Jailhouse on S32G - Problems with MMC Interrupt

JoLe_VT — Thu, 27 Oct 2022 13:57:44 GMT

Hello together,

i want to enable the Jailhouse Hypervisor on the S32G (Gen2).
So far, the hypervisor works in principle (you can find the configs for the RDB1 Board here: https://github.com/lfd/jailhouse/tree/s32g).

But as soon as i start the hypervisor, the MMC interrups stop (no more mmc interrupts are triggered after starting the hypervisor).

Is there anybody who is working on the Jailhouse hypervisor and the S32G?

So far i found some projects working with the S32V and the Jailhouse HV, but they didn't have any similar problem.
Is there a difference between the interrupt system for the S32G and the S32V concerning the MMC Interrupt?

HI Johannes

Thank you for using NXP portal .Hope you are doing well

(A1) No , there are no any who working with Jailhouse hypervisor and the S32G ,

There are few people which working on Jailhouse hypervisor and the IMX. if you want help, i can transfer your question.

(A2) There are version difference in interrupt system of S32G and S32V. S32g uses GIC500 V3 while S32V uses GIC400 V2.

for eMMC S32G , you can refer eMMC Enablement and Debugging Tips Document (Document Number: AN13667) as reference.
