Tool/software:
Hi TI,
I am using SDK 8.2, cannot go to new SDK due to already released products. In my system PRU is operating at 250MHz. Below is the code for my DTS file. From calculations I found that my IEP is operating at 200MHz. I want to change my IEP frequency to 250MHz. how to do it, as I have tried changing it from dts by changing clock-parent and source but it did not work. I also tried to hard code the frequency but still it is 200MHz only.
icssg0_coreclk_mux: coreclk-mux@3c {
reg = <0x3c>;
#clock-cells = <0>;
clocks = <&k3_clks 62 19>, /* icssg0_core_clk */
<&k3_clks 62 3>; /* icssg0_iclk */
assigned-clocks = <&icssg0_coreclk_mux>;
assigned-clock-parents = <&k3_clks 62 3>;
};
icssg0_iepclk_mux: iepclk-mux@30 {
reg = <0x30>;
#clock-cells = <0>;
clocks = <&k3_clks 62 10>, /* icssg0_iep_clk */
<&icssg0_coreclk_mux>; /* core_clk */
assigned-clocks = <&icssg0_iepclk_mux>;
assigned-clock-parents = <&icssg0_coreclk_mux>;
};
};
};
icssg0_iep0: iep@2e000 {
compatible = "ti,am654-icss-iep";
reg = <0x2e000 0x1000>;
clocks = <&icssg0_iepclk_mux>;
This is the original dts which is part of sdk. I have change this to below icssg0_coreclk_mux: coreclk-mux@3c {
reg = <0x3c>;
#clock-cells = <0>;
clocks = <&k3_clks 62 19>, /* icssg0_core_clk */
<&k3_clks 62 3>; /* icssg0_iclk */
assigned-clocks = <&icssg0_coreclk_mux>;
assigned-clock-parents = <&k3_clks 62 3>;
};
icssg0_iepclk_mux: iepclk-mux@30 {
reg = <0x30>;
#clock-cells = <0>;
clocks = <&k3_clks 62 3>, /* icssg0_iep_clk */
<&icssg0_coreclk_mux>; /* core_clk */
assigned-clocks = <&icssg0_iepclk_mux>;
assigned-clock-parents = <&k3_clks 62 3>;
};
};
};
icssg0_iep0: iep@2e000 {
compatible = "ti,am654-icss-iep";
reg = <0x2e000 0x1000>;
clocks = <&icssg0_coreclk_mux>;
assigned-clock-rates = <250000000>;
};
icssg0_iep1: iep@2f000 {
compatible = "ti,am654-icss-iep";
reg = <0x2f000 0x1000>;
clocks = <&icssg0_coreclk_mux>;
assigned-clock-rates = <250000000>;
I am not able to get 250Mhz frequency for IEP. I tried to read the frequencies from k3conf tool it shows 200MHz only. and my calculations also give results for 200MHz.
Need support to update the IEP frequency to 250MHz.
