MMC: no card present custom IMX6 UL Board

[nachodiz]

Dear all

Our board is succesfully booting from SD1

But UBOOT says MMC: no card present

Sometimes it detects the card  mmc0 is current device

But the major of the times its not being detected

We have no physical (mechanical card detect)

How can we fix the issue ?

King Regards

Hello,

  First, as I see from boot log, PMIC is not defined in U-boot.

It should be defined in U-boot with following rebuild.

You may look at “[PATCH] u-boot: add pf3000 support on imx6ul-14x14-evk board”

 To support eMMC it is needed to rebuild U-boot ; please refer to

section 5.5 (U-Boot configuration) of “i.MX_Yocto_Project_User's_Guide.pdf”.

Have a great day,

Yuri

We are workind from sd card (sd1)
boards are fused to boot from sd card sd1 bus
emmc is at sd2

the evk has card detect on sd1
mechanical
i think this is our problem
we have no mechanical card detect

it boots from sd1
but uboot is not seeing sd1

Some times it boots!

Hello,

  is Your memory settings in U-boot just the same as for DDR stress test

(with taking into account results of calibration) ?

You may try to set SD1_CD active for testing.

Regards,

Yuri.

[nachodiz]

No its not ...

1.

   You may try to set SD1_CD active for testing.

2.

  To avoid memory issues - please provide correct initialization in U-boot 

(Please refer to U-boot chapter in "i.MX_BSP_Porting_Guide.pdf").
