Radxa E25 support

maurer · February 24, 2024, 1:13pm

Radxa E25 is a network application carrier board for ROCK3 Compute Module Industrial(CM3I). It is somewhat similar to Friendlyelec's Nanopi R5c.

Features

Based on CM3I(RK3568 based, 4x A55@2Ghz, Mali G52 GPU, 0.8T NPU)
Dual 2.5G ethernet
Support mini PCIe WiFi cards(PCIe 2.0)
Support M.2 2242 SATA SSD
Support M.2 B Key 4G LTE cellular module
Support mini PCIe 5G cellular module
One nano sim card slot
One uSD card slot
One USB 3.0 OTG
One USB type C for power and serial console
16x RGB LED for status indication
One button for user control

As it was already supported on linux mainline since v6.3 I've added openwrt support in my branch maurerr/openwrt at radxa-e25 (github.com)

compiled builds (both ext4 and sqashfs) - https://oshi.at/KzkU - select one - extract the img and burn it on a uSD card (tested) or on the eMMC (untested)
kernel modules (if needed) - https://oshi.at/dtrV
imagebuilder - https://oshi.at/BvBT

Links should be available for 90 days - hopefully by then the support will be merged in main branch.
I’ll need to reformat the commits/description before I send the PR (hopefully next week) so I'm here asking community feedback.

thanks !

@maurer tried booting your image, according to serial console the boot starts but at some point serial console on usb-c port starts pumping gibberish, as far as I understand it gets disabled? My E25 has both 2.5G ethernet ports burned, seemingly functional otherwise, and I can't investigate further...

mr is rockchip: add Radxa E25 support by maurerr · Pull Request #14740 · openwrt/openwrt (github.com)
gibberish because console needs 1500000 bps - or maybe I've set the console for my builds at 115200 because 1.5m wasn't working for me - one or the other anyway thanks for trying it out !

DIYprojectz · March 11, 2024, 3:13pm

Thank you!

Indeed, changing baud rate to 1500000 allowed me to access the device, it booted fine and allowed me to set password. Radxa documentation suggested 115200, so that's what I initially went.
