AM2432: Reset R5 core from MCU domain

Konishi, Manabu

Part Number: AM2432

Hi,

Can MCU domain reset specific one R5 core?

SDK API "SOC_generateSwWarmResetMainDomainFromMcuDomain (void)" seems reset all R5 core in main fomain, but customer want to specific one R5 core from MCU domain.

Is there any method to reset a R5 core?

Hello Konishi-san,

I will have our Reset expert verify this when they return to office next week, but from reading through the Reset section of our Technical Reference Manual and reviewing each reset, I don't see one that resets a specific R5 core instead of all of them.

Unless I get information otherwise, it does not look like there is a method to reset a single R5 core.

Hello Konishi-san,

Got confirmation that there isn't a same-domain core-specific reset option for AM243x at all and by extension there is not one from MCU domain to the MAIN domain as well.
