TMS320F28388D: Example "can_ex5_transmit_receive" sometimes stuck in "CAN_initRAM" sometimes not

Hi Sheldon,

Can you help us understanding the conditions in which you are facing this issue? Like any particular sequences of execution or any particular Transmitter-Reciever communication configurations, etc.?

Hi Praveen,

1. When this issue happens, only power off the board can we make the original example code running well. Reset target from CCS does not help, 

2. This issue occurs randomly, but easy to reproduce, I dind't have a conclusion on how to reproduce. You just need to run it CPU1.

Thanks

Sheldon

Hi Praveen,

PS: this issue only happens when on-board debugger is attached. When boot from flash, this will never happens.

Thanks

Sheldon,

If it is clearly happening only with the debugger connected, can you give us little more detail on what is happening on the debugger interface before the issue is happening? Do you have any debugger windows reading any memories/variables in refresh mode?

Also, have you done any changes to the example? If so, can you share the modifications as well?

Regards,
Praveen

Hi Praveen,

We have priority for this issue now. I will close it first. When I have time I will work on how to reproduce this issue. It seems highly related to the debugger connected to device.

Thanks

Sheldon
