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

the sdram have 8mbyte (pn: is42s16800d).
the flash memory have 8mbyte (pn: mp25p64).
the pll on the sopc builder is 100mhz for all peripherals. This is my script for download/program: ------------------------------------------------------------------------------------------------- nios2-configure-sof mylinux_top.sof
