glibc 2.2.1
linux 2.4.12
We want to update to a 2.6 kernel, recent build tools, and saner system
libraries. Although, it seems that the JMR 3927 is still technically
supported, I have not found any info on whether anybody is still running
Linux on it and what combination of software they are using. Any idea?
Is there a combination of software versions that are known to work on this
hardware?
I have used crosstool 0.43 to build:
binutils 2.15
gcc 3.4.5
glibc 2.3.6
http://www.linux-mips.org/wiki/Toolchains recommends binutils 2.16.1 and
gcc 3.4.4, but I believe your choice is also ok for 32-bit systems.
I will try that combination also.
Hard to tell from so little information, it would help to see the whole
boot log.

I wish that there were more of a boot log of which to speak. The
following is a complete boot log:
Serial Number = WAC6200032
MAC Address 1= 00:0D:5D:00:eb:6f
Kernel Image Length = 0x695000, CRC = 0xd2ee6a23
Loading Linux ......
Downloading from ethernet, ^C to abort and restart pmonitor
sendRRQ vmlinux.bin

Checking CRC on downloaded RAM image

CRC Check passed
Image Started At Address 0x80020000.
Image Length = 3424394 (0x34408a).
Exception! EPC=80056eb4 CAUSE=30000008(TLBL)
80056eb4 8ce4000c lw a0,12(a3) # 0xc
All messages before the exception are from PMON. I am booting via TFTP.
I also tried writing the kernel to flash and booting from that, but that
fails identically.
I checked the other serial port on the device, but it is not showing any
kernel messages either. The normal boot console is ttyS1. I tried
setting the kernel parameters and the default parameters (from the
kernel build config) to "console=ttyS1", but that made no difference.
Regardless, I would think that the kernel knows where to send messages
because I am seeing the exception dump on ttyS1.
Further, the exception gets printed immediately after "Image Length =
3424394 (0x34408a)." The exception happens so soon that I doubt that the
kernel does very much beforehand.
Thanks
