Re: [uClinux-dev] Shared library issues on m68knommu and gcc 4.1.1

[paul_dale]

I missed your initial message.  I did the m68k shared library work so I ought 
to understand this, although it was quite a few years ago now and memory 
fades...

I think so, at least what you've said seemed to make sense and matches what I 
remember.  This stuff is very rusty to me, we've not used ColdFire parts for a 
number of years :-(  Actually, lots of years.


> Is this the right list to be talking to?

I should think so.

My method for debugging these problems involved hex dumps of the compiler 
generated code (objdump -D is good) and a hex calculator to link everything 
together.


The "library is younger" message comes from a date check between the flat 
headers of the executable and libc.  Try flthdr -p to see what values are 
really present in the two executables.  This check doesn't have anything to do 
with relocations so if something is going awry mid way through, I'd be 
suspecting memory corruption.

[uClinux-dev] Info on processor

[Ganesh Kumar]

  Hi,
   
  Need some guidance in choosing a low cost microcontroller (under 5 USD) with 
support for the following peripherals and can run uclinux
  1) Ethernet Interface
  2) USB Host
  3) I2C
  4) SPI
  5) External Flash & SDRAM interface
   
  I have a couple of MCF52x processor, but the price seem to be a bit high.
  How about the LPC2468..Have any one run uclinux on this processor 
before..Also i'm looking at the Atmel AT91SAM9260..I'm not sure about the 
uclinux support on this.
  Appreciate your inputs
   
  Thanks
  Ganesh
