SD-MMC over SPI on PSC6

SD-MMC over SPI on PSC6

[Fabio Tosetto]

Hello, I have an embedded system with an on-board processor powerpc 
MPC5200B
and Linux kernel 2.6.22,
I must turn over to MMC SPI on the PSC6.

The MMC over SPI is connected to MPC5200b, here's how:

  MPC5200B

|

                       |                        
                                         |     SD CARD
         ETH_17 |---<------------IRQ (in)------------------|   MMC over SPI
                       |                                                
                 |
                       
|                                                                 |
         PSC6_0 |---<------------SPI_RXD (in)------------|
                       
|                                                                 |
                       
|                                                                 |
         PSC6_2 |--->------------SPI_TXD (out)-----------|
                       |                                                 
                |
                       |                                                 
                |
         PSC6_3 |--->------------SPI_CLK (out)-----------|
                       
|

Now on the menuconfig enabling these options:

$ make ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnu- menuconfig

Platform support  --->
   [*] MPC5200 (L25R) bugfix support
   [*] Freescale Lite5200 Eval Board

Device Drivers  ---> SPI Support --->
   [*] SPI support
  <*> Freescale MPC52xx PSC SPI controller

Now I have applied those patch:
http://www.mail-archive.com/spi-devel-general@lists.sourceforge.net/msg00150.html

Now on the menuconfig enabling these options:

$ make ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnu- menuconfig

Device Drivers  --->  MMC/SD card support --->
 [*] MMC debugging
<*> MMC block device driver
<*> MMC host test driver
<*> MMC/SD over SPI

Is correct applied those patch and enable those options into menuconfig?

thanks Fabio

Unwise unless you really want to trash every MMC or SD card
you insert ...


You might consider not crossposting to such a large proportion
of the free world, by the way.
