Hi,
I tried to boot IMX7 M4 rtso demo firmware via remoteproc, but remoteproc failed with the following errors
[ 231.254433] remoteproc remoteproc0: powering up imx-rproc
[ 231.323519] remoteproc remoteproc0: Booting fw image rpmsg_rtos_ddr.axf, size 1311480
[ 231.323573] remoteproc remoteproc0: No resource table in elf

[ 231.323693] remoteproc remoteproc0: Failed to load program segments: -22
[ 231.323990] remoteproc remoteproc0: Boot failed: -22
It seems, remoteproc tries to load firmware at the address 0x1fff0000 from the binary's program header, which is not reserved in the device tree as well as in the linker file. But the section header has proper address segments.
Binary header:
Is there any way to make remoteproc driver use the section header? or did I miss anything in the device tree or linker script? Can anyone help me to resolve this issue?
here are my device tree changes,
