Error while flashing custom linux image on emmc

purvi_billore1 — Fri, 04 Oct 2019 10:39:02 GMT

Hello,

I have made custom linux image for custom board with iMX-6 processor through yocto for sd-card and for emmc; when I flashed image on sd-card through dd-command it is properly flashed and running.

Now, when I tried to flash the image on emmc through dd-command it is throwing the below error:

Hello Purvi,

Apparently your eMMC is damage or Please try the DDR Stress Test : perhaps memory re-calibration is needed.
