Rock5b plus Can't see onboard EMMC device(s)

[pascal71]

What happened?

Installed Riek's Ubuntu 24.04 (server edition) on NVME (could'nt get installed using rkdeveloptool). It starts up. But when I try to find the EMMC devices, there are none with lsblk.

Only:

pascal@rock5bp-n01:~$ lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS loop0 7:0 0 94M 1 loop /snap/lxd/29579 loop1 7:1 0 69.2M 1 loop /snap/core22/1383 loop2 7:2 0 33.7M 1 loop /snap/snapd/21761 loop3 7:3 0 69.2M 1 loop /snap/core22/1438 loop4 7:4 0 94.5M 1 loop /snap/lxd/29733 mtdblock0 31:0 0 16M 0 disk nvme1n1 259:0 0 3.7T 0 disk ├─nvme1n1p1 259:1 0 4M 0 part └─nvme1n1p2 259:2 0 3.7T 0 part / nvme0n1 259:3 0 1.9T 0 disk

I'd expected to see the EMMC device.

Strange. I have a Radxa ROCK 5B Plus 24GiB as well. But the model with internal (onboard) eMMC is not yet for sale, afaik. They will be later this year on the market. The ones for sale at AliExpress do not have the internal eMMC as yet. May I ask where you obtained your one?

[pascal71]

@hanvinke

You are right. The EMMC component is unsoldered on the board; which is probably the hardware equivalent of 'vapourware'. I actually bought 3 of these for the onboard EMMC but alas.. :)

No worries; this issue can be closed. What is not there, can not be found.

I will open another issue for the POE hat that doesn't want it's fan to spin, even when I instruct it do so manually.

[pascal71]

Issue can be closed as there's no EMMC soldered on the current Rock5b-plus boards.

I have the similar problem. My board is Orange Pi5 Plus 16GB + 256Gb eMMC module installed. Normally the eMMC module is visible under /dev/mmcblk1 name but I see the SD card under this name only. eMMC is not visible at all so dd on it is not possible.

@pascal71 No worries too - it is still a wonderfull board. Flawless 4K mpp youtube and 10 bit HDR X265 video play, it all works perfectly! So no regrets buying it.

[pascal71]

No worries. Now onto getting POE 25W 's fan running Next issue :)
