Hello,

I’ve just purchased an TL-WN722N WiFi dongle. when i try to follow the provided documentation to build the WiFi driver.

i stuck during make.

i opened the make file and found the following platforms. which on i should use !
i tried CONFIG_PLATFORM_TEGRA3_CARDHU, CONFIG_PLATFORM_TEGRA4_DALMORE but both of them give me errors.

CONFIG_PLATFORM_I386_PC = y
CONFIG_PLATFORM_BCM2709 = n

Tegra3 (Cardhu) and Tegra4 (Dalmore) are very old Tegra systems. Those are 32-bit arm32/armhf/ARMv7, while Xavier is 64-bit arm64/aarch64/ARMv8-a. If there was a driver way back then for that adapter, then chances are it exists now in the stock kernel source. It would be a case of finding out what driver that is and configuring it to build as a module.

FYI, Xavier is the t19x series SoC, and specifically the t194. There may be some parts with backwards compatible drivers for the TX1 (t210) or TX2 (t186).

I don’t have this and tend to stay away from wireless, but some internet searching makes me think this uses the ath9k and ath9k_htc drivers (which should exist in the current source code).

FYI, if you have used JetPack or command line flash, then you will have file “Linux_for_Tegra/source_sync.sh”. Assuming your Xavier is R31.1, then you could download this source via:

./source_sync.sh -k tegra-l4t-r31.1

If you go to your current running Xavier, then save a copy of this file somewhere for safe keeping and as a starting point whenever you build a module for it:

/proc/config.gz

Also note the “uname -r” output. If the output is “4.9.108-tegra”, then the only thing needed to make that config.gz an exact match for a starting point in building modules (other than gunzip) is to set CONFIG_LOCALVERSION to “-tegra”. This is a substitute to any “_defconfig” step and is a better starting point.

Official docs exist for cross compile, just ask though if you need help for cross compile or native compile (native works fine, and a copy of the source_sync.sh script to the Xavier also works to download source there).
