XRDC clock enable

sobo — Thu, 20 Feb 2025 12:45:19 GMT

Hello,

I'm using EB tresos with RTD 4.0.0 P20 D2403.

I don't find in MCU => McuModeSettingConf=>McuPeripheral PRTN1_COFB0_CLKEN[REQ30] to enable the clock for the module ?

How can I enable the clock for XRDC ?

In the code when i call RM_init() I have got a hard fault in Xrdc_Ip_Init_Privileged()

Which specific MCU derivative is the question related to?

It's on a S32K358.

after further tests, it's seems that it's because i don't configure XRDC memory domain correctly.

I only want to use SEMA42, and it's quite annoying because it's seems i must use XRDC that for now i don"t need.
There is another way to implement "spinlock" / atomic instruction on S32K358 ?

No, it cannot be used separately. Trying to disable XRDC, having enabled SEMA42 lead in error.
