Build fails on CM3588 board (RockChip RK3588 based ARM board) with Debian Bookworm for a TP-Link T2U Nano (rtl8811au)

[agusventuri]

Hi!

I'm trying to build drivers for a TP-Link t2u nano adapter that has the rtl8811au chipset but can't get it to work. I'm guessing the Debian version I'm using has modifications that make it incompatible.
Here are some logs and info about the setup I have and the output I'm getting.

Hardware

• CM3588 NAS Kit
• TP-Link Archer T2U Nano

Issue

When executing the install-driver.sh it fails. Here's the result:

root@CM3588-Plus:~# ./install-driver.sh

Exploring the logs this is what I'm getting:

I tried several things, including modifying the c files myself, but I'm out of my depth there. If there's anything else you need from logs or output please let me know.

Hi @agusventuri

It probably would not take me too long to track that problem down but I'd prefer that you try a different driver:

https://github.com/lwfinger/rtw88

That is a driver that we are using for testing and the patching go upstream into the Linux kernel. In fact, the rtl8821/11au driver went into kernel 6.13. More patches to improve a few things will go into kernel 6.14. However, that repo has all work. We need it tested to see if any additional work needs to be done.

With my driver that you were trying to install:

$ make clean
$ sudo sh remove-driver.sh

That will clean things up and you can go to the rtw88 repo and give it a shot.

[agusventuri]

Hi @morrownr . Thanks for the quick reply.

I removed your driver and tried with the rtw88 but couldn't get it to work. The driver builds correctly but can't make it work beyond that.
I'm guessing then this FAQ applies: https://github.com/lwfinger/rtw88?tab=readme-ov-file#q1-my-driver-builds-and-loads-correctly-but-fails-to-work-properly-can-you-help-me and I should not post a new issue in the rtw88 repo.

@agusventuri

I'm guessing then this FAQ applies:

No, it no longer applies. I'll try to fix that today. The original owner of the repo wrote that but it really does not apply anymore so please post an issue giving as much detail as you think will help figure out the problem.
