Ux_DEVICE_HID_CDC_ACM example for the B_U585I-IOT02A

Moved from Feedback forum - the Feedback forum is just for questions about the forum itself.


Hello,

I have a problem with the Ux_DEVICE_HID_CDC_ACM example for the B_U585I-IOT02A. Basically, i cannot transmit anything due to an error with the initialization of the variable current_flags in the file tx_event_flags_get.c . what happens is that when you try and get the value of current_flags = group_ptr -> tx_event_flags_group_current, the value is always 0 and is never updated during the communication killing the transmission. Has this ever happened to anyone? how can i solve it? Thanks

Hi @jota_ber 
It seems I can reproduce the issue on my end. I can't get the serial device transmit or receive data from/to st link!
