The BT HAL version v009 crashes on the 88W8997 Wi-Fi chipset.

Hello Team,

I am working with the 88W8997 Wi-Fi chipset and I need to update my BT HAL code.

I have downloaded the "Vendor HAL v009" code from
https://www.nxp.com/webapp/sps/download/license.jsp?colCode=VENDOR_HAL_009&appType=file1&DOWNLOAD_ID...

The original content is located in the atv_s_9344727/vendor/marvell/wireless/bt/libbt directory.
~/atv_s_9344727/vendor/marvell/wireless/bt/libbt $ ls
Android.mk bt_vendor_mrvl.c bt_vendor_mrvl.h conf fw_loader_uart.c fw_loader_uart.h readme

To update the BT HAL code, I followed this commands:

$ cp -rf ~/NXP/Vendor_HAL_009/Vendor_HAL/LibBt-Hal-M009.005-src/android_Q/wireless/bt/libbt/* ~/atv_s_9344727/vendor/marvell/wireless/bt/libbt/

After updating the BT HAL code, the new content is in the atv_s_9344727/vendor/marvell/wireless/bt/libbt directory.

~/atv_s_9344727/vendor/marvell/wireless/bt/libbt $ ls
Android.mk bt_vendor_nxp.h fw_loader_io.c fw_loader_uart.c fw_loader_uart_v2.c hardware_nxp.c NOTICE
bt_vendor_nxp.c conf fw_loader_io.h fw_loader_uart.h fw_loader_uart_v2.h MODULE_LICENSE_APACHE2 readme

Subsequently, I built the Android code and flashed it onto the board. However, after the board boots up, the BT component crashes, and I have attached the logs.

Could you please assist in resolving this issue?

Wi-Fi chipset: 88W8997
