FlashProgrammer has some problem!

[Altera_Forum]

Hi, everybody 

 I'm newbie for niosII uClinux. I want NiosII boot from CFI Flash but I open NIOSII Command Shell can't find "cd arch/nios2nommu/boot" dir. Is my NIOSII Command shell has some problem?  Need you help!  thank you for your give me some suggest!  NiosQ

The wiki page is updated. 

You have to build uClinux with uClinux-dist and test the image from sdram, before trying flash programmer.

The wiki page is changed. There is no need to "cd arch/nios2nommu/boot" now. 

If you have tried from sdram, you should know where is the zImage. ~/uClinux-dist/images.  If you work on Linux, open a normal terminal shell.  If you work on Windows, you have to copy the zImage to a temp window dir. And work in that dir.

That&#39;s right. You cannot use Linux shell to program jtag on coLinux under windows. You can only use Linux shell to program jtag on Native Linux.

Dear,hippo 

thanks you for your reply.  http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/biggrin.gif

Hi,hippo 

I used DE2 board. Can I programmer Hardware.sof and zImage noto CFI Flash? Or hardware.sof need programmer to EPCS flash?  regards NiosQ

[Altera_Forum]

It is hardware wired on DE2 board. 

The sof for fpga must go EPCS. The zImge can go eithter EPCS or CFI flash. But the zImage might be too large for EPCS.

[Altera_Forum]

The zImage is loaded to sdram by a altera supplied boot loader. So there is nothing to do with kernel config. 

 Since you want to boot from cfi flash, you must make sure the Nios2 reset vector in SOPC builder pointed to cfi flash. Though it should be the default.

If you jtag uart, then you must have nios2 terminal connected. 

NOTE, you can use JTAG UART console during development. But if you don&#39;t connect a nios2-terminal, the program will hang. So you shouldn&#39;t use JTAG UART console for standalone or production. You must disable JTAG UARTconsole then. You still need a console device after disabling JTAG UART console, otherwise the init task will exit and panic. You may use Nios serial uart as console, or use Virtual Terminal (actually it can be dummy) as console.  If you use serial uart, you use RS232 cable with hyper-terminal on Window, or minicom and kermit on Linux.

[Altera_Forum]

Did you test the new sof with serial uart and uClinux image using jtag download? 

You should make them work before flash programming.  You sould not use nios2-terminal in this case, use RS232 cable and a terminal emulater, such as Hyper-terminal on Windows, or minicom on Linux.

[Altera_Forum]

The reset address in SOPC builder has nothing to do with uclinux. 

If you want to boot uclinux from epcs, select epcs as reset address. If you want to boot from cfi flash, select cfi flash as reset address.  First, you should make RS232 work using jtag download.
