Hi, I have an error encountered when running some throughput test on my custom board based on LS1043 reference design board.

Here's the error message I get, I couldn't figure out if it's related to the hardware I design or software side.... hope to get some hint and feedback...

I have included the link to the error message in text file as below

Kindly advise and help.

Hello kl h,

Please check whether this problem is caused by DDR hardware or DDR controller configuration problem.

Under u-boot, please use "mtest" program to test DDR memory.

Please configure CMD_MEMTEST, CONFIG_SYS_MEMTEST_START and CONFIG_SYS_MEMTEST_END in u-boot and use "mtest" command in u-boot to test DDR memory.

For example,

#define CONFIG_SYS_MEMTEST_START 0x80000000
#define CONFIG_SYS_MEMTEST_END 0x9fffffff

Have a great day,
TIC
