Hi,
I'm currently working with the IMX8MP processor from NXP and with M2-JODY-W3 module based on the NXP 88W9098 chipset. The M2-JODY-W3 module is configured to use PCIe interface for Wi-Fi and the UART interface for bluetooth, which are the default settings.
To use the M2-JODY-W3 module, I followed an NXP tutorial that outlines how to load the bluetooth NXP driver (btnxpuart) into the Linux kernel version 6.1.22 on the IMX8MP processor. After following this tutorial, I encountered issues with bluetooth communication, particularly during the driver loading process.
To troubleshoot this problem, I conducted a test by attempting to send the letter "A" to the bluetooth module. I observed that the IMX8MP RTS line cannot be grounded, which I suspect may be the reason why I'm encountering bluetooth communications issues. The test results are shown in the attached image, and the test was conducted after loading Wi-Fi drivers (mlan/moal) and the corresponding firmware (pcieuart9098_combo_v1.bin).
Could anyone help me with this problem?
Regards,
Simão Leite
