I want to dd the boot to eMMC ,how can I do?

[tinysun]

the img can not suport the emmc dev.

[chenxudong2020]

Synology support emmc?

[tinysun]

Synology support emmc?

i am not sure,but linux can be.

[fbelavenuto]

I believe the DSM kernel will not work with MMC type disks, but I can test.

[crazyshitass]

Need this function, hope the driver issue can be fixed.

[tinysun]

I am not sure，if the boot fews can be use，it is a good news。
samewhere I saw the emmc boot can be suport with 6.0.2,and a part of 6.1.7,and the 7.0.1beta.
the idea is rewrite the "PID、VID".? the same way can be using for usb disk to system disk.

支持 我也需要这功能

[tinysun]

咱们用英文支持一下，楼主本来就是巴西人，英语就不好，你这发中文。。。

[tinysun]

any idea？

[fbelavenuto]

Please wait, I'm solving others issues.

[fbelavenuto]

I've added the modules, please test. I do not have a machine with MMC/eMMC, then I not know if it works!

[tinysun]

thanks very much,I am testing it.And feedback as soon.

[tinysun]

the /dev is not find the mmc dev.

I tested on a laptop that has eMMC (MYRIA MY8311B) and it gives me the error in the picture.

it looks like not drive the emmc driver.can you show the /dev ? or tell us the fdisk -l ?

the mmc is not working.

[adixus]

[tinysun]

the mmc dev may be not drived. I am the same.

[fanmain]

Recently, I have compiled the startup on my J3455+32G EMMC and successful. My steps are

1. Use the U disk to guide configuration to compile DSM to ensure that the module contains MMC
2. Select ‘Start DSM directly’ to ensure that the U disk can start DSM
3. Use the DiskGenius disk to copy the U disk to EMMC
   Key point:
   *The compilation module contains MMC (ARPL default)
   *Starting from EMMC, you must choose to start DSM directly
