Hi,Everyone

I have a question.
I use EK-TM4C1294XL and Tivaware v2.1 with CCSV6.
I am trying usb_dev_cserial but it does not work.

I do not see data on Tera Term When I send data from another Tera Term Window to UART0 port
I watched interrupt if uart0 get receive data.
but data does not appear on Tera Term.

I already install SW-USB-WIN and I checked windows_drivers folders in Tivaware

Do you know how to get data?

Regards
Hiroyasu

Hello Hiroyasu

Can you check that if the memory window in the CCS is closed. Basically any view of the USB or some of the other system registers which are Clear on read can affect program flow in debug mode.
