Please provide some examples or applications using crossbar switch of MPC5643L.
In every example code it is used XBAR. It is just not configured as 99% of applications uses default XBAR configuration.
If you want some user specific XBAR configuration tell me the priority order or masters and slaves.
But XBAR is so simple that you can configure it in 5 mins yourself.
Master is eDMA and Slave is SRAM. How they will interact?
They will interact exactly as it is configured in your XBAR.
eDMA is master and will have accesses based on configured priority on SRAM slave.
Thanks for your reply. Since I am a fresher, I don’t know where to start, that’s why I post it as a question. I have no idea that it can be configured within 5 minutes.
Have a nice day.
You replied me that XBAR will be left with default settings. I understand the concept of XBAR. But I have no idea how to configure XBAR.
It has 4 masters and 3 slaves. Default settings means which master is assigned as highest priority. Whether any changes to be done in master and slave module registers. I am going to start with XBAR in MPC5643L as we are new to this controller. Can you tell me how to do?
As I was for some time out of office, expect that you have figured it out yourself. Now when you are familiar with XBAR it should not be any issue.
Just in case:
In master priority register you can configure priority of Masters on XBAR:
And debugger screen:
And slave port masters priority:
Let me know if you have additional questions.
Thanks for your answer. I understood the concept of CROSSBAR. I got familiar with this module.
