Hey, SAMA5D2 guys,
I have been looking at the ATSAMA5D27-WLSOM1 Evaluation Kit. I am
impressed. It is based on the SAMAD27C and the ATWIL3000 wireless
module. I am tempted to buy one.
The ATWIL3000 has an SDIO interface to the Wifi (like the Broadcom
chips) and UART interface to the Bluetooth. It runs $150 USD at
Mouser. An open Microchip driver is for the ATWIL3000 is available in
github. Anyone interesting in a fun Wifi project?
Greg

Takeyoshi,
Hey, in case you are interested, I got the SDMMC driver port working for
reading data today. It's quite a mess, and on a private branch. I will try
to get it working for writing, clean it up, and push it to this branch in a
few days.
Thanks so much for your help!!
cheers

Hi, I've been working on the SDMMC driver off and on. I still haven't got
it working, but I am making some progress. Here's a log of register reads

I have a MMC sniffer and logic analyzer hooked up and can see traffic on
the SD Card bus under U-Boot. Under NuttX, nothing. I am going to try to
capture a register log like this one under NuttX, and compare; and maybe
try to replay the U-Boot sequence under NuttX to see if I can get signals
on the SDMMC bus. If you have more ideas, I would love to hear them.
cheers

Takeyoshi,
I finally got the new sama5 sam_sdmmc.c driver to compile. I haven't
tested it yet, so I don't know if it actually works... I pushed the code to
the branch, I am attaching the config I used.

I did some work on the SDMCC driver today, it compiles now and I

still
not sure everything is right, for instance why do I have to specify
SDMMC0_SIZE? The sama5d2x_memorymap.c file seems to need it. But it
should
not be operating in memory-mapped mode, so I'm confused.
Here are the config settings I used:
