I create sample project for CPU0 and CPU1 of LPC55S69 using LPC55S69-EVK and EWARM ver 8.40.1.
I can debug the project for CPU0, but I cannot debug the project for CPU1.
If I set CPU1CLKEN in the CPUCTRL register to 1, I can debug the project for CPU1.
Therefore I believe that the following description of CPU1CLKEN in the user manual rev 1.3 is incorrect.
3 CPU1CLKEN RW CPU1 clock enable. 0x1
0 The CPU1 clock is enabled.
1 The CPU1 clock is not enabled.
I believe that we need to set CPU1CLKEN to 1 to enable CPU1 clock.
Am I correct?
Please reply as soon as possible.
Best regards,
Takashima
Hello Isao Takashima,
Yes, you are right. I will report this issue to Document team.
Also you can have a look at the multicore demo under SDK, for example the simple Hello_world:
set CPUCTRL bit3 to 1:
You can download the SDK package from: https://mcuxpresso.nxp.com/en/select
Hope it helps,
Have a great day,
TIC
