[En-Nut-Discussion] xmem testing - problem

[Tomek]

Hi

I'm new, and i've made my own ethernut board (with ISA card), but even with
no card I have problems with testing XRAM (using 'basemon').
As a result of testing I get:

BaseMon 4.0.2
Nut/OS 3.3.2.1
Compiled by AVRGCC for ATmega128
External RAM Test... 0 bytes
Banked RAM Test...   none
Detecting NIC...     none
I/O Port Test...     OK

...and that's all, but when I use this way of accessing xram:

write:
    *adr=data;    where adr - pointer, data - test data
read:
    data=*adr;
or even
write:
    memset((uint8_t *)adr,data,length);

everything seems to be OK !! The whole ram area is written and read
properly.
What may be wrong ??
Sorry for (maybe) silly question :)
Any ideas?

regards
Tomek
