Since posting this email, I had found BCSR definition in the manual.
It appear that this address is not correct. (I have 852T Fads board).
Original fads.h file had
#define BCSR_ADDR ((uint) 0xFF080000)
and I was getting sigabrt in serial.c (serial_init() call). Looking around I found another definition,
#define BCSR_ADDR ((uint) 0x02100000)
This seems to work for serial ports, but had no effect in fec.c file (fec_init() function call) and I thing this is the cause of my fec / LXT972 (which I have sent in different emails before).
Uptill this point,
IMMR 0xff000000 SDRAM from 0x00000000 for 32 mb Flash from 0x02000000 for 16 mb
Yesterday I change Flash to start from 0x40000000 and again I am getting sigabrt serial.c:serial_init() function. This time none of definitions are working (all get sigabrt)
#define BCSR_ADDR ((uint) 0x02100000) #define BCSR_ADDR ((uint) 0xff010000) #define BCSR_ADDR ((uint) 0xff080000)
Well, how can I correctly calculate BCSR_ADDR for my environment.
Thanks

Can anybody tell me where this definition comes from. Cannot find any reference.
For a desription of the register see the FADS User's manual; the address was chosen when setting up the memory map for the
system.
