Hi,
Every bitfile that has uart, loaded fails with the following message:
"hm2/hm2_7i80.0: inconsistent Module Descriptor for UART Transmit Channel, not loading driver"

7i80 firmware is: 7i80hd_25_svua8_4.bit

Test file:

loadrt trivkins
loadrt motmod servo_period_nsec=1000000
loadrt hostmot2
loadrt hm2_eth board_ip="192.168.1.121" config=" num_encoders=2"

Test by halrun:

What might be the problem? Does the uart only work with an existing daughter card?

Thanks

hi,
I want a simple RS232 interface that communicates with my own hardware (ATXmega).

you shoudt use a USB-rs232 extension and workout your own comp to get what you want out and in to the system

like most use for Hyanyang VFD
there is a component that uses this
also the XHC component uses Rs232 connection

What configuration do you need?
If you are using 7I80 configuration from the zip file they are pretty old and may have bugs

Thanks for the tip. it would be nice to handle communication in real time. Maybe there will be a solution :)

Hi Peter,
8 stepgens, 4 encoders, 1 pwm and simple uart rx-tx without protocol signals.

Note that there is a UART bug in the LinuxCNC driver :-(

forum.linuxcnc.org/27-driver-boards/3711...nc2-8?start=0#141396

I will push the fix in the next few days. It isn't new n 2.8, but might have managed to work with a single UART despite the bug depending on the details of the compilation......
