AM2634: Multicore example project for AM263x_CC

MCU-PLUS-SDK-AM263X: How to debug and start a multi core project?

Hi,

Running SDK 09.01.00.41 and try to run example ipc_notify_echo for four kernels on a AM263x launchPAD lab card.

Running other examples with only one kernel works!

The result is strange can't get anything out on console and some of kernels starts in running. only way to start in suspend for all kernels is to switch power of before download, reset doesn't help.

We start each kernel in order R5_3,R5_2,R5_1 and R5_0. 

Nothing out on console 

After 10 seconds is  R5_3,2,1 kernels ending up in abort

We have tried with two different installations of SDK and two launchPAD cards with same result.

How to debug and start a multi core project?

Setting a breakpoint in main at first Debug_log print and we got there but it will not print to console.

    Hi Andreas,

    I am using the AM263x MCU+ SDK 09.00.00.33, the IPC notify example works as expected:

    R5F_1|2|3 did go to abortion, because the program is ended on those R5F cores.

    Please check your syscfg file example.syscfg.

    Make sure the "Enable UART Log" is checked.

    The other thing is the correct COM port is connected to the UART emulator (like Tera Term) (there two COM ports for J34, one for XDS110 and one for UART0) the display will be on UART0.

    If you are not sure, please connect both COM ports to UART emulator.

    Best regards,

    Ming
