I am trying to bring up the bluetooth on the ultra96 V2 board.
When it is not working we see this UART time out message
> Bluetooth: hci0 command 0x1001 tx timeout
I found that only working case is without fpga image loaded (no bit file download, which is PYNQ image) and use FSBL (first stage boot loader) and U-boot from PYNQ, the rest, kernel/dtb/rfs are not related.
Here are my questions?
- can you confirm that if Bluetooth is working with official oob image, Ultra96 oob image http://avnet.me/ultra96-v2-oob , on Ultra96 v2 board?
- do you have any workaround or fix for this issue (provided that you confirmed this issue on Ultar96 v2 board)?
Thank you very much,
