New ContributorDE10 communication with windows PC
Hi,
I must confess I'm using my own UART modules written from the scratch since many years, thus I didn't care for existing Quartus UART IP. Perhaps others want to add info about it.
Regarding UART over JTAG, I know there have been some projects, I looked upon it many years ago but didn't found it useful for my purposes. Instead I'm using other JTAG debug functions during development and initial PCA test along with UART based debug interfaces. Also remote debugging through Ethernet and custom interfaces.

New ContributorThank you for the answer.
On the host side, I assume there will be a com port assigned, so the access via software is easy.
Is that the same com port assigned to program the DE10 Lite?
I still have questions about the DE10 Lite side:
1- Can the UART IP that is part of Quartus be used for this purpose?
2- Would the communication to this UART will run on the USB connection that is used to program the DE10 Lite?
Thank you
Yigal
Super ContributorDE10 lite programmer hardware is copy of USB Blaster and has only JTAG functionality. It can be used for communication purposes e.g. through JTAG UART IP or other debug components like source & probe or in-system memory content editor. It requires Quartus JTAG stack components to be installed on the PC.
If you have the option to connect two FPGA pins to an USB UART, I'd prefer this option.

If you have the option to connect two FPGA pins to an USB UART, I'd prefer this option.The two FPGA pins are not an issue, I start to understand that implementing an internal UART is the solution - I opened a separate ticket for that - I am not sure how to to use the Quartus UART IP.
I sill miss something - if there is a UART over JTAG, wouldn't it be possible to use it?
