Subject: sd8787 (mwifiex) on big endian system
Date: Mon, 26 Aug 2013 12:27:59 +0200 [thread overview]
Message-ID: <20130826102759.GA14350@gmail.com> (raw)
As the subject suggests, I am trying to use the SD8787 on a PPC
system. I have found a few endian related issues (submitted a few
hours ago), but it is still not working.
So my first question, has anyone successfully used an mwifiex device
on a big endian system?
Also, I have found that the chip seems to signal interrupts before its
internal registers are in a consistent state. Specifically, the
sdio_ireg and wr_bitmask seems to be out of sync. Inserting a small
delay in mwifiex_interrupt_status (sdio.c), currently 50 us solves the
problem. Is there some bit that should be polled here to make sure that
the registers are in a consistent state?
