Dear TI supporters,
I have a project using AM6442. Currently I want to initialize the M4F core in WFI from the R5 u-boot-spl to start M4F firmware that is programmed before.
I am doing the driver for remoteproc like ti_k3_m4f_rproc.c to Start M4F core that is based on the ti_k3_arm64_rproc.c driver.
I add a node fore m4f remoteproc driver in the device tree as below:
cbass_mcu: bus@4000000 {
compatible = "ti,am64x-m4fss-rproc";
power-domains = <&k3_pds 61 TI_SCI_PD_EXCLUSIVE>, <&k3_pds 135 TI_SCI_PD_EXCLUSIVE>;
resets = <&k3_reset 135 0>;
clocks = <&k3_clks 61 0>;
assigned-clocks = <&k3_clks 61 0>, <&k3_clks 135 0>;
assigned-clock-parents = <&k3_clks 61 2>;
assigned-clock-rates = <200000000>, <1000000000>;
ti,sci = <&dmsc>;
ti,sci-proc-id = <24>; /* PROCID_MCU_M4FSS0_C0 */
ti,sci-host-id = <30>; /* M4_0(Non Secure): M4 */
u-boot,dm-spl;
};
But some element values I don't know to fill. Could you help me correct it.
For example: all of the following elements are of ARM64 (A53)
power-domains = <&k3_pds 61 TI_SCI_PD_EXCLUSIVE>, <&k3_pds 135 TI_SCI_PD_EXCLUSIVE>;
resets = <&k3_reset 135 0>;
clocks = <&k3_clks 61 0>;
assigned-clocks = <&k3_clks 61 0>, <&k3_clks 135 0>;
assigned-clock-parents = <&k3_clks 61 2>;
assigned-clock-rates = <200000000>, <1000000000>;
if I want to use them for M4F then how I should change them because I don't know the mean of number 135, 61?
M4F uses assigned-clock-rates = <400*1000000>, <400*1000000>; instead of assigned-clock-rates = <200000000>, <1000000000>; Is it right?
Thanks,
