socfpga]$  

 

************************************************** **************** 

 

Can anyone help tell me what's the problem? 

Does this new Nios II Linux support what I need to do? 

Thanks in Advance 

 

Oh - if I remove the SCSI I can't boot either -- I get: 

 

Linux version 3.14.0-00598-g8adb74d (user1@localhost.localdomain) (gcc version 4.7.3 (Sourcery CodeBench Lite 2013.05-43) )# 7 Wed May 7 13:20:41 CDT 2014 

bootconsole [early0] enabled 

early_console initialized at 0xe9004040 

BUG: failure at mm/bootmem.c:378/mark_bootmem()! 

Kernel panic - not syncing: BUG! 

 

Any help would be greatly appreciated.  

I'm assuming that the Rocket boards Nios II linux is what I should use now for Altera nios2? If this isn't true then please let me know. 

Also, is this all MMU or can I do a non-MMU project by just not having it in the *.dts file?

O.K. so I found the define in ../include/asm-generic/pci.h and I added that include to the scsi-lib.c file. I have a vmImage but don't have the board right now. 

 

I'd still like some clarification of the status of this Nios II Linux release if anyone can help out with that. 

 

Thanks.

The Nios II Linux is maintained by Altera, and is based on MMU. 

UcLinux-dist is not being maintained by anyone afaik.

I also think that no one is maintaining the uClinux-distri, but please don't blame every error on their maintenance. 

And also I think that Altera is passing a whole NiosII Linux thing onto other companies and doing nothing by themselves.
