KNXD crashes with TPUART-USB-Light (NCN-ESP32 version)

[JackyKNX]

Hi,

I'm still having issues with knxd and the new TPUART-USB-Light (from busware.de).

Debian x64 and knxd updated yesterday to version 0.14.67.1

My knxd.conf:

KNXD_OPTS="--eibaddr=1.1.128 --client-addrs=1.1.30:8 -D -T -R -S -b tpuarts:/dev/knx1"

After a few seconds knxd crashes and reports send timeout and link down, also not being able to bring the link up:

I've attached full log file.

Anyone having same issue, any ideas how to solve?

thanks,

Something appears to be eating the data on the serial line. Are you sure that the system doesn't have ModemManager, or a serial console, or something else along these lines on the port?

[JackyKNX]

Hey, yes, I'm sure, no serial console enabled etc., I've also tested on Rasp3B with serial console disabled, same issues.

BTW, it works like a charm (not a single failure for a few years) with old TP-UART (ATMEGA)...

[JackyKNX]

I replicated the issue on freshly installed RPI (Raspbian 64bit), the same knxd version and configuration. Attached some additional logs:

Damn - i think i added a duplicated issue here: #595

pretty much looks similar to my problem.
