What are correct values for machdep.pccard.mem_{start,end} ?
I have a similar problem for the same pccard (MA401) but under
FreeBSD-CURRENT (OLDCARD) and a Compaq Evo N160 laptop with
128MB RAM.
> : pccardd[49]: No card in database for "(null)"("(null)")
after I had done 'pccardc power 0 1'
I had an FreeBSD-4.6 installation that did work fine with the card.
What have changed from 4.6-RELEASE to CURRENT?
In CURRENT the file
FreeBSD/src/sys/pccard/pcic_pci.c included:
#define CARDBUS_SYS_RES_MEMORY_START 0x88000000
sysctl:
machdep.pccard.mem_start: 655360 (0xA0000)
machdep.pccard.mem_end: 1048576 (0x100000)
In 4.6 the file FreeBSD/src/sys/pccard/pcic_pci.c included:
#define CARDBUS_SYS_RES_MEMORY_START 0x44000000
But in CURRENT it does not seems to be used (0xd0200000 instead), and it to
me also look as 0xd0200000 is allocated twice for pcic0 and fxp0!.
Extract of dmesg:
