Hey Greg, That looks like a cool module. The issue for me is that I need high speed Wifi connectivity (20 Mbps+, ideally 50Mbps+) for my upcoming projects. SPI/UART modules like this one usually have much lower throughput.
This module does have a 50Mhz SDIO interface, so if it can use 4 bit mode, it could work. However, the ATWIL3000 Linux driver on Github <https://github.com/linux4wilc/driver> does not appear to have an open license– all the code is marked "All rights reserved". Is this the driver you were referring to? I am looking at porting a USB Wifi driver from FreeBSD... The thing about porting a USB driver from FreeBSD that attracts me is that I could at least have access to a whole family of fast Wifi hardware that way. And in the best case scenario, if I can create a compatibility layer, then we could use a variety of FreeBSD wifi drivers. cheers adam On Thu, Jun 11, 2020 at 1:43 PM Gregory Nutt <spudan...@gmail.com> wrote: > Hey, SAMA5D2 guys, > > I have been looking at the ATSAMA5D27-WLSOM1 Evaluation Kit.
