Adding mtest support in uboot on am3354.

Hi,

I have enabled mtest command support in uboot by defining

CONFIG_CMD_MEMTEST

CONFIG_SYS_ALT_MEMTEST,

CONFIG_SYS_MEMTEST_START = 0x80000000,

CONFIG_SYS_MEMTEST_END = 0x9000000 in board specific header file.

Run mtest command at u-boot prompt.

But, Uboot hangs when I execute, mtest 0x80000000 0x90000000.

Message I got :

mtest 0x80000000 0x90000000
Testing 80000000 ... 90000000:
Pattern 00000000 Writing... (hangs after.)

Please guide me what extra need to add or remove.

Thanks in advance.

Regards,

Pankil.

Versions of my u-boot is u-boot-2014.07-g7e537bf and SDK version is "ti-processor-sdk-linux-am335x-evm-01.00.00.00" .

Hi Pankil,

Can you try a higher start address, i.e. 0x8F000000?

There is an u-boot relocation at the beginning of the RAM (0x80000000), so I don't think you can perform memory test from u-boot.

Best Regards,
Yordan
