Hyperlink c6678 example asymmetric token exchange

Ahmed ElShaarany

Hi, 

In the hyperlink example, it is mentioned that in token exchange, a token (sequence number) is passed symmetrically between the two devices. Does symmetrically here mean that core x on the first board only exchanges tokens with core x on the second board ? where x= 0,1,2,...7.

If that is the case, what needs to be changed in the example to have, for instance, core 0 on one board exchanging tokens with core 1 on the second board (i.e. having different cores on different boards exchanging tokens)?

Thanks!

    Hi,

    Token exchange and block transfer are just our code examples for validate the hyperlink transfer, you can choose by your usage or write you own code for transfer. In Token exchange mode, pass one "token" by writing to the "write" address then attempting to read the same value back via the "read" address.

    Refer section "2.7.4 Address Translation" on Hyperlink user guide for more information(SPRUGW8C).

    Thanks,
