Hi people! 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? Thank Alexandr
