I think I might have just destroyed my Rock Pi 4B+ v1.6.
I have the M.2 extender, the heat sink, and a uSD to eMMC adapter.
This v1.6 Rock Pi 4B+ has a small eMMC module already bundled on it, with Twister OS installed there. It was booting just fine (off the eMMC). On a separate PC, I wrote the
image to an NVME SSD and confirmed that a lsblk command on the RockPI showed the NVME. All was good.
The instructions at Rockpi4/install/NVME - Radxa Wiki clearly state that I need to remove the eMMC module to boot off the NVME. I popped the eMMC module off the board, and where I was expecting to see 2 eMMC connectors/socket/rails (like on the v 1.4 board), I instead see some glue and a scattering of little round contacts/solder balls. Where are the eMMC connectors/rails?
Now, even with the NVME in place, it won’t boot – and I can’t get the eMMC module back on tightly. It seems like that included eMMC module was really not meant to come off the board? Power gets to the board - the green light comes on - but then nothing. No blinking blue light. Nothing. Can I recover this? I have no issue with not using an eMMC.
- Can I boot the 1.6 board without the eMMC module? I think I have lost the eMMC first stage loader, right?
- What are the exact differences between the v1.4 and v1.6 board?
- What is the difference between a B and a B+ board?
thanks in advance for any help
