Fail on to build AW697 kernel module

ChChang — Fri, 05 Jan 2024 14:30:24 GMT

I am currently trying to build the AW697 driver into a kernel module for use on Android 13 running on an i.mx8mp-evk.
However, as I am not yet familiar with Android, it seems that my execution method is incorrect and I am encountering the following error messages. Could you advise on the correct way to build this kernel module?

Did you check page https://www.nxp.com/design/design-center/software/embedded-software/i-mx-software/android-os-for-i-mx-applications-processors:IMXANDROID ?

Ex for "Android 13.0.0_1.2.0 (L5.15.71_2.2.0 BSP)" : see doc NXP Wi-Fi Driver Features and Release Notes for Android, in chapter "2 Getting Latest Wireless Driver and Firmware Fixes" : "For downloading the Wi-Fi driver...."

Re: Fail on to build AW697 kernel module

ChChang — Tue, 16 Jan 2024 10:45:12 GMT

I referred to /vendor/nxp-opensource/nxp-mwifiex and similarly added the AW693 driver to /nxp-opensource/.
Now, the Wi-Fi functionality is working normally on the i.mx8mp evk with Android 13.
However, the Bluetooth functionality is not responding at all.
What else do I need to modify? Thanks!

Attachment is my complete booting log,

Do I need to change the UART name?
If so, what should be the name for the AW693 Bluetooth to use?
And what files need to be modified ?
Thanks!

I think you need to follow doc https://www.nxp.com/webapp/sps/download/license.jsp?colCode=Android_Vendor_HAL_V009_Integration_Guide&appType=file1&DOWNLOAD_ID=null to integrate properly wifi and bluetooth BSP and device drivers.

Re: Fail on to build AW697 kernel module

ChChang — Thu, 18 Jan 2024 12:19:47 GMT

Hi

When I connect the AW693 EVB to the i.mx8mp-evk (Android 13),
/dev/ttyUSB0 is not generated. I checked the imx_v8_android_defconfig,
and it contains:

CONFIG_USB_SERIAL=y CONFIG_USB_SERIAL_CONSOLE=y CONFIG_USB_SERIAL_GENERIC=y CONFIG_USB_SERIAL_SIMPLE=y CONFIG_USB_SERIAL_CP210X=m CONFIG_USB_SERIAL_FTDI_SIO=y

So, the driver should also be enabled in the kernel. Am I missing any steps?

P.S. When connecting the AW693 to the i.mx8mp-evk (Linux),
/dev/ttyUSB0 is generated as expected.

Regards,

cdoumenc — Thu, 18 Jan 2024 16:10:35 GMT

In your case i.mx8mp, using Android, I think that you should see /dev/ttymxc0 according to conf/nxp/evk_8mp/bt_vendor.conf content :

mchar_port = /dev/ttymxc0

As doc "AN - 88Q9098-88W9098 - Android Vendor HAL v009 Integration Guide" I previously mentioned says, you can also change conf/nxp/evk_8mp/bt_vendor.conf to get :

mchar_port = /dev/ttyUSB

if you want.

Re: Fail on to build AW697 kernel module

ChChang — Wed, 24 Jan 2024 18:36:59 GMT

Thank you for your reply.
I have modified the contents of bt_vendor.conf as follows:
mchar_port = /dev/ttyUSB0
pFileName_image = /vendor/firmware/uartaw693_bt.bin.se
baudrate_dl_helper = 115200
baudrate_dl_image = 3000000
iSecondBaudrate = 0
baudrate_fw_init = 115200
baudrate_bt = 3000000
enable_download_fw=0

During the boot process,
I can see that the loading of AW693 fw pcieuartaw693_combo.bin.se is successful, and it shows WLAN active.

However, in Android, only WiFi is working, while Bluetooth is OFF, and even if enabled, there is no response.

Re: Fail on to build AW697 kernel module

cdoumenc — Thu, 25 Jan 2024 11:45:56 GMT

Could you provide logs please ? Especially showing what you observed ("loading of AW693 fw pcieuartaw693_combo.bin.se is successful", "WLAN active").

For BT : can you show how you see that "Bluetooth is OFF" and also that "there is no response".

Did you follow the integration guide chapter "2.1.1 Configurations Detail" ?
How did you set is_uart_port ?

Could you also check doc Getting Started with NXP-based Wireless Modules on i.MX 8M Quad EVK Running Android 13 OS – User manual, please ? Especially chapter "11 Debug of Bluetooth" to figure out what is happening.

Could you also check driver and fw versions in the output of command "adb logcat" ?

