19 years agoProblem starting up linux on Nios II Cyclone
Hi everybody, despite my earlier post I now have a big problem with trying to start linux. The kernel and filesystem compile ok, with a few warnings on the way. What I get when I try to log on through Nios II SDK shell is:
$ nios2-terminal
nios2-terminal: connected to hardware target using JTAG UART on cable
nios2-terminal: "USB-Blaster ", device 1, instance 0

$ Those "init: exec failed" messages keep coming and coming unless I terminate the connection with ctrl-C. As you may notice, it complains about "code brokenness". The linux is the same linux I got from this website, and the .ptf and .sof I'm using are from the Microtronix Eth -USB Expansion kits CD. I used the Quick Start Guide as a reference in setting up the kernel and the filesystem, so nothing special was done. Anyone have any idea what's going on?
