Part Number:CC256XCQFN-EM
Tool/software: Linux
We're trying to use CC256XCQFN-EM with Picozed Zynq 7020 connected to a axi 16550 UART
It seems that the standard TI solution uses a pre-compiled Bluetopia stack, but for a number of reasons, we'd prefer to use the bluez stack.
From reading it seems that the hci_ii driver should work with CC256x, however, I must be missing a step and am looking for some help or ideas.
- the AXI UART is defined the FPGA and binds correctly to /dev/ttyS3
- The UART is configured for 115200 baud
- The bluez stack, utilities and tools all build and the bluetoothd launches fine
- The CONFIG_BT_HCIUART_LL is included, which should be the correct driver
I've tried then attaching the device using "hciattach /dev/ttyS3 texas 115200 flow" but just get an "Initialization timed out" error
I've alos tried using "any", but thats a different driver, and while it'll initialize, I'll get a number of other errors indicating that the hardware isn't support (a 95 and 110 I believe)
I'm assuming I'm missing something in the way that the bluez driver needs to attach to the UART.
It seems like just specifying "texas" doesn't let the hci_ii driver know the compatibility... which is to say which flavor of devices we're using.
Has anyone used a CC256x in this way?
Thanks for any insights.
