New owner of 4 SE, read what I can on booting from NVME, but all I can find doesn’t seem to apply to the 4 SE.
Anyone know if you can boot from NVME, and, if so, how?
Rock 4 SE -- NVME boot?
But did you try anything?
ROCK 4 SE doesn’t have on board SPI flash
https://wiki.radxa.com/Rockpi4/hardware/models
so you need SD card or eMMC for NVMe booting.
More info can be found here:
Thank you for response. I’ve read all that and I’m still confused on whether or not the 4 SE can boot from NVME (without SD card). Is it possible?
No, its not possible. You need SPI flash - i think you can solder it if you are skilled for this kind of operation.
Yep, spent days trying the various methods. I’ve installed/mounted NVME disk, 4 SE recognizes it. Installed images (a few times), but 4 SE doesn’t boot from NVME. Get a green light, but never a blue.
If I boot from SD card with NVME installed, I can see the NVME with system files and all partitions.
Instructions on Rockpi4/install/NVME - Radxa Wiki show methods that require SPI which is not present on the 4SE.
So, that’s why I’m stuck.
This method / OS (almost) always works - SD boot, NVME root. But haven’t tried it with SE since don’t have this variant …
Thank you! Had not tried armbian distro, the missing piece was the armbian-config that let me point to the nvme.
Still need the SD card for some reason, but I’m running system from nvme.
Thanks for your help!
kool. I am a clueless ms windows numpty for many decades, yet I still have hope. kudos.
I purchased WINDBOND 25Q64FVSIG and I’m going to solder it on Rock 4 SE. I will let you know what will happen
