Another question. Last time you told us to replace four driver files on the nodes:

Are they obsolete now, so that I’ve gotta flash the nodes with a completely new O/S image anyway? And: If yes, will the reflashing overwrite all files on the eMMC storage of the node? I’ve installed quite a bunch of software in the last weeks (including a complete Ceph cluster) and really can’t perform this work for a second time.

In the installation instructions, you link to a different image BTW: image-release-rockchip-format-blade3-ubuntu-desktop-240327.img.xz

This command works. Thank you.

If you’re using the previous ko file, now you just need to replace miop.ko in your cluster. The previous driver performance was not as good as it is now.

#4

…but not the file, which came with your last package, as this was for the control board, right?! Where can I then get the miop.ko I’ll have to install on the nodes?

If you don’t want to flash a new Blade3 image, then use the drivers provided here.

#6

This is what I’ve got now:

mixtile@blade3n1:/lib/miop$ ls -al *.ko
-rw-r--r-- 1 1289 1001 466520 May 17 16:14 miop-ep.ko
-rw-r--r-- 1 1289 1001 817104 May 17 16:15 miop-ep-net.ko
-rw-r--r-- 1 1289 1001 680336 Apr 25  2025 miop.ko
-rw-r--r-- 1 1289 1001 430936 May 17 16:15 miop-reg.ko
-rw-r--r-- 1 1289 1001 730112 May 17 16:15 pcie-ep-rk35.ko

So I’ll just have to upgrade miop.ko with the version from the file you’ve just published and then reboot the whole cluster, right?

#7

“miop.ko” is a file of OpenWrt.
/lib/modules/5.15.150/miop.ko

#8

I meant the miop.ko, which comes with mod.tar.
