hi All,

I'm working with beagle bone black board and trying to enable mtest command in SDK 7.0 u-boot source. but i'm getting following error


Configuration:

include/configs/am335x_evm.h

 #define CONFIG_CMD_MEMTEST 1
 #define CONFIG_SYS_ALT_MEMTEST 1
#define PHYS_DRAM_1   0x80000000
#define CONFIG_SYS_MEMTEST_START    (PHYS_DRAM_1 + (64 * 1024 * 1024))
#define CONFIG_SYS_MEMTEST_END      (CONFIG_SYS_MEMTEST_START \
                             + (8 * 1024 * 1024))

Error:

U-Boot#  mtest 84000000 84000010 AAAAAAAA 1
Testing 84000000 ... 84000010:
