Hi,

 

My NanoPi M4 V2 Won't Boot via SD  ... the emmc is not installed on the board 

 

The RED light is ON but the GREEN stay OFF

I cannot reached to read correctly the data coming from the serial port debug (I tested with many bauderate, also with 1500000, same result ... a lot of weird characters)

 

Tested Versions Won't boot:

Armbian_22.08.1_Nanopim4v2_jammy_current_5.15.63.img.xz

Armbian_22.08.1_Nanopim4v2_bullseye_current_5.15.63.img.xz

Armbian_22.11.0-trunk_Nanopim4v2_sid_edge_6.0.3.img.xz

Armbian_22.11.0-trunk_Nanopim4v2_kinetic_edge_6.0.3.img.xz

 

Tested Version Boot properly:

Armbian_21.02.1_Nanopim4v2_buster_current_5.10.12.img.xz

 

I use a workbench power supply 5A ... with current limitation set to the max value

 

I tested many SD card (all are class 10)

 

What i'm doing wrong ?!

What could i verify ?

Any idea ?

 

Thanks guys

Also on the image that is working?

Strange. You sure you have V2, not V1? Perhaps some memory configuration that is not supported with mainline boot loader? RK3399 can be booted with open source or closed source loader. We changed to open source at some point, but not on all boards. Perhaps this is the issue?

 

We have a few of those acting as a build runners - no issues whatsoever:

I verified ... it's well a V2 ... but i noticed something weird, i only have  2 Go of RAM ... and in the output you shared you have 4 Go RAM, does it possible that my boot problem came from there ?!

Highly possible. Not all are capable of going higher then 115200

Like I said, unsupported memory chip in boot loader would explain those troubles. Probably it would work if you flash nonworking image with a u-boot from a working one. You can find them here: https://imola.armbian.com/apt/pool/main/l/linux-u-boot-nanopim4v2-current/

What is the seek and bs parameters values for the dd command to flash the .deb file into the SD card ? where can i find them ?

u-boot deb package contains a script for flashing. 

sudo dpkg -i linux-u-boot-current-nanopim4v2_21.02.3_arm64.deb 
(Reading database ... 81517 files and directories currently installed.)

I installed the package into my current system and ... boom ... the sd booted ... how does it possible, it's magic !! ... thanks dude

 

Ok, i said "Yesss" too quickly ... aftet the reboot, the system booted via the micro SD, i copied the sd content to emmc (via armbian-config tool) and after that, nothing boot anymore

 

I installed again "buster" version ... but this time, i will flash bootloader of SD card via armbian-config tool ...

I didn't say installing package will do the job  Explore .deb file. Flashing is purposefully manual - via armbian-config - if your system is up and working.

Hehe 😅

 

Ok, everythings works !

 

For people with same problem than mine, this is what i did

 

• Install u-boot Debian package,  one that you knows works (download via: https://imola.armbian.com/apt/pool/main/l/linux-u-boot-nanopim4v2-current/)

  dpkg -i linux-u-boot-current-nanopim4v2_xxxxxx_arm64.deb

• Launch armbian-config tool 

  sudo armbian-config
  System -> Install -> Install/update the bootloader SD/eMMC

• The SD is now bootable

Thx again to Igor for his help  🤜🤛
