Because 0x61000000-0x61100000 belongs to another existing region, `adsp_dma_mem`. It's slightly confusing because the diff doesn't show that directly... here's its snippet for ref: adsp_dma_mem: memory@61000000 { compatible = "shared-dma-pool"; reg = <0 0x61000000 0 0x100000>; no-map; }; Regards, Fei > > Cheers, > Angelo > > > no-map; > > }; > > > >

Corsola firmware reserves the memory region of [0x60000000, 0x61100000) exclusively for ADSP usage. But in fact, a 6 MB "hole" of [0x60A00000, 0x61000000) didn't get assigned to the ADSP node in the Corsola device tree, meaning no audio tasks can access and utilize that memory section. Update the reserved ADSP memory region to fill the gap.
