The SAI module is not supported in QEMU, so the access of the register failed.

you can add bypass the access in QEMU, for example:

diff --git a/hw/arm/fsl-imx6ul.c b/hw/arm/fsl-imx6ul.c index e0128d7316..62f7bd92a4 100644 --- a/hw/arm/fsl-imx6ul.c +++ b/hw/arm/fsl-imx6ul.c @@ -534,6 +534,10 @@ static void fsl_imx6ul_realize(DeviceState *dev, Error **errp) */ create_unimplemented_device("sdma", FSL_IMX6UL_SDMA_ADDR, 0x4000);

• create_unimplemented_device("sai1", 0x02028000, 0x4000);
• create_unimplemented_device("sai2", 0x0202c000, 0x4000);
• create_unimplemented_device("sai3", 0x02030000, 0x4000);

Ah, yes, that takes care of the problem.

Thanks, and sorry for the noise.
