Dear;

       Currently NXP IMX93, model is PIMX9352CVUXMAA, software BSP version is Linux 6.1.22_2.0.0, storage uses LPDDR4+EMMC configuration, EMMC model is SDINBDG4-16G-XI1; When UUU is used to write uboot, run the uuu -V -b emmc flash.bin command. If the MMC cannot be identified, the following information is displayed:

Detect USB boot. Will enter fastboot mode!

         Is LPDDR4 not configured at present the cause of the problem? Excuse me: Is there any IMX93 debugging guide documentation?

         Thanks!

         Best Regards!

If the board can't detect the MMC, it  can't flash the firmware.

 

MMC: no card present

-->Does this problem occur all the time or occasionally? This is a very critical issue.

Dears;

           At present, it has been verified on the development board of Feiling that all are normal, and my own board has just been welded and debutted, and it is found that EMMC cannot be recognized, resulting in no burning,  which is being excluded.

 

         Best Regards!

Dear,

        The problem has been eliminated, the hardware design in the EMMC line CLK reserved capacitance to the ground, after removing it.

        Best Regards!
