Linux/AM5728: CMEM and ti-mct-daemon

The software team have been notified. They will respond here.

Hi.
i think that ti-mct-daemon is important. and then, i guess ti-mct-daemon need enough to 16MB.
I write am57xx-evm-cmem.dtsi as below it.

/ {
reserved-memory {
#address-cells = <2>;
#size-cells = <2>;
ranges;

cmem_block_mem_0: cmem_block_mem@a0000000 {
reg = <0x0 0xa0000000 0x0 0x1000000>;
no-map;
status = "okay";
};

cmem_block_mem_1: cmem_block_mem@a1000000 {
reg = <0x0 0xa1000000 0x0 0x2000000>;
no-map;
status = "okay";
};

cmem_block_mem_2: cmem_block_mem@a3000000 {
reg = <0x0 0xa3000000 0x0 0x1600000>;
no-map;
status = "okay";
};

cmem_block_ocmc3: cmem_block_mem@40500000 {
reg = <0x0 0x40500000 0x0 0x100000>;
no-map;
status = "okay";
};
};

cmem {
compatible = "ti,cmem";
#address-cells = <1>;
#size-cells = <0>;

#pool-size-cells = <2>;

status = "okay";

cmem_block_0: cmem_block@0 {
reg = <0>;
memory-region = <&cmem_block_mem_0>;
cmem-buf-pools = <1 0x0 0x1000000>;
};

cmem_block_1: cmem_block@1 {
reg = <1>;
memory-region = <&cmem_block_mem_1>;
cmem-buf-pools = <8 0x0 0x400000>;
};

cmem_block_2: cmem_block@2 {
reg = <2>;
memory-region = <&cmem_block_mem_2>;
cmem-buf-pools = <1 0x0 0x1600000>;
};

cmem_block_4: cmem_block@4 {
reg = <3>;
memory-region = <&cmem_block_ocmc3>;
};
};
};

but, i found error.
when i see systemctl status ti-mct-daemon.service,

also, i can't see 0xa3000000, when i see /proc/cmem

root@am57xx-evm:~# cat /proc/cmem

I hope two problem will be resolved. (1. ti-mct-daemon.service is died, 2. 0xa3000000 )

Thanks a lot.

Hi.
we try to apply differenct cmem's configuration and resolve it.

but, i wonder what ti-mct-daemon.service is.
I want to get this document.

Thnaks a lot.
