Troubleshooting • Re: [BUG]Bookwoorm: Pi2 No UART possible on GPIO14/15

Dear Raspberry Pi Team,

it seems to be a long lasting problem with the serial.

wanted to activate the UART0 on 14/15 to be usable on Pi 2 for putty but did not get it to work.

Used

Code:

sudo raspi-config
to setup, but was not successful.

/boot/firmware/cmdline.txt looks like:

Code:

root=PARTUUID=7b325855-02 rootfstype=ext4 fsck.repair=yes rootwait quiet splash cfg80211.ieee80211_regdom=DE
And /boot/firmware/config.txt

Code:

[cm5]dtoverlay=dwc2,dr_mode=host[all]enable_uart=1[code]# disable bluetooth and bring back uart on GPIO 14/15dtoverlay=disable-bt

Code:

~ $ pinctrl get 14,1514: a0    -- | hi // GPIO14 = TXD015: a0    -- | hi // GPIO15 = RXD0
Is there any setting which have to be set?
