anyone with ColdFire® M5282EVB? (support for Student Learning Kit)

[legacy]

let me know 

[legacy]

just a note

Code: [Select]

m68k-unknown-linux-gnu-gcc -mcpu=5282 -c hAllo.c -o hAllo.o
cc1: error: unrecognized command line option "-mcpu=5282"

mmm, is there a difference between

Code: [Select]

target=m68k-unknown-linux-gnu

and

Code: [Select]

target=m68k-elf

?!?

because, if so, I have to modify the crossdev script 

Code: [Select]

m68k-unknown-linux-gnu-gcc -v

gcc version 4.1.2 (Gentoo 4.1.2 p1.6)

or, is v4.1.2 just too old for that ?




edit:

Code: [Select]

m68k-unknown-linux-gnu-gcc -m528x -c hAllo.c -o hAllo.o

this works

[ale500]

What does the target dump/help looks like ?

[Kalvin]

You using GCC anyway? 

[legacy]

You using GCC anyway? 

yup, until I will receive my personal license for CodeWarrior/Coldfire

currently I own a license for EZ328, which doesn't include Coldfire and
any BDM cable support. It will take a couple a weeks through a reseller
because I have also ordered a couple of cables

and, as usual, gcc has failed on its first try
but don't worry, my bad attitude against Gcc
is still far from being changed

it's a purpose that drives me: I'd like to finalize a virtual machine for this board
in order to provide some good gear to a local college's lab

the external flash contains "dbug"
sw.all on, except sw8=off, boots it

anyhow, the problem was gcc

good, the above is interesting, gcc v4.1.2 was built by crossdev with the following set

Code: [Select]

crossdev --b 2.25.1-r1 --g 4.1.2 --l 2.22-r1 --k 4.3 -s2 -t m68k-unknown-linux-gnu --without-headers -v

I am going to give a try to a new profile, v4.3.1

Code: [Select]

crossdev --b 2.25.1-r1 --g 4.3.1 --l 2.22-r1 --k 4.3 -s2 -t m68k-elf --without-headers -v

and don't look at my env

M5282 belongs to core-v2 class

bought two USBMLCF for a discount
because discontinued and replaced
by the U-MULTILINK-FX 

I don't know about "clones"

gcc v4.2.4 --target=m68k-elf:  it works

so, no one on ColdFire® M5282EVB or similar boards.

[nctnico]

so, no one on ColdFire® M5282EVB or similar boards.

No. I think I had one or a similar board a decade ago but I send it back due to lack of programming tools.

[legacy]

it means no examples and no people around
damnit damnit

I wonder why they have chosen ColdFire® for the laboratory
it doesn't seem the best choice, any how I was asked to
provide equipment, get started, a few examples, and boards

and I am doing my best with gcc because they haven't
approved the budget requested for CodeWarrior 

also, they haven't approved the purchase of the usbdm
therefore I am obliged to use gdb over the serial line

the M5282EVB board comes with two serial ports
console, and auxiliary, while the Student Learning Kit
comes with one serial port 



the only good part of this sad story: the laboratory assistant
is a she, a very pretty girl, let's' add a bottle of good wine
(might be a date for dinner?) to the purpose 

[nctnico]

And get some ARM development boards while you are at it. There is a seller on Ebay which has very nice LPC1768 boards (USB host, ethernet, CAN, color TFT display) for around $70.
Just forget about the Coldfire. Some distributors try to push it hard but there just isn't any support behind it unless you are going into very high volumes where spending several $k on the tooling isn't an issue.

[legacy]

And get some ARM development boards while you are at it

well it's not my choice, they decide what they want in their lab
for my personal use I have no problem with arm boards by Olimex

mmm, it seems they have chosen ColdFire® because they have
a course where they study assembly 68k, therefore the laboratory
needs to have some 68k gear, and ColdFire® is close to it

[nctnico]

Why do they even bother with the 68k? It is obsolete and the lab seems to be a lost cause. Just take the woman out to dinner and don't get involved with the lab (don't mix personal life and work  ).
