I am trying to have firmware_m4_X running on M4 core, and fimware_A7_Linux, runnin on Linux and them intercommunicating via RPMSx. If I upload them separately they work fine but after board reboot I want these two images to be started automatically.
The M4-firmware remote file "rproc-axujenas1-fw":
Board << cd /lib/firmware
Board >> ls
Board >> LICENCE.cypress_bcm4343 brcm regulatory.db regulatory.db.p7s rproc-axujenas1-fw
PC >> cd ../linux-5.10.10/arch/arm/boot/dts
PC >> cat *f-dk2-m4-examples.dts
//--//
&pinctrl {
m4_leds_orange_pins: m4-leds-orange-0 {
pins {
pinmux = <STM32_PINMUX('H', 7, RSVD)>;
};
};
m4_pwm1_pins_a_ch1: m4-pwm1-0-ch1 {
pins {
pinmux = <STM32_PINMUX('E', 9, RSVD)>;
};
};
};
&timers1 {
status = "disabled";
};
&axujenas1 --my made adjustment
{
compatible = "st,stm32mp1-rproc";
st,auto-boot = <1>;
status = "okay";
};
I have named remoteproc node called : "axujenas1", so it matches the firmware name on the board.
After I try to compile, the node is not found:
PC >> make ARCH=arm dtbs
DTC arch/arm/boot/dts/stm32mp157f-dk2-m4-examples.dtb
Error: arch/arm/boot/dts/stm32mp157f-dk2-m4-examples.dts:131.1-11 Label or path axujenas1 not found
FATAL ERROR: Syntax error parsing input tree

Makefile:1342: recipe for target 'dtbs' failed
make: *** [dtbs] Error 2
My question: Where this remoteproc node is defined and with what syntax? Can I add multiples?
