There are two version of Nano PC T4 with different models of WIFI / Bluetooth CHIP

ihipop · December 25, 2024 at 9:54 AM

The old one USE AP6356S both the WIFI and Bluetooth work well with LibreELEC official images

currently, there are only new boards for selling

they mark the wifi chip with read font to emphasize the difference

any plan to support this?

PS: AP6398S uses bcm4359, which is already supported by the Linux kernel

I'm happy to backport merged patches to our current kernel(s). I'm not interested in adding unmerged stale patches that nobody is working to upstream. I suggest you build an image with the RFC changes, and if they work (or don't) comment on the mailing list thread to revive it and perhaps trigger some activity with the developers.

I've tried , And I encountered the same problem as the patch author of this https://patchwork.kernel.org/project/linux-…588f83@free.fr/

I don't know whether it's a DTS specification problem or not

it's beyond my knowledge

**chewitt** · December 26, 2024 at 7:57 AM

There are multiple issues being flagged in that thread, and some of them are likely due to silicon bugs in Amlogic hardware. So hard to comment on anything, and you share no logs, so ..

and also we didn't have brcmfmac43751-sdio but it seems not the problem right now

according to this commit https://github.com/StreamUnlimite…d_config.c#L224

for ap6398sv:

- the Chip ID is BCM43752_CHIP_ID

- the Devce ID is BCM43751_CHIP_ID
