Bluetooth issue

Postby thunders » Sat Dec 30, 2017 3:51 pm

Hi,

I'm currently building an image using yocto rocko for my wandboard REV C and I've got this error message when I load the bluetooth firmware :

brcm_patchram_plus -d --timeout=6.0 --patchram /lib/firmware/brcm/bcm4330.hcd --baudrate 3000000 --no2bytes --tosleep=2000 --enable_hci /dev/ttymxc2
option timeout with arg 6.0
option patchram with arg /lib/firmware/brcm/bcm4330.hcd
option baudrate with arg 3000000
option no2bytes
option tosleep with arg 2000
option enable_hci
/dev/ttymxc2
writing
01 03 0c 00
writing
01 03 0c 00
writing
01 03 0c 00
received 0
select() returned error, errno=4
writing
01 2e fc 00
Read timeout reading nof_bytes

Do you have any idea regarding what's happening and how to fix it ?

Thank you

It appears as if the BT chip is not responding to the firmware.
Usually this is a serial issue (did you enable hw flow control?) - or that you did not power up the BT properly (there are GPIOs controlling power to the chip).
