Did you check that there is actually SRAM here? Yes, I did some checking (mmap). But I repeated measurement and found mirrored regions: - SRAM_C is mirrored from 0x0000_4000 (primary location) to 0x01d0_4000 (size 0xb000) (probably exact size is 0xb0c0) - rest of 0x01d0_0000 are discontinuously filled with R/W register sets (probably some internals registers from VE) that I thought to be SRAM too - register SRAM_CTRL_REG0==0x01c00_0000 (value 0x7fff_ffff) switch whole region 0x01d0_0000-0x01df_ffff __AND__ 0x0000_4000-0x0000_ffff - VE/cedrus code use this regions indirectly (VE_AVC_SRAM_PORT_OFFSET/VE_AVC_SRAM_PORT_DATA...) and it is not influenced by "true" SRAM mapping or size -> so I suppose to better use only SRAM_C lower definition: --- diff --git a/arch/arm/boot/dts/sun8i-v3s.dtsi b/arch/arm/boot/dts/sun8i-v3s.dtsi index e8f304125e2d..90d703e5b73b 100644 --- a/arch/arm/boot/dts/sun8i-v3s.dtsi +++ b/arch/arm/boot/dts/sun8i-v3s.dtsi @@ -162,17 +162,17 @@ syscon: system-control@1c00000 { #size-cells = <1>; ranges; - sram_c: sram@1d00000 { + sram_c: sram@4000 { compatible = "mmio-sram"; - reg = <0x01d00000 0x80000>; + reg = <0x4000 0xb000>; #address-cells = <1>; #size-cells = <1>; - ranges = <0 0x01d00000 0x80000>; + ranges = <0 0 0x4000 0xb000>; ve_sram: sram-section@0 { compatible = "allwinner,sun8i-v3s-sram-c1", "allwinner,sun4i-a10-sram-c1"; - reg = <0x000000 0x80000>; + reg = <0x0 0xb000>; }; }; }; --- Does someone have accessible specific documentation of VE/cedrus for V3s ?
