Bluetooth issue with 1DX Murata module

Question

Hello everybody,

I'm trying to enable Wi-Fi & Bluetooth connectivity to the ZedBoard, using the 1DX Wi-Fi/BT module (LBEE5KL1DX-883)

A complete tutorial has already been done here: Adding Wi-Fi and Bluetooth Connectivity to the ZedBoard using the Murata 1DX Pmod

I succeeded in enabling Wi-Fi, but I'm facing a persistent issue when I try to enable Bluetooth.

I'm using the Harware design provided here (Reference designs section): https://www.avnet.com/wps/portal/us/products/avnet-boards/avnet-board-families/zedboard/

Here is the script I run to enable Bluetooth:

And here is the issue (bluetooth LED is turned ON when the script is launched):

Is somebody able to know where I should go to fix this issue concerning hciattach?

Regards

Update: It's working, and it was exactly what I thought : if you want ttyS0 to appear you have to make sure the UART IP block is recognized. The problem is that it's not documented at all: UART 16550 IP block needs some options available with petalinux-config -c kernel: - 8250/16550 and compatible serial support - Support 8250_core.* kernel options - DMA support for 16550 compatible UART controllers - Devicetree base probing for 8250 ports - Cadence (Xilinx Zynq) UART support - Cadence UART console support And then the hciattach function does not return any time out, and Bluetooth pairing works fine. Thank you bhfletcher for your precious help!

That is great news! Thank you 3d_srv for sharing these valuable findings with the community! For anyone else that is interested in experimenting with the Murata 1DX Wi-Fi, this is the same radio that is native on the AES-MINIZED-7Z007-G MiniZed. Or you have the option of adding the AES-PMOD-MUR-1DX-G Pmod to any Pmod-capable board. Bryan Murata 1DX Pmod Murata 1DX Pmod MiniZed with Murata 1DX Radio MiniZed with Murata 1DX Radio
