Setting Up Eclypse z7

[atown622]

How do you log into the ECLYPSE Z7 and set the baud rate?  Having troubles finding any examples on how to do this.  I have the username and password to log in the first time. Just not sure how to actually get there.

The baud rate is 115200 by default in all projects Digilent has released - this was previously omitted and is now specified in the demo documentation. The username and password are only required if using the PetaLinux image and associated demos, but you can find instructions for setting up either those projects or the baremetal ones here:

• https://digilent.com/reference/programmable-logic/eclypse-z7/demos/zmod-awg
• https://digilent.com/reference/programmable-logic/eclypse-z7/demos/zmod-scope

The baud rate is typically specified in the Vivado project's Zynq PS configuration. It may be possible to change from software through the use of some configuration register associated with the PS UART core, however, I haven't verified that this is the case.

Thanks,

"It may be possible to change from software through the use of some configuration register associated with the PS UART core"

Indeed it is. See the following link: https://forum.digilent.com/topic/22512-manipulate-pl-logic-using-ps-registers/

Be aware that, inexplicably, The tools ( at least the SDK for 2019.1 and earlier ) are limited to 115200 baud, which might complicate debugging, using the terminal console in the software GUI tools. A workaround, if you want to do 921600 baud is to use a separate UART terminal program such as Putty to interact with your hardware. 921600 is the highest baud rate that such programs can do without hardware flow control. For the Z7020 10 Mbaud is the upper limit and is useful as described in the tutorial. NOTE: the tutorial uses the standalone Xilinx OS. For those running Linux you'll have to work out how to access the PS UART registers. Direct access is highly discouraged in this case. But the general principal is still valid. PS UART FIFOs are fairly shallow, negating to an extent the benefits of using a high baud rate for some applications.

Trying out the tutorial is pretty straight-forward and easy so worth the time to explore. Edited June 6, 2022 by zygot
