Your PCB Is in the Mail & A Question

Patrick,

My wonderful wife Sherri sent your "home grown" development daughterboard 
via US Priority Mail today.

Question...

I need help form an MTD driver expert...

You put this on the Wiki...

   Flash ROM map

   0x00400000:   Begin flash ROM
   0x00400000:   boot loader
   0x0040C000:   Begin OS writable flash segment (16k)
   0x0040FFFF:   End OS writable flash segment
   0x00410000:   compressed kernel image
   0x004B0000:   start of ROM disk image (Taken from stock boot logs)
   0x005FFFFF:   end of flash ROM

How did you determine the location of the "OS writable flash segment"?  I 
believe this is the device /dev/mtdc0 and /dev/mtdc1.  My build of the 
kernal always fails to open this device.  (See the end of this email for 
my /dev/console log on boot.)

I've got my kernel build booting with a few less problems, including what 
looks like some function in the modem chip.  I can get it to go off-hook, 
and hang up, but not dial.  I managed to get the kernel to load an 
important Actiontec "propriatary module" by adding some EXPORTs to the 
kernel for two of the entry points the module was missing.  The module is 
"/lib/modules/cnxtserial_buildin.o".  This clearly sets up the modem 
somehow because now I have the modem UART device /dev/ttyS2 active.

However, the only thing I can't seem to get to work is the MTD device that 
they are using to "configure" the PPP connection.  This is keeping the 
device /dev/ppp from running.

There are a large number of configuration options for MTD drivers.  Have 
you (or anyone else) got any clue as to how Actiontec built theirs?

I'm clueless in this area.  The error message...

   Can't allocate major number 31 for Memory Technology Devices.

...is telling.  I don't know what I'm doing! :-)

Based on your "memory map", it looks like the "character mode" MTD device 
that they are using uses a chunk of flash in the middle of flash memory. 
How does one specify something like this?

Bottom line...does anyone have any ideas on how to "config" this device?

BTW: I still have to restore "boot-ldr.bin" each time I boot my kernel in 
order to get my Actiontec box to reboot.  I can login and do whatever I 
want after the *first* reboot, but when it's time to re-boot, the 
"bootstrap" is gone!  What's up with that!?

Best regards,

Bruce
