Boot nanopim4 from nvme

[pkfox]

Hi all, I would like to boot my nanopim4 v2 from a nvme ssd disk if possible - I tried using armbian-install as mentioned on a thread on here and received the error "partition too small" the disk is a 1Tb and has one partition - any ideas ?

Here is the output from fdisk

and from cat /etc/os-release

Try this: delete partition on NVBME and leave the installer to make it for you.

[pkfox]

Thanks @Igor I'll try that, sorry for the late response

Hi @Igor I deleted the partition as you suggested and ran armbian-install, it looked promising to start with - I saw a message that said copying files please wait... - then I was prompted to press a button to reboot. The device starts flashing a red LED as is normal  but that's as far as it gets, it wont boot - any ideas as to what I need to do ?

@Werner the problem I have, is, the nvme adapter which houses the ssd drive https://www.friendlyelec.com/index.php?route=product/product&product_id=262 covers the uart connection - is is possible to do uart via the gpio ?

Hi @Werner I found a way to connect my USBTTL to my board with the USB end plugged into my Linux Intel NUC

From a terminal on my NUC I entered

picocom -b 1500000 -r -l /dev/ttyUSB0

and received this

But I can't enter text , it just sits there - what am I doing wrong ? It's been years since I did this sort of stuff

[Werner]

This output isn't related to uboot. So I assume you don't get any output whatsoever which means broken/missing boot loader.

I'd try to boot from fresh sdcard and then start investigating.

[pkfox]

Thanks @Werner I am booting from a fresh sdcard and it boots perfectly I just dont get anything back using picocom - should I connect the uart stuff before I power on the board ?

[Werner]

Well the other variant of course is that it might be connected wrongly . Tried to flip RX and TX lines? common mistake having these mixed up.

If it boots from sdcard there MUST be ouput to the debug serial.

[pkfox]

I have one of these which has a moulded connector onto the pins

[Werner]

Hm as for me I only have standard jumper wires for debugging my stuff. last but not least because it does not connect 5 volts which isn't necessary anyways for serial interaction and reduces the risk of frying a board by connecting this wrongly.

[pkfox]

So I appear to have run out of ideas 😞 thanks for trying to help me

@NicoD do you still have your m4v2 and may verify uart connection and working debug console? thx in advance

[pkfox]

@Werner I have uart working now - on my uart adapter there's a switch which turns 5v off or on - I turned it off and got the boot output - still don't know why it won't boot from nvme though
