I am novice to linux but I am working on a project using the bf561 and uClinux. I have a couple of questions if someone can please help or guide me in the right direction, it would be much appreciated.

you need to actually post a question to get an answer

the documentation wiki is here:

I was having trouble coping and paste sorry.

1) I currently have the default uClinux image for bf561-EZKIT running on the board through the terminal. My question is how can I obtain the configuration file of the image provided on the website. The reason is because when I extracted the kernel linux-2.6.xx from the uClinux distribution source file also from the current release page, I tried compiling the kernel in colinux using the Debian rootfs. I was successful but after going through the kernel configuration using menuconfig my image was only about 0.6Mb and also didn't boot on the bf561. I am new to this, as I stated, so I really don't know what configuration options to set, to get my image to boot. I believe if I can get the config file then it would be easier to tweek around with and add features as needed because time is of the essence right now.

I can compile the kernel successfully but I am assuming there are now libraries or maybe even a file system on the kernel. How do I add these things to compile them in the kernel???

Thanks in advance and many options are welcome.

2) In our project we are using the bf561 and it has 1 UART. We are using this along with the serial port to talk to the terminal. Please bear with the term usage. Anyway, we need to set up more than one terminal and I would like to know is it possible to set the UART up some kind of way vitrually I guess, to supply more that multiple terminals running at the same time even though there is one serial port. Is this a kernel configuration option??

you dont extract any subdir from the source tree. you need the entire uclinux-dist tree. the default images posted use the default config files for that target.

docs.blackfin.uclinux.org/doku.php?id=target_selection

you can either run ppp over the UART and use the device as a network connection (so you can telnet/rcp in parallel as much as you want), or you can use the SPORT/UART device driver which emulates a UART device with a SPORT. although the second option requires you to make some custom hardware.

Well I am a beginner to this, is it possible to explain how run the ppp over the UART or give in additional details on using it?? Thanks

again, we have a wiki with a search function. please use it. searching for "ppp" easily finds the answer:

docs.blackfin.uclinux.org/doku.php?id=uclinux-dist:ppp
