Openwrt trunk now officially supports the required 233 for Banana Pi BPI-R4 + BE14 Wifi module

frank-w · January 5, 2025, 2:10pm

No,mt7530 driver is involved for switch part

Ah, you are right. My bad.

I’ve not been using the MTK feeds for a while, OpenWRT runs stable from the 24.10 branch. But the documentation for that feed is outdated for they created a directory for the 24.10 branch that should be used instead of the main content.

I used the instructions for master (and replace the path with the 24.10 but I still have a limit of 6dbm and is unclear if this is not supported yet, some bug or even a different version of the board. I also checked the eeprom and is my understanding it loads the mt7996_eeprom_233_2i5i6i.bin and the MD5 matches the upstream / MTK version.

OpenWRT Issue wifi txpower value is very low · Issue #17489 · openwrt/openwrt · GitHub

Yeah, saw it later, the 24.10 content directory’s patches don’t apply on the 24.10 branch. Manually fixing the conflict, then building for ‘mt7988a-rfb’, with the new 233 firmware in OP, the bpi-r4 doesn’t boot. Not sure what happened, don’t have serial yet.

EDIT: Is there some place that builds these MTK SDK bpi-r4 images in a standardized manner? Frankly I don’t have time to figure out why somebody’s flaky patches don’t apply on the the branch they’re intended for. Currently, this feels like a waste of time, because each person will produce subtly different builds, and there’s zero point of reference.

@frank-w are you running a Banana Pi R4 with the the BE14?

frank-w · January 7, 2025, 6:03pm

I have be14 installed and did basic steps like starting hostapd,not more yet as i’m busy with different things.

And i work on mainline kernel in debian and not openwrt.

Cool, thanks for the update. Since I’m blocked with openwrt I may actually give a go to Debian.

I build an image using GitHub - frank-w/BPI-Router-Images and I get a similar limitation but this time I get an error message from the module

Tried 24.10.0-rc5 bananapi_bpi-r4-sdcard.img.gz. Dmesg: dmesg_bpi-r4_24.10-rc5.log.txt (93.8 KB) And BE at 320MHz works!

@SSIV Are you also able to set the tx_power to something more than 6/7 dBm?

SSIV · January 19, 2025, 1:38pm

Driver default is 23 dBm in JP region.
