Hi Biser,

Thanks for the reply.

Yes this is the custom board. Micron Chip MTFC4GACAJCN-1M WT-TR with size of 4 GB.

Hello Karthikeyan,

There was some issues on partition switching with U-Boot 2017.01. Please, update your U-Boot to the current latest 2018.01 version.

Best regards,
Kemal

I can able to get the clk in MMC2_CLK , What should be the frequency of this pin ?

Data pins from 0 to 7 is in high (pulled up).

Please provide me the guidance.

Are the PinMux and IODelay settings in <Processor SDK>/board-support/u-boot-<version>/arch/arm/dts/am57xx-idk-common.dtsi, <Processor SDK>/board-support/u-boot-<version>/arch/arm/dts/am57xx-beagle-x15-common.dtsi, <Processor SDK>/board-support/u-boot-<version>/arch/arm/dts/dra74x-mmc-iodelay.dtsi and <Processor SDK>/board-support/u-boot-<version>/board/ti/am57xx/mux_data.h matches your schematic?

Attached the Schematic of MMC . Its same as am57xx-evm Design.

Do I need to change anything on the pin configuration ? Because the MMC2 pins are dedicated from processor.

Your board doesn't have an EEPROM right? On which design, TI AM5728 IDK or AM572x GP EVM, is your board based?

Hi Kemal,

Thanks for the reply. Yes I dont have eeprom.

As I mentioned above , the model is TI AM5728 IDK.

U-boot log :

******************************************************************************

U-Boot 2017.01-00443-g340fb36-dirty (Jan 16 2019 - 17:01:23 +0530)

CPU : DRA752-GP ES2.0

Model: TI AM5728 IDK

Board: UNKNOWN(BeagleBoard X15?) REV UNKNOWN

*******************************************************************************

The board name by default its taking beagle-x15. I m compiling the am57xx-evm.dts file which includes am57xx-beagle-x15.dts.

Renaming am57xx-evm.dtb to am57xx-beagle-x15.dtb, since my board name is beagle-x15 in u-boot arguments.

So you are messing up the things here. Can you apply this patch and check whether the eMMC is detected?

cd <Processor SDK>/board-support/u-boot-<version>/
git apply 0001-AM57xx-Hardcode-EEPROM-board-name-to-AM572IDK.patch

Hi Kemal,

Thanks for the reply.
PMIC has got damaged. I will update the status once its get done.

Hi Kemal,

I have done some fix related to PMIC and Regulators based on our custom board.

Now EMMC is detected and Working.

Thank you soo much for the support.

Can you please share the procedure to partition the EMMC , flash & Booting procedures.

0 Kemal R. Shakir over 6 years ago in reply to Karthikeyan R

TI__Guru 55345 points

Sure. You can use the fist method shown in this post or the second method shown in this post.

Hi Kemal,

Device is booting from EMMC. Thanks for the input.
