In upstream Linux kernel commit:
3a00da027946cd08db1c1be2de4620950bbdf074 ("tty: make tty_operations::send_xchar accept u8 char")
The prototype of tty_operations->send_xchar() was changed from:
void (*send_xchar)(struct tty_struct *tty, char ch);
to:
void (*send_xchar)(struct tty_struct *tty, u8 ch);
This commit was merged in Linux 6.8, and therefore the
ec_tty_send_xchar() implementation needs to be changed to avoid the
following build failure:
/home/autobuild/autobuild/instance-7/output-1/build/igh-ethercat-1.6.2/./tty/module.c:751:19: error: initialization of "void (*)(struct tty_struct *, u8)" {aka "void (*)(struct tty_struct *, unsigned char)"} from incompatible pointer type "void (*)(struct tty_struct *, char)" [-Werror=incompatible-pointer-types]
751 | .send_xchar = ec_tty_send_xchar,

vim700: spelllang=en spell Virtual TTY interface driver for EtherCAT slave supporting serial comm Quick installation guide: ./configure --with-linux-dir=/your/linux/directory --enable-tty make all modules make modules_install install rcethercat start insmod tty/ec_tty.ko insmod examples/tty/ec_tty_example.ko The default settings for the serial line are 9600 8 N 1. The tty example operates a Beckhoff EL6002 at ring position 1. For a short test, connect port X1 with a serial port via null modem cable. If a minicom is started on that port and the below command is entered, the output should be visible in minicom: echo "Hello World" > /dev/ttyEC0 Have a lot of fun!
