[uClinux-dev] coldfire M5272, linux-2.6.x

[Daniele Ziglioli]

Hy,
I've tried to compile, without success, the last kernel linux-3.x for the
EVM5272 freescale board.

My environment:
Ubuntu 10.04
m68k-uclinux-tools-20101118.sh or
freescale-coldfire-2011.09-23-m68k-uclinux.bin
uClinux-dist-20131024.tar.bz2
I've tried various dist and compiler (codesourcery and uclinux) ... without
success.

Could you suggest me a working tested environment to get compiled a recent (>
linux-2.6.x ) kernel,
for that board (or a different similar one) ?


thanks in advance ,
Daniele

Hi Daniele,

Ubuntu 10.04
m68k-uclinux-tools-20101118.sh or freescale-coldfire-2011.09-23-m68k-uclinux.bin
uClinux-dist-20131024.tar.bz2

Could you suggest me a working tested environment to get compiled a recent (> linux-2.6.x ) kernel,
for that board (or a different similar one) ?

What failed exactly?
Can you show the compile logs?

well, finally I've compiled the last 20131024 with codesourcery toolchain, but ...

I've then started from the config of the M5272C3 EVB (that is is the more
similar to mine),
and changed kernel execution form add 0x400.
The same I've done before with a linux-2.4 kernel, and that work.
But when i do go 0x400 nothing happen on the console.
I've an ICDFZ 64K (P&E) and the only thing that I could see , looking the
address of the assembler line
where the cpu is looped in the "calibrate_delay" function.

attached the config used.

did you know if the last uclinux (linux-3) version run on the M5272C3 EVB ?

thanks, for any information.

If it's looping while calibrating the delay loop, the timer interrupt
is probably
not working.

You probably want CONFIG_RAMSIZE to be set to 0x1000000. It should be all
of RAM, not with the vector region size taken of. Otherwise it looks
pretty normal.

I don't think I have run it on that board. I have run it on a few other
ColdFire boards (like the 5208 for example).
