Smart Lynq Cable HW_Server version flexibility?

Jump to solution

I would like to know if its possible to change the HW_Server version running the Smart Lynq Cable to an older version (2014.4)? or newer?

Details:

We have a wide range of products ranging from older Vivado (2014.2) based designs to newer (2018.1). The Smart Lynq cable is a great ethernet based JTAG solution and we would like to deploy it on all of our lab stations but we would need it to support not just our newer as well as our older cards. Another forum mentioned that:

"Basically, the rule is that the HW Manager (actually the hw_server process) does not talk to any Vivado/SDK that is newer than itself."

However when we try to connect an older 2014.4 HW_Manager to a newer 2017.3 HW_Server (running on Smart Lynq), we get a version mismatch error.

Also what is the latest supported HW_Server version for the Smart Lynq? Can we upgrade/downgrade firmware on demand?

 

Thanks,

Vincent

Hi @vincent.ibanez,

In the case of the SmartLynq cable, its firmware must be exactly on the same version as the hw_server that it's getting connected to.

You can easily upgrade/downgrade the firmware by running connetcing the Smartlynq to the HW Manager that you want to connect to, and then running the command:

update_hw_firmware -reset

Obs.: After updating the fimware you may need to cycle power on the SmartLynq and disconnect the USB cable.

You will only be able to downgrade the SmartLynq cable up to 2017.2. Before that, the cable did not exist, so there's no firmware that makes it compatible with older versions (so you will not be able to connect it to a Vivado / HW Manager 2014.4).

Thanks,

Thanks Andre for that information. I was able to connect 2016.1 HW_Manager to 2017.3 HW_Server but I can understand if the official stance is to match the version of the HW_Manager to the HW_Server.

@anunesgu  just for completeness : I found this AR, looks like it can be used with older versions? Or at least updated from? 

AR# 71624 - SmartLynq: Instructions for updating SmartLynq Data Cable firmware from 2017.2 or older to 2018.3

Hi @ronnywebers,

 

Yes, you can downgrade the firmware in the Smartlynq to support any older Vivado version up to 2017.2. Before that, the Smarlynq didn't exist, so there will be no firmware to downgrade to.

The upgrade is also true. From 2017.2 and newer, all Vivado versions come with the Smartlynq firmware, so you can follow the procedure in the AR to upgrade it.

Thanks,

ok so with firmware version 2017.2, the SmartLynq does still work with for example 2015.4, but there's no need to 'downgrade it further', all the older versions just see a 'basic JTAG' cable?

Hi @ronnywebers ,

I apologize for the confusion.

No, Smartlynq will only work with Vivado 2017.2 and newer.

It will not work with any older version.

Thanks,

@anunesgu  my confusion then probably comes from the title of the AR:

AR# 71624
SmartLynq: Instructions for updating SmartLynq Data Cable firmware from 2017.2 or older to 2018.3

So ... the 'or older' should be removed from that title?
