Hello el.ign,

I am the distributor embedded specialist who is following on the customer.

Regarding your line above, quoting:

"As mentioned the guide demonstrated the Uboot to be loaded from Ds-5, and shows it is semihosted."

Well, I believe the clame for semihosted uboot is a mistake:

If you go the section 5. ("configure the terminal settings") of the link you shared (https://rocketboards.org/foswiki/Documentation/LoadingUBootFromDS5),

you can notice the terminal setting are for REAL serial port and not a JTAG port.

The customer is looking for a way to make to u-boot print messages to the jtag port exactly as it is available for the preloader,

and simlarly to what is demonstrated in the following link for Arria10SoC:
