Hanging timer interrupts on the LED pin by m4 app. Before linux is fully started, the meander is displayed correctly. After a full start, the meander breaks off and does not work as it should. Tried adding epit1 epit2 status disabled in the device tree, nothing changed.
Before starting linux
After starting linux
In the file imx6sxea-com-kit_v2-m4.dts tried
&epit1 {
status = "disabled";
};
&epit2 {
status = "disabled";
};
In the file imx6sxea-com-kit_v2-m4.dts tried (also tried to comment out epit)
epit1: epit@020d0000 {
reg = <0x020d0000 0x4000>;
interrupts = <GIC_SPI 56 IRQ_TYPE_LEVEL_HIGH>;
status = "disabled";
};
epit2: epit@020d4000 {
reg = <0x020d4000 0x4000>;
interrupts = <GIC_SPI 57 IRQ_TYPE_LEVEL_HIGH>;
status = "disabled";
};
Please advise in which direction to look
