Hi RodolfoG_11

Can you please provide details on how was this component tested, which PHY device and the interfacing circuitry?

regards,

Vinay

Vinay,

We have internally tested using our own tools/hardware. Both sides (Host and Slave) were Cypress implementation to confirm that the MDIO interface spec was followed.

However, we already have many customers using this component, which was validated using PHY devices.

hi Rodolfo,

I am one of your Cypress sales reps.  I have a customer that wants to use PSOC6 in a CFP like module.  Could you please confirm that AN83902 contains the PSOC6 implementation for host & slave MDIO interface?  Also, would you use Modus toolbox or creator to implement? Thanks!

Employee

Hi John,

The AN83902 has the implementation of the Host and Slave MDIO Interface for PSoC 6, but only in Basic mode. Ideally, you want to use PSoC Creator, however, there are some hooks we can do to work with ModusToolbox. The component uses UDBs, so you have to use the PSoC 6-1M family.

Hi Rodolfo,

Do you have plans to implement the advance mode as well?

Also, can you please explain the hooks required to work make this work with ModusToolbox?

thanks,

Suresh

Hi Suresh,

Yes, we are in discussion to implement the MDIO Advance Mode in PSoC 6.

I see two ways to do this:

1) Use the steps provided in this blog:

https://forum.onethinx.com/t/how-to-use-udb-components-on-psoc6/365

2) Or we can create a library to wrap the UDB configuration, as we did for the SDIO driver for ModusToolbox.

Hello Rodolfo,

Thanks for your links.

Hello Rodolfo,

When I try to port this project using UDB porting tool (@oneThinx), I see I get only the PhyAddr_CtrlReg component getting ported and the MDIO interface, host, UART do not get ported. Did I miss anything here? Please guide me if this is not the right forum to discuss UDB porting issues.

Below is the OneThinx log:

Project Loaded: Example1_P6

The following components are found:

The UART in the AN83902_P6.zip does not use UDBs. It uses the fixed function SCB block.
