IDE Problems

[Altera_Forum]

Hello, 

 This is a repost of a thread on the UC forum. I wanted to post it here also on the software forum. My problem is below this first post.  Thanks,  -Baycool   *********************************************************  This is a custom board. I have taken everything out except for the Flash and SDRAM. It is actually a fairly simple system, flash, sdram, and an ethernet port. I don't use tightly_coupled_memory (have not familiarized myself with it yet), and my data cache line size is 4 Bytes, exception pointer is set to SDRAM.  I am out of ideas. I also can not load the kernel into RAM from the IDE, I'm forced to burn the Flash each time I make a change. I get the following message from the IDE console. Do I have a JTAG problem? I'm using a USB Blaster "Rev B".  Downloading 08000000 ( 0%) Downloading 08010000 ( 6%) Downloading 08020000 (12%) Downloading 08030000 (18%) Downloading 08040000 (25%)assertion "m_state == STATE_DEBUG" failed: file "nios2 debug.cpp", line 1695 Signal 6    Here is a copy of what I get when I launch the nios2-terminal. Most of the time I'm unable to log into the system, I usually get "Login incorrect." When I am able to log in, I usually get kicked out fairly shortly, and the system goes back to the login prompt.   uClinux/Nios II Altera Nios II support © 2004 Microtronix Datacom Ltd. Built 1 zonelists Kernel command line: root=/dev/mtdblock0 ro PID hash table entries: 1024 (order: 10, 16384 bytes) Dentry cache hash table entries: 32768 (order: 5, 131072 bytes) Inode-cache hash table entries: 16384 (order: 4, 65536 bytes) Memory available: 128640k/131072k RAM, 0k/0k ROM (857k kernel code, 203k data) Mount-cache hash table entries: 512 (order: 0, 4096 bytes) Linux NoNET1.0 for Linux 2.6 Serial: JTAG UART driver $Revision: 1.4 $ ttyJ0 at MMIO 0x80000860 (irq = 2) is a jtag_uart io scheduler noop registered io scheduler anticipatory registered io scheduler deadline registered io scheduler cfq registered RAMDISK driver initialized: 16 RAM disks of 4096K size 1024 blocksize Altera NDK flash (AMD): Found 1 x8 devices at 0x0 in 8-bit bank Amd/Fujitsu Extended Query Table at 0x0040 Altera NDK flash (AMD): CFI does not contain boot bank location.

I also get the mysterious error:  assertion "m_state == STATE_DEBUG" failed file "nios2debug.cpp", line 1695 signal 6  What does this message mean? I just opened an SR with Altera, but have been stuck with this for a couple of weeks now....  My conditions are as follows:  I get this error just by reversing the order of how I open my tools. If I open a shell to load my hardware before opening IDE I get the error. If I open IDE before opening my SDK shell I DO NOT get error. The result is reproducible with some of my boards. Other boards will hang with the message:   nios2-terminal: (Use the IDE stop button or Ctrl-C to terminate)  or not respond to further commands.  I am in a jam because my boards have been manufactured and assembled and are ready for production , and now this error shows up.  -Baycool  I am using Quartus 5.0 and Nios II 5.0 with a Full License for both

Hello, 

 I just wanted to share with the forum, that I believe my error below:  assertion "m_state == STATE_DEBUG" failed file "nios2debug.cpp", line 1695 signal 6  was caused by faulty ssram. I do have a custom board that still suffers with a Byteblaster like circuit, but    So, in case any one has ruled out their JTAG connection or noise problems, do a robust on-chip test of your memory before doing a SW download.  Thanks "slacker" for your assistance...  -baycool
