Hi everyone.

 

We can't boot with emmc 4.5 on my custom board.

before our Micron emmc(4G) was no problem and worked perfectly.

 

Since after old one has been discontinued. we need to change emmc to hynix

I have been digging about this for 1 month...  however I'v been still stuck this.

 

we use i.mx6ull and hynix emmc 4g (H26M31001HPR) 

 

 

EMMC 5.0 and EMMC 5.1 work on i.MX6 

i'v read already this.

but our kernel is 4.1.15_2.0.0 version. so the source code is quite different between here.

 

and we changed boot_cfg thousand of times. :-(

here is our boot log when i tried burn with MFGTOOL
