Novasom M7 PLUS EMMC boot problem


carlosinacio

Recommended Posts

Hello all,

 

I have a Novasom M7 Plus board with a Rockchip RK3328 that initially had an SD card with Armbian. I made the necessary hardware connections to connect to a screen via HDMI and then I followed all the necessary steps to perform the BOOT through the eMMc memory but after transferring the rootfs it will not start via EMMC, only with the SD card it is possible to start the system.

 

I have tried a lot of solutions that I am finding in the forums but I still haven't been able to solve the problem. The goal is to start Armbian without having the SD card inserted.

Board: Not on the list

How did you do the transfer ? Did you used "nand-sata-install" ?

I used the Armbian configuration utility. However I was experimenting with more solutions and think I messed up because I changed the boot section in ArmbianEvent.txt file to try boot from the eMMc memory but now the board doesn't boot and the LCD turns on but shows nothing and ends up shutting down..

 

Is there any way to format everything or put the board with the factory settings?

Are you still been able to boot from SD ?

In such case, you should be able to redo the process from scratch ...

If not, you will need to find a way to disable eMMC, usually using a jumper or a test point.

I can't boot from the SD card.

I connected the board to the computer and was able to read the boot logs.

 

"Found a dos partition table in /dev/mmcblk2
fsck exited with status code 8
done.
Warning: File system check failed but did not detect errors
mount: Invalid argument
Failed to mount /dev/mmcblk2 as root file system.
Rebooting automatically due to panic= boot argument"

 

As I expected the board tries to boot from mmcblk2 and that is why it gives an error. Can I change to boot from mmcblk1 or something else?

Maybe ... Can you try stopping U-Boot in early stage by pressing several times <spacebar> to get into the U-Boot prompt ?

If Yes, then do "mmc list" to figure out if SD is present, then "setenv devnum 0" (if 0 is the SD) followed by "run mmc_boot", it should then boot from the SD ...

I was able to solve the problem of installing Armbian in eMMc memory and boot the board without the SD card.

 

However, now I'm having problems connecting to Wi-Fi. I have a 2.4Ghz antenna connected to my board but only wired connections appear. I have already modified the interfaces file in the network folder but still not yet I managed to establish a Wi-Fi connection..

Never heard about about this brand ...

Maybe there is no Linux kernel driver for it ?

Is it a USB dongle ? What "lsusb" is showing ?

 

When I had Armbian installed by the company that supplies these boards, the WiFi antenna worked and I was able to connect to the WiFi networks. Did a driver already installed on purpose for this antenna?

 

It's not a USB dongle, I leave an image bellow.

The "lsusb" only show this:

 

magnumcap@NOVAsomM7:~$ sudo lsusb
Bus 005 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 004 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 002: ID 222a:0001

Ah ! But this is only an antenna...

What is the WiFi module part of the SBC, usually a small metal square module, what is the part number written on it ?

 

I think this board doesn't have a WiFi module because the antenna connects directly to the board..

Yeah, the part number is rtl872385

You mean RTL8723BS ...

Armbian has some patches for this drivers, but they are actually for some AllWinner boards, not for Rockchip.

It is possible to port them, but maybe it is an hard job ...

I'm already in contact with those responsible for these boards. Apparently they are going to launch a new version of software as the latter version doesn't seem to be able to activate WiFi.
