Dear all I was setting up the RISAF4 for STM32MP257, however, the partition with name "linuxkernel2" has a glitch where its size shows as given
Which is beyond the size of my LDDR4 set to 8Gb.
How to solve it? A quick reply will be appreciated.
Thanking you!
With regards
Amit
There are actually two glitches :
the first one is what I reported. The second one is in RISAB 5 and 6. The same address appears both in RISAB 5 and 6 and hence might cause overlap of memories.
Moreover, I have a question that in EV1 device-tree there is no linuxkernel1 and 2 partition. below I have shown the generated device tree by cubeMX and the one from EV-1 Device Tree:
Generated:
linuxkernel1: linuxkernel1@84000000 {
reg = <0x0 0x84000000 0x0 0x76800000>;

/* USER CODE END linuxkernel1 */
};

};
};
From EV1:

no-map;

no-map;
};
ltdc_sec_rotation: ltdc-sec-rotation@ff000000 {
reg = <0x0 0xff000000 0x0 0x1000000>;
no-map;
};
/* global autoconfigured region for contiguous allocations */
linux,cma {
compatible = "shared-dma-pool";
reusable;
alloc-ranges = <0 0x80000000 0 0x80000000>;

linux,cma-default;
};
};
};
