Hello,

I want to know how to configure 1GBDDR to boot?

I am using the sysconfig default configuration. Do I need to change the default configuration?

The device tree of uboot and kernel has been modified to the size of 1GB. Do you need to modify anything else?

I found this document and you can debug through jtag:

https://software-dl.ti.com/processor-sdk-linux/esd/AM62X/latest/exports/docs/linux/Foundational_Components/U-Boot/Apps-SPL-Debug.html\

and also this for AM64x

in general, if you have modified the device tree of U-Boot and the kernel to recognize the 1GB DDR, you may not need to modify anything else. However, if the default configuration of sysconfig does not support 1GB DDR, you may need to modify it accordingly.

I changed the parameters according to the manual, but it still can't start

1. Check the default configuration in sysconfig and make sure it is set to support 1GBDDR. If not, you may need to change the default configuration to support the 1GBDDR.

2. Modify the device tree settings in uboot and kernel to reflect the size of 1GBDDR. This may involve changing the memory settings and any other relevant configurations to ensure the system recognizes and utilizes the 1GBDDR properly.

3. Ensure that any other relevant configurations, such as bootloader settings, are also updated to support the 1GBDDR.

Look forward to your feedback
