That information is currently not public.
Please Contact your Nearest TI representative in order to receive schematic information.

hi Boyko,
if i want to shutdown the power which is supply to eMMC card, and which register i need to configure?
thanks!
Hi,
The power is enabled by the PMIC which is information i cannot provide you either.
You can examine the board file of the baord kernel/android-3.4/arch/arm/mach-omap2/board-XXXX.c
and you will find the construct for the mmc card, it must contain power child element that will allow you to power it down,
You can find more information that can help you better build your mmc driver at:

hi Boyko,
thanks for your information. and i have another question on HS200 tuning.
1. is it correct that Figure 24-54. SDR104/HS200 DLL Tuning Procedure in TRM?
2.when i check DLL[0] is always 0 ,unlocked; and i set AC12[22]=1, but the DLL[0] is still 0 ,unlocked .why?
thanks!
Hi,
The procedure is correct,
Did you confirm you booted and identified your MMC card (there is a guide in the same section how to do so)

Boyko
hi boyko,
i have download the bin file ti-glsdk_omap5-uevm_6_02_01_02_linux-installer.bin
from http://downloads.ti.com/dsps/dsps_public_sw/glsdk/6_02_01_02/index_FDS.html
and how can i get the linux kernel source code about this version?
and i use the command git clone
Linux Kernel | git://git.omapzoom.org/kernel/omap.git |
is empty!
thanks!
hi boyko,
"Did you confirm you booted and identified your MMC card (there is a guide in the same section how to do so)"
your mean?
I use uSD card to boot kernel, and eMMC do tuning test(4.51 support HS200), when do tuning find the MMCHS_DLL[0] DLL_LOCK = 0x0, always unlocked.
why alway unlocked?
thanks!
hi Boyko,
i have a question about MMC ,I use CMD18 to read data and find between every data block the mmc clock will stop and set to low for a moment by the host, but I can not find where to set the register to modify that, I want to the mmc clock is alway on at whole read operation.
thanks!
