Hi Pengfei,
Please refer the device tree: we reserve just 2GB out of 8GB
Please modify based on your customization.

Hi Suren Porwar
I have already modify linux Memory is 1GB
I set bootargs ="console=ttyS2,115200n8 earlycon=ns16550a,mmio32,0x02800000 root=/dev/mmcblk0p2 rw rootfstype=ext4 rootwait mem=1G"
there is the linux kernel log

SUI
Hi Pengfei,
Based on the device tree changes this is our observations:
The system is making several memory reservations:
If possible, increase the system memory beyond 1GB to accommodate all these reservations and let us know if it works? Or does reducing the CMA pool to 128MB help
Best Regards,
Suren
Hi Suren Porwar
1、Now I increase the system memory 2GB accommodate all these reservations the linux kernel start failed , there is 2GB log

Why I increase the system memory , the linux kernel start failed ?
why I reducing the CMA pool to 128MB , the linux kernel start failed ?
Best Regards
SUI
Hi Pengfei,
This thread also can be referred.
except change in pervious post, CMA need be put in 1GB range.
BR,
Biao
Hi Pengfei,
can you help share the Mem map in your system(2GB/1GB) just like this?
BR,
Biao
Hi Biao
There is my the Mem map in our system

Hi Suren,
Can you help check this thread? do you have a try on your EVM?

Hi Biao,
I tried to change the exisiting Linux kernel DTS file with the below changes:

As you can see I have configured the DDR memory to be 1GB and reduced the CMA memory to 256MB and still able to boot my AM62P EVM.
Attached is the device tree blob if the customer wants to test on our EVM with this.

Best Regards,

Hi Suren
Yes When I use CMA memory to 256MB , AM62P EVM board boot is ok
But the DDR memory is 8GB , I want use DDR 1GB
you can check
Best Regards
SUI
Hi I changed the DDR memory to be 1GB as you can see in the patch that I shared in my last reply.
Best Regards,
Suren
Hi Suren
I use the the patch that you shared in your last reply, the AM62P EVM board can not boot , the kernel boot failed .
Best Regards
SUI
Have you changed the u-boot as well or just linux kernel?
Best Regards,
Suren
Hi Suren
Now I use SBL boot mode , R5 SPL -> ATF -> OP-TEE -> Linux
So I remove uboot , I only modify linux kernel dts file
Best Regards
SUI
Hi Suren
Now I use falcon boot mode , R5 SPL -> ATF -> OP-TEE -> Linux
So I remove uboot , I only modify linux kernel dts file
Best Regards
SUI
Hi Pengfei,
So what's the observation on when you use Falcon boot mode?
Best Regards
Suren
Hi Suren
R5 SPL -> ATF -> OP-TEE is ok
But When I use 1GB ddr the linux can not boot ,and boot failed , if I use 8GB ddr the linux boot is ok
How to use 1GB ddr at linux and boot is ok ?
How to change linux kernel RAM is 1GB?
Best Regards
SUI
Please share your changes in order to replicate the issue on my end.
Best Regards
Suren
Hi Suren
If you want replicate the issue , you must use falcon boot mode , R5 SPL -> ATF -> OP-TEE -> Linux
there is my modify DTS file

Hi Pengfei,
Give me couple of days to replicate the setup. If you don't hear back by Monday of next week, please ping again.
Best Regards
