Hello Gery,
we plan to solder up to 4 WL1271 chips on our board (It will be the
ready-to-use chip from LSR).
After a short look into the driver source code from the vanilla Linux
kernel, we saw that the driver is not fully capable to handle multiple
instances.
One critical issue we found are the wl12xx_set_platform_data and
wl12xx_get_platform_data function calls. They configure the IRQ for the
WLAN chip.
I think every WL1271 should get a separate IRQ (i.e. interrupt capable
GPIO line). Does anyone has an idea how to configure the IRQ
independently for each WL1271 chip? Especially on a X86 platform where
there is no board specific configuration like on an embedded ARM target.
Another issue: every chip needs a specific NVS file (which holds the MAC
address plus some other chip-specific settings). Currently, there is
only one NVS file in the whole system. But it should be very easy to add
some kind of instance number to the NVS file name to have a separate
file for each chip.
Are there any other known issues when there are multiple WL1271 chips in
one system?
Any help is appreciated.
cu,
Daniel
