reboot issue of imx8mp android 13

leotang · ‎09-09-2024

Dear Sir,

Our company have designed a board based on imx8mp reference design.Now,We have an issue with 2G RAM

if we use 4G LPDDR4 RAM and flash android 13 image, and we issue a reboot command in the console port.Then,the board reboot without any problem.But if we use 2G LPDDR4 RAM and flash android 13 image.

It will show the error message blow.How can I fix the problem?

What cause the problem?

Thx

Hi

From the error log, the system is accessing NULL address, so we suspect that the system not know the real dram range, can you check your porting steps?

Best Regards
Zhiming

leotang · ‎09-10-2024

Dear Zhiming,

I just changed the RAM SIZE and the lpddr4 timing for 2G in the u-boot.So which part shoud I check?Could you point me the specific part I should check ,as I have no idea how to check

Thx

BRs,

Dear Zhiming,

I have modified the device tree as your example.

But I have got the same result.

The attachment is the full bootlog for reference.

How do I check the next step?

Thx

BRs,

Hi

Can you share modifications about PHYS_SDRAM_2_SIZE and PHYS_SDRAM_SIZE ?

Best Regards
Zhiming

leotang · ‎09-10-2024

Below is my define for PHYS_SDRAM_SIZE

But I don't define PHYS_SDRAM_2_SIZE

#define CONFIG_SYS_SDRAM_BASE 0x40000000
#define PHYS_SDRAM 0x40000000
#define PHYS_SDRAM_SIZE 0x80000000 /* 2 GB */
#define PHYS_SDRAM_2 0x100000000

Hi @leotang

Please try to modify memory node in dts referring below screenshot.

Best Regards

Dear Zhiming,

I have modified the porting you suggest

But it seems the same result.I have added the full boot log in the attachment for your reference.

Hi @leotang

Current aosp on my side is Android14, in order to be able to quickly test, i use it to test.

Here is my test on evk board, try to limint DDR size on software.

modifications:

There is no other place need to modify for 2GB DDR porting.

You can see that the system memory is 2GB and there is no crash on EVK board. Maybe you can try to re-calibrate and stress test the ddr.

Hi @leotang

Another inspiration is that you can try to comment or reduce gpu_reserved size in imx8mp.dtsi. The default 256MB of physical memory may be too much.
