Honored ContributorDownload image ok, but boot fail
Hi Guys,
I need help... maybe someone have passed for this trouble. I try to run Linux on Nios II, obviously. My project is based on DE2_NET. Now I used a CYCLONE II EP2C8F256C8 in a custom board. First, I build the project for uCLinux and ran with sucess. After that, I add the TCMs in the SOPC and uClinux ran with success. So, after the system was validated, I went to LINUX with MMU. After some days, I can to program/download the image in a Flash with sucess. But the Linux don't boot. The stdout is a jtag_uart. When I run the “nios2-terminal”, nothing happen. Don't show error or some information... the terminal was blank, like this: [NiosII EDS]$ nios2-terminal nios2-terminal: connected to hardware target using JTAG UART on cable nios2-terminal: "USB-Blaster [USB-0]", device 1, instance 0 nios2-terminal: (Use the IDE stop button or Ctrl-C to terminate) Well, the Address Map is this: cpu.jtag_debug_module 0x08000000 - 0x080007fftimer_0 0x08400000 - 0x0840001f

Altera_ForumMore one question:
Wich addresses should I put in Linux Kernel Configuration in these options: (0x????????) offset address for uimage.flash(0x????????) link address offset for booting Thanks
- Altera_Forum
did you checked your cpu reset vector ? does it point on your EPCS at the correct address ?
- Altera_Forum
Normaly you have to boot on your SDRAM so you don't need to change your kernel configuration...
- Altera_Forum--- Quote Start --- did you checked your cpu reset vector ? does it point on your EPCS at the correct address ? --- Quote End --- The Reset Vector point to 0x00000000 (ext_flash + offset = 0x0) When I download uCLinux in this SOPC (without MMU) the system ran perfectly. In this case, the Reset vector point to same address. I'll try change for epcs... Thanks

If I download the Linux image via "nios2-download" command line, the result is:

I think you might be mixed up in the flash usage. You programmed the sof and zImage to epcs flash. So you should set reset vector to epcs controller in sopc builder.
ext_flash means cfi flash, in your address map , it is only 1MB? If you want reset vector to ext_flash, you should program the zImage to ext_flash. - hippo - Altera_Forum
Thanks Actris and Hippo!!!
I change the reset vector to epcs_controller. I program the image into Flash memory and run the nios2-terminal. Now, the boot freeze after some initializations... This is a good new if we compare with old result. :cool: This is the new Results for "zImage.initramfs.gz": [NiosII EDS]$ nios2-terminal nios2-terminal: connected to hardware target using JTAG UART on cable nios2-terminal: "USB-Blaster [USB-0]", device 1, instance 0 nios2-terminal: (Use the IDE stop button or Ctrl-C to terminate) Uncompressing Linux...

I see you have 16MB, not 8MB. Please config "boot link offset" to 0xa00000. That means zImage will start from top 5MB, and won't collide with kernel.
- Hippo - Altera_Forum
I change to 0x00a00000. The result was the same.
In the "niosii fpga configuration (custom_fpga)" screen, Wich the value should I put on "(0x______) offset address for uImage.flash"? Now the values are: [*] hw mul support[ ] hw mulx support
[ ] hw div support
(0x1c80000) offset for uimage.flash
[*] passed kernel command line from u-boot
(0x00a00000) link address offset for booting
[ ] support for dma ...
[ ] gpio interface
<> enable niosii pio driver
[*] activate early kernel debugging
... Thanks a lot, Hippo!
- Altera_Forum
(0x00a00000) link address offset for booting is correct.
Please skip the flash programmer at the moment. Please use nios2-download during the test. cd uClinux-dist make menuconfig make nios2-configure-sof your_system.sof nios2-download -g images/zImage - Hippo
