Re: Pi3 UART stopped working? Read this.

Does it ever work if you manually start hciattach after the pi has booted? i.e. sudo systemctrl start hciuart? Your error seems to be coming from an unexpected reply to bcm43xx_reset in hciattach_bcm43xx.c which could perhaps be being caused by the device trying to connect as the HCI comes up. You'd...

Re: Pi3 UART stopped working? Read this.

Great. Its the same for me too - just enable_uart=1 isn't enough. Doesnt make sense though... as everything I have read says the mini uart is dependent only on core_freq and not arm_freq. I think it makes sense the settings are separate - as if a fixed baud really does also need a fixed arm freq the...

Re: Pi3 UART stopped working? Read this.

sorry to divert this thread back to the UART issue again. Having tried all the suggestions on this forum, I still get data corruption on any baud rates I try on the pi 3. I'd love to test the pi as a platform for the project I'm developing. Short of having a reliable serial connection (or any seria...

Re: Pi3 UART stopped working? Read this.

Hi,

Could anyone help with reliability issues I am having with the above solution where by 1 boot in every 5 or so, bluetooth on the miniuart will not respond but the other 4 boots works perfectly?

Full details viewtopic.php?f=28&t=148026

Many thanks

Pi3 UART and Bluetooth

I have an app that needs to make use of the PL011 UART connected to a modem. It also needs to make use of Bluetooth. I have configured the Pi to use the pi3-miniuart-bt overlay to move Bluetooth to the mini-UART. I have updated hciattach.service to use /dev/ttyS0. I have removed the attachment to th...
