multicore programming

[Vishnu123]

Hi,

I have taken the multicore example (hello world example) provided by nxp.

When I flash the code in the eval board (IMXRT1170 EVKB), its working fine. But once, I perform a reset on the eval board, the code whatever we flashed is not running. 

m4 core code is running from ram but while m7 core is running from flash. After reset m7 core code should run.

If you can provide a solution for this, then it would be helpful.

Hi @Gavin_Jia ,

Thank you for replying and I am glad to inform you that the issue is resolved. The issue was related to UART communication since both the master and slave uses UART 1. 

regards,

Vishnu

Hi @Vishnu123 ,

Thanks for your interest in NXP MIMXRT series!

In order to locate the issue faster, can you help me with the failure message information and error screenshot? As well, which SW button on the EVK did you use for the reset? It was working fine until the reset caused it to fail, and even after another reset, it still didn't function properly, did it?

Thanks in advance for your collaboration!

Best regards,
Gavin
