I started uC5282 80 MHz testing from today.
So, i am just testing RAM based and Flash based  booting.
After that i will try to bus interface with external chipset (e.g CPLD).

Changed flag options from your comment;
ARCH_DEP_LDFLAGS += -Wl,'--defsym' -Wl,'_FlashSize=16M'

Compiles were OK,
But, flash booting was fault with below error messages;

RAM booting is worked.

Do you have a any ideas for solve flash booting?

Subject: 80 MHz version of uCDIMM ColdFire 5282

I have a question to those using the 80 MHz version of the ColdFire uCDIMM
5282.  How do you connect this to external logic such as an FPGA?  Here's
the bus timing section of the data sheet:
