Other Parts Discussed in Thread: AM62P5, AM62P
Tool/software:
Hi TI team:
We are using the am62p5 with SDK version 10.00.07.04. Our board uses 2G memory and the EVM board uses 8G memory.
Thus we modified the uboot file k3-am62p5-sk.dts:
diff --git a/arch/arm/dts/k3-am62p5-sk.dts b/arch/arm/dts/k3-am62p5-sk.dts

memory@80000000 {
- /* 8G RAM */
- reg = <0x00000000 0x80000000 0x00000000 0x80000000>,
- <0x00000008 0x80000000 0x00000001 0x80000000>;
+ /* 2G RAM */
+ reg = <0x00000000 0x80000000 0x00000000 0x80000000>;
device_type = "memory";
bootph-pre-ram;
};
Then we rebuild the uboot and replace the tiboot3.bin, tispl.bin and u-boot.img in the SD Card and boot. But the Linux kernel cannot start properly.
This is the boot log:

We tests on the EVM board again, and the results were the same.
Can you help analyze it？
