Reading file would overwrite reserved memory ** Failed to load 'hello_world.bin

[neuberfran]

Hi

I have issue in this tutorial (https://github.com/TechNexion/freertos-tn/tree/freertos_1.0.1_imx7d) in line:

fatload mmc 0:1 0x7F8000 hello_world.bin

issue is:

fatload mmc 0:1 0x7F8000 hello_world.bin
** Reading file would overwrite reserved memory **
Failed to load 'hello_world.bin'

PrintEnv Line 58

too three importants files in Yocto imx7d-pico/Hardknott configuration:

pico-imx7.conf

https://gist.github.com/paoloturim/a841a7516ee290456d7583fb601305b6

and imx7d-pico-pi-m4.dts (I'm not sure if this file is being used in the final DTB)

https://gist.github.com/paoloturim/6bc901a50ec2786e346bc1e3866dd970

and
local.conf

https://gist.github.com/paoloturim/d1d304225e127c0be3767981cc0ad11c

I stay trying solution based on this site: https://community.element14.com/products/devtools/single-board-computers/warp7/f/forum/30463/linux-d...

User griff0417 tells to include "imx7d-pico-pi-m4.dts". Ok. I include but baseboard_pico_pi.dtsi have issue:

https://gist.github.com/paoloturim/fc80f146fa681116fd24aad19c450287

issue is:
(I don't see anything wrong with line 52.)

I solved with two changes in device-tree files:

in imx7d.dtsi

I put status = "okay";

in rpmsg: rpmsg {

in imx7d-pico-pi-qca-m4.dts

I put:

reserved-memory {

rpmsg_vrings: vrings0@0x8ff00000 {

reg = <0x8fff0000 0x10000>;

no-map;

};

};

&

&rpmsg{

memory-region = <&rpmsg_vrings>;

vdev-nums = <1>;

reg = <0x9fff0000 0x10000>;

status = "okay";

};
