I have an imx53 QSB with a marvell 88w8787 ( Linux developer community calls it sd8787) inserted in the SD-slot. I am trying to write a WEC7 sdio client / ndis driver for self-learning purposes. Nowhere in the web I could find a relevant datasheet or some kind of programmer's reference guide for this SOC -- essentially the register set/bits and host<->card protocol. Can someone please provide me a link where this is available or email me ( firstname.lastname@example.org). I would be grateful.
I tried to reverse engineer the Linux mwifiex driver source code with limited success. This card/driver after integration with the yocto community BSP works perfectly well and I could get dynamic, live debug logs
BTW, I don't understand, why some companies don't publish such essential things publicly, as if they are great national secrets, hiding under some NDA-required crap ? Here I could understand that some kind of crypto involved like WEP WPA...but still, they could be kept as black box stuff and other details divulged.
