Hi,
I'm having trouble with NuttX on the ESP32S3 trying to get UART1
(configured on the default pins) working via /dev/ttyS1. The driver
code for esp32s3_serial.c seems to configure uart1 as /dev/ttys1 when
you enable it in the configs, however, testing via
serialblaster/serialrx (and our own custom app) doesn't seem to send or
receive anything on uart1. I've tried swapping my connections to the
pins, testing every pin on the devkit board with serialblaster and
nothing ever comes out. I don't have this problem on an esp32 devkit
(with either uart1 or uart2). It seems to only happen on the esp32s3
devkit. I can successfully use serialblaster/serialrx on /dev/ttyS0 and
see the output/enter text.
Is there something I'm missing?
Thanks,
-m
