TDA4VH-Q1: One of my Customer boards stuck with trying to boot from MMC2

Hi Sai,

(1)  I try this SD card on my other same board , it works fine.  ==》 SD Card is OK

Are you booting from MMC2 on both boards with the same process?

On my TDA4VH board:  MMC1: eMMC; MMC2: SD card.

On good board, can boot from SD card on MMC2 port. 

What is cause of the errors?

(1) SD card？

(2) DDR ?

or something else?

Hi Sai,

For the bug board, what eMMC chip are you using? Is it eMMC 5.1 JEDEC compliant?

Matt

Hi Matt:

 all my board use MTFC32GSSAQHD-IT , which is  5.1 JEDEC compliant.

Hello  Matt, do u have further comment on this question?

Hi Sai,

Typically on our TDA4VH boards, MMC0 is used for eMMC and MMC1 is used for SD. MMC2 is usually used for SDIO purposes and not boot supported.

• Is part of the custom configuration on your board changing this to be MMC1 for eMMC and MMC2 for SD?
• Can you also share you're software setup and SDK version?

Best Regards,

Matt

Hi Matt:

 we seems have some misunderstanding.

   Base on my uderstanding the datasheet, on TDA4VH's main domain , It only has MMC0 for emmc and MMC1  for SD.  There is no MMC2???

   My sdk version is 9.1.

---- My opinion:

 my 16 pcs customer board work fine . but only this board report this error.  I donn't think it is a  software problem.  But I need to minimize which part of the hardware is wrong.