In the Android settings page, I can see that Bluetooth (BT) is off.
Bluetooth off

I clicked on the Bluetooth button to try and enable BT, but the status remains continuously in 'Turning on'.
Try to enable BT

I followed your instructions to check the logcat and found 'open uart port /dev/ttyUSB0 failed'. I think this should be the main reason.

I understand that, in file bt_vendor.conf, you didn't set is_uart_port, so, according to doc "AN - 88Q9098-88W9098 - Android Vendor HAL v009 Integration Guide", it is set to defaut value 0, ie "Use SD or USB interface".
Could you set it to 1, ie "Use UART interface", please ?

Re: Fail on to build AW697 kernel module

ChChang — Mon, 29 Jan 2024 18:52:53 GMT

Hi

Thanks for your reply!

In the previous log,
when the i.mx8mp shows the error message "open uart port /dev/ttyUSB0 failed",
I have already set "is_uart_port = 1" in the bt_vendor.conf .
The complete content of the file is as below:

mchar_port = /dev/ttyUSB0
is_uart_port = 1
pFileName_helper = /vendor/firmware/mrvl/helper_uart_3000000.bin
pFileName_image = /vendor/firmware/uart8997_bt_v4.bin
baudrate_dl_helper = 115200
baudrate_bt = 300000
baudrate_dl_image = 300000
iSecondBaudrate = 0
baudrate_fw_init = 115200
enable_download_fw=0

Are there any other part that need to be modified?

Regards,

Why

pFileName_image = /vendor/firmware/uart8997_bt_v4.bin
and not

pFileName_image = /vendor/firmware/uartaw693_bt.bin.se

anymore ?

I see in your last log 20240129-aw693.txt :

So you are trying to use Android 14 which NXP doesn't officially support. Could you use one of the officially supported Android releases for i.MX8MPlus please (ex : Android 13.0.0_2.0.0 (L6.1.22_2.0.0 BSP)) ?
You will find it on dedicated page https://www.nxp.com/design/design-center/software/embedded-software/i-mx-software/android-os-for-i-mx-applications-processors:IMXANDROID

Hi

I once set pFileName_image to /vendor/firmware/uartaw693_bt.bin.se, but it did not successfully enable BT, and since enable_download_fw=0, I thought the setting of pFileName_image was not important. I will correct it back to /vendor/firmware/uartaw693_bt.bin.se and try again.

Additionally, I downloaded the Android source from the NXP official website:
imx-android-13.0.0_2.2.0.tar.gz.
I don't know why the compiled Android version is
Linux version 6.1.25-android14-11-gaa4fe52ab59e-ab10687853 (build-user@build-host) (Android (10087095, +pgo, +bolt, +lto, -mlgo, based on r487747c) clang version 17.0.2 (https://android.googlesource.com/toolchain/llvm-project d9f89f4d16663d5012e5c09495f3b30ece3d2362), LLD 17.0.2) #1 SMP PREEMPT Mon Aug 21 11:40:17 UTC 2023.

I will download imx-android-13.0.0_2.0.0.tar.gz again and re-execute it to see what happens.
Thanks.

I have downloaded imx-android-13.0.0_2.0.0.tar.gz and comiler again ,

But the version still is Android14 not Android 13:
[ 0.000000][ T0] Booting Linux on physical CPU 0x0000000000 [0x410fd034]

I followed the "Android User's Guide Rev. android-13.0.0_2.0.0 — 31 July 2023" to execute.
Could you please tell me which step I did wrong?
Thank you!

Hi,

It seems that you didn't flash the built images to the target. Did you follow doc chapter "5 Programming Images" ?

Hi

I did a testing, I downloaded the i.mx8mp-evk demo images from the NXP official website, specifically android-12.0.0_1.0.0_image_8mpevk.tar.gz and android-13.0.0_2.0.0_image_8mpevk.tar.gz.
I then flashed them onto the eMMC in turn. For the complete log, please refer to the attachment.
It was observed that after successfully flashing the android-12.0.0_1.0.0_image_8mpevk.tar.gz, the version was as follows:

evk_8mp:/ $ cat /proc/version

After successfully flashing the android-13.0.0_2.0.0_image_8mpevk.tar.gz, the version was:

Please assist in confirming this. Thank you!

Hi,

Do you see BT working on your i.Mx 8M Plus after having flashed prebuilt images as explained in "Android 13.0.0_2.0.0 (L6.1.22_2.0.0 BSP)" doc ANDROID_QUICK_START_GUIDE.pdf at chapter "5.3 Flashing board images" ?

Dear @ChChang ,

I noticed the original question in the post is "Failed to build AW693 driver ", According to discussions from context, the question has been solved. And your another questions is on Bluetooth, so would you please help to create a new case or post for it?

[Note]

In order to avoid being confused, we usually discuss only one question in a case or post.

Thanks for your understanding!
