hi,everyone! i want to sent the file (for exmple a.dat)of host through the jtag uart to the sdram,which in up3 board.i have get some exmples as for the message sent by uart to host,not the file. but,how can i to cope with it?can someone give the source code for it?thank you !

Hi liannunu, > i want to sent the file (for exmple a.dat)of host through the jtag uart to the sdram This was possible with nios-console (Nios-32) via the stdio window. But I don&#39;t think it&#39;s available for Nios II (nios2-console). Regardless, you can still use the nios2-console load command to load a bin, hex, or srec file from your host machine to Nios II memory. E.g.: load file a.dat to address 0x1000: 1> load bin 0x1000 a.dat This may not be quite what you want, but it may give you some of the capability you need. Regards, --Scott

If you&#39;re using >=5.0, you can use the hostfs filing system. The limitation being that it only functions when in Debug mode. It&#39;s now a part of the rozipfs example software template. - slacker

thank you for your reply.however,i still have some questions about it --- Quote Start --- E.g.: load file a.dat to address 0x1000: 1> load bin 0x1000 a.dat and do i need input the the path and the a.dat .if i want to seng several files for example 3,what should i do?i guess that to make the command line three times?meanwhile,i want to send these files to sdram in up3,but the command line have nothing about the destination?such as sdram,flash or fpga? in the reply of slacker&#39;s,whether the hostfs filing system is the" /mnt/rozipfs"?if so ,i want to send these files to sdram in up3, can the the hostfs filing system implement sending three files at a time?i use the nios 1.1now,i only to see the altera zip read only file system,does ti result from the version 1.1? thank you all the same!

hostfs is not supported in v1.1. You would need, at least, v5.0. I&#39;d recommend upgrading anyway... Once you&#39;ve done this, you&#39;ll see that the example now contains a mount point of "/mnt/hostfs". Best Regards, - slacker

thank your reply! i have met a new question on the example now contains a mount point of "/mnt/hostfs" tonight,while i run as the nois hardware ,and the properties of the syslib in which i set all the auto-generated linker script to sdram,at last the console reported "verified ok leaving target processor paused." in the side of the console ,the only first result of the argument of printf() can be executed and paused . may i get some information about it?i guess that is possible to have some problems on the quartus project ? thank you all the same!

Or a combination of the two...

cat <filename> | nios2-terminal >& terminal.log

You could write more elaborate scripts/code using pipes going into and out of nios2-terminal.

The above is OK if batch style IO is acceptable.
Do you know if it is possible to use the IO redirection tricks above to allow an existing windows terminal app to talk (tx and rx) over the jtag uart?

The all the redirection examples I have seen, the data flow is one-way only.
I am thinking that you would need something like a virtual serial port.

Hi
I record a tutorial on how to mount text file using NIOS II Processor and hostfs feature which enables us to mount files (such as text file) and perform read and write operation on that file
