Hi!
An interesting device fell into my hands.
Manufacturer - Modas (https://www.modas.com)
Model - BWLC2 V11
This is Wireless-LAN bridge, for Bizerba Scales.
The device runs on a slightly modified OpenWRT. Since I have the device in my hands, I studied the hardware part, found the serial port, and would like to share this information by adding this device to ToH. But the problem is that such a manufacturer is not on the list 
The ToH is only for devices supported by mainline OpenWrt. Devices running OpenWrt derivatives, no matter how "slightly modified" or close to mainline they are, do not count.
Unless you're interested in porting official OpenWrt to this device, in which case we can help. And since you physically have the device on hand, you would be the most qualified person to do it.
Based on the picture from the site you linked, the WLAN card carries an AR9382, and the main board carries some NXP SoC I can't read from the picture. We do have existing devices that uses these chips, so porting shouldn't be extremely difficult.
The company appears to provide the GPL source code, so you can start with that.
I would be very happy to run the current branch of OpenWRT on this device, just out of interest and experience. But, unfortunately, my knowledge of Linux is slightly limited
From what I know, uboot has a wait time of 0 seconds. I tried to stop the loading 10 times, but it didn’t work. Currently the device is running on OpenWrt Chaos Calmer. I was able to install and run SSH, SFTP.
Here's some specification:

I tinkered with this device a little more. I found how to get into recovery mode. You need to hold down the reset button, and when the second LED from the button lights up red, release it. The device will enter recovery mode.

I downloaded the OpenWRT sources and kernel sources from the modas.com website to try to compile them and flash them onto the device. Just to make sure it works and understand the procedure.
Also, I extracted DTB from RAM.
After assembling the firmware from the sources, I received the "uImage" file (as I understand it, this is the kernel), as well as the following files (as I understand it, OpenWRT):
The bootloader in recovery mode asks for the files uImage (kernel), CpioRoot (RAMDisk image with RootFS?), and DTB.
I have a problem with CpioRoot. I tried to insert openwrt-imx6-rootfs.cpio - got such errors
Wrong Ramdisk Image Format
Ramdisk image is corrupt or invalid
At this point I have run out of ideas for now. Need community help

try running the bootm command in u-boot, and feed it one of the initramfs:es.

So
I tried to compile vanilla openwrt 21.01 and run it. I encountered the problem below. As I understand it, the system accesses the eMMC and does not find the root file system there.
