t1042 DDR3 memory lose data

uvmbox — Thu, 02 Jul 2020 05:05:41 GMT

I have t1042 custom board. i use QCVS to check initialization data, and calibarate memory. it passed all memory write-read tests. But when i start dubugger memory does not work. I see my custom DEADBEE5 initial data in memory monitor, but when i write FFFFFFFF most of cell becomes 00000000. and i cant run any application from RAM. i have several of MT18KSF51272HZ-1G6K2ZF SO-DIMM module the same behavior.
