I dont get it, RTEMs has a port of sdmmc stack https://git.rtems.org/rtems-l ibbsd but not all the drivers are using it. For example I saw, stmf32 implement its own command sending mechanism. Shouldnt that be generic, the sending of commands. Only the lower controller level detail should change.
Also I don't get the connection with freebsd code, do we use that code directly in RTEMs, is all of that ported??? Just want to understand the structure of RTEMs... cheers, Faizan On Mon, Apr 3, 2017 at 10:43 AM, Sebastian Huber < sebastian.hu...@embedded-brains.de> wrote: > On 03/04/17 02:06, faizan khan wrote: > >> Is there an sdio stack in RTEM because I could not find out.
