Yes, the guides here in the forum, the wiki. And they all state you need a serial to usb adapter. That’s the guide. There is no other.
How thoughtful of them to not mention that a serial cable was a must-have accessory. Took two months to arrive from China to Argentina. I’ve spent nearly two more weeks pulling my hair out over this. Buying it upfront would have saved me the shipping fee and a ton of frustration.
Thanks for your support and have a great year
Happy New Year!
You can set up the installation as needed via SSH.
SD boot => SSH =>
fw_setenv bootcmd "env default bootcmd ; saveenv ; run ubi_init ; bootmenu 0"reboot
Wait until the installation to NAND completes, and the router boots from SD.
Turn off the router, switch the boot to NAND.
NAND boot => SSH =>
fw_setenv bootcmd "env default bootcmd ; saveenv ; run emmc_init ; bootmenu 0"reboot
Wait for the router to reboot. Turn off the router, switch to eMMC boot.
Boot from eMMC => profit
With UART access, it’s easier, and you can view logs in case of an error. However, this is not an essential tool, and it can be bypassed, although it’s an unusual option that doesn’t immediately come to mind for the user.
Aren’t there steps missing? You can’t install from SD to MMC, because as Frank mentioned, there is just one controller in the CPU. It’s either one or the other.
Doesn’t he need to switch to NAND boot after the first execution of your changes? As far as I understand them you switch the default uboot option to install, right?
So it’s SD boot, fw_env changes, SD boot (installs to NAND), NAND boot, fw_env changes, NAND boot (installs to eMMC), eMMC boot?
This 21.02 MTK SDK version, that comes with; is it the only one (as compared to openwrt.org’s snapshots) that lights up the 2G/5G/6G blue LEDs on BE14000 card?
Otherwise looks workable, and AC and AX speeds are good, but how to turn on EHT320 on the 6 GHz radio? Regardless what I try on /etc/config/wireless, iwinfo shows HT20 on rax0 radio. This with the 21.02 SDK version only - I can turn on EHT320 on the 24.10 snapshot versions.
Any help appreciated.
I would have gone on the 24.10, either rc4 or snapshot, but for some reason or another, it occasionally freezes my SSH connections on WLAN… and only the SSH connections. Plus the aforementioned LED weirdness.
For led i guess there is anything missing in driver which was added in sdk somewhere…looked through some of the patches there,but have not found something led-related
Maybe you can try if self compiling from this repo has also led support. Possibly bpi released image modified a bit.
For hang i have no idea…i guess it is an issue in dma handling,but only affecting ssh is strange…what have you tried? Ping,other tcp based protocol?
Yes, ping (which doesn’t count, as is either udp or icmp). Even for more weird, plain-old Telnet session doesn’t suffer at those times. Only SSH.
We really need to keep topics separate. Could you create a new one for this issue?

Could be some issue in encryption. If there 1 packet gets lost and not retransmitted by tcp (or broken again) it could break ssh.
@totkeks ack better 2 topics one for mt7996-led one for ssh hang there
Sorry about topic loaning. Didn’t have credentials to start my own.
You’re right. I mixed up the memory type when I wrote that, but not the commands.
run ubi_init installs to NAND,
run emmc_init installs to eMMC.
I corrected my message.
Just want to comment that finally I bought a cable Usb Ttl Ftdi Ft232rl locally and once have it installing the new images was a piece of cake.
As I said previously. How thoughtful of them to not mention that a serial cable was a must-have accessory and bought everithing in the same package.
Now I have the latest snapshot running from eMMC and some new problems arises (ETH ports stoped working, filesystem do not use all the eMMC space, ssh connection randomly gets disconnected, etc) But I will investigate and ask in another specific threads if needed. Thanks by your support
You seem to have completely forgotten one thing: It is and remains a developer and tinkering board. This means that various things can be assumed to be known and available. I hate people who don’t take the trouble to inform themselves in advance and think that they are getting a completely finished and ready-to-use product. People like that should just stick with the Fritzbox. It’s for end users, ready for immediate use and requires little or no knowledge.

Git pull this morning on openwrt’s repository and Mediatek patches, and voila, SSH woes are gone. 
Could you link to the commit? I tried to search through the most recent commits, but it’s really hard or impossible on a phone.
Is it possible that my WIFI card was burned with the latest sysupgrade?
I applied the latest sysupgrade and after the reboot it worked correctly for a few minutes and then hung. I connected via console and found that the boot (from eMMC) was interrupted. Assuming that there had been a problem with the upgrade I inserted the SD card with which I had installed the system and found that it hung at the same point.
I tried other images and found that they all interrupt the boot at the same point with the only exception of ubuntu but I could not find in the instructions the password with which the root user is configured.
This is the point at which the boot is interrupted. Can you think of something?

You can format log output using the “preformatted text” feature of editor here. That makes it much easier to read.
Also, did you press enter after connecting the console? This looks like the normal boot output on console. A login prompt only appears after you press enter.
This is the point where I feel extremely stupid 
Yes that was the problem about the boot stuck
Even that wifi still not starting and when I plug the eth cable from a laptop to get access to it ETH connection never starts
This is from serial console

Hi,
How did you manage to run the command and get it to work on an BP4?
I booted from openwrt’s openwrt-24.10.0-mediatek-filogic-bananapi_bpi-r4-sdcard.img.gz, and got this:
root@OpenWrt:~# fw_setenv bootcmd "env default bootcmd ; saveenv ; run ubi_init ; bootmenu 0"
Cannot parse config file '/etc/fw_env.config': No such file or directory
Failed to find NVMEM device

Sorry for the old post resurrection. You looked knowledgable
