SDI TX subsystem VTC

[skanarek]

Hello 

I am using SDI TX subsystem ( used the sdi rx subsystem @ zcu106 as ref. design ) on custom made board with US+ 9EG device.

when exporting the HW to SDK I can see the address map correctly assign of both sub cores  SDI TX and VTC at xparameters.h  , but while executing "configinit "at SDK the VTC is missing , Memory map also show "?????" at  Base address + 10000 as assigned for the VTC core .

sdi tx ss base adders is 0xa0000000 , so VTC should be at 0xa0010000 , but it is not . 

Thank you

HI @skanarek,

If the address is correct in xparameters.h, then it should also be correct in the code. Can you add some more detail to help us look into this?

• What version of the tools are you using?
• How are you checking "Memory map also show "?????" at  Base address + 10000 as assigned for the VTC core"? Can you add a screenshot?
• Do you have any errors when you build the project? 

Thank you,

Sam

Hi

I am using Vivado 2018.1 with Ubuntu 16.04 OS.

I have attached screenshot with SDK debug running  the SDI self test example .

No errors during project build.

SDI SS with all of it's sub cores are visible when viewing implemented schematics.

Thank you

Hi @shaikanarek,

As a double check to see if this is an issue with SDK/xsdb or the code itself, can you print out the values being pushed into the self-test function?

I will try to replicate this on my side on a similar setup.

Attached is the SdiTxSSinst which is pushed into the XV_SdiTxSs_SelfTest function.

Hi @shaikanarek,

I ran on my side using the passthrough example design from PG290 as hardware. For software, I used the TX self-test function and did not see any issues.

Please verify that your HDF is up to date and that your FPGA is using the correct bitstream.

Hi

can look into 0x80030000 ? 

base address that you are show is working fine on my design . the VTC is not....

The VTC address is mapped with offset of +0x0010000 to the base address of the SDI subsystem core .

Hi @shaikanarek,

I do not see any issues on my side with the VTC. My suggestion is that you step through the driver and see where you are getting stuck. 

Adding print statements may help as well. 

It sounds like your HDF does not match your bitstream.

Hi

I did a workaround  , implemented all the tx subsytem sub cores manually .

Thank you
