How to recover from a failed emmc boot?



Recommended Posts



I have bricked my system by installing the  rk3399 legacy multmedia framework. It was installed on emmc.

I was able to recover my system by using the P11 jumper to skip the boot on emmc, as explained in the doc, and now my system runs on a SDCard.

The problem is, it seems that I cannot access the EMMC anymore -- it does not show up /dev. My intuition is that the P11 jumper disables the EMMC altogether.

Am I write and if so, how can I access the EMMC again? I would like to be able to read it again (I had important data, notably unison synchronization files) and reinstall a fresh OS on it.


Any help would be welcome!
