I think I've found it, around
pccard/pccardd/cardd.c:585
we still totally ignore the card offset and force it to 0x4000. My earlier
tests were working as I am using a current that doesn't set the MDF_ASSSIGNED
flag. This is obviously wrong in general and breaks the raylink driver.
It appears that some of the logic that tests whether we have an ed card is
broken and that the memory settings are adjusted whatever card is used.
Is my reading of the code right?
pccard/pccardd/cardd.c:562
if (!(strncmp(sp->config->driver->name, "ed", 2) == 0
&& (sp->config->flags & 0x10))
&& (cisconf->memspace || (defconf && defconf->memspace))) {
As I'm not really familiar with this code, could someone fix this.
Many thanks,
Duncan
