I work with based on AT91RM9200 board. (SDRAM 16Mbitx16) When i use "mtest" then U-BOOT does not work But if to change a line #define CFG_MEMTEST_END CFG_MEMTEST_START + PHYS_SDRAM_SIZE - 262144

to a line

#define CFG_MEMTEST_END CFG_MEMTEST_START + PHYS_SDRAM_SIZE - 2000000 works correctly

How to solve a problem?

Hi,

it seems the mtest is overwriting heap and stack. AFAICT it would suffice to use #define CFG_MEMTEST_END CFG_MEMTEST_START+PHYS_SDRAM_SIZE-1220608

(PHYS_SDRAM + PHYS_SDRAM_SIZE - TEXT_BASE + CFG_MALLOC_LEN + CONFIG_STACKSIZE - 4)
