This doesn't sound good; Code: Commands: 0: serial 1: on-board nand flash 2: on-board nand flash (verbose) 3: slot 1 nand option card 4: slot 1 nand option card (verbose) 5: sdram test, 1 iteration 6: sdram test, continuous iterations IPL> 5 memTestDevice from 0x00030000to 0x10000000 Try again. When enabled, the tester becomes a host to the SDRAM Precharge controller. activity on the DDR2 SDRAM Controller local interface via the JTAG connector. 2. Description. This is the fastest tester compared to other testers that will take 25 sec. The M80885RCA DDR5 Receiver Test Application simplifies stress signal calibration used for testing the inputs of DDR5 SDRAM devices including DIMM, DRAM, RCD, and Buffer devices at the physical layer to ensure minimum required performance and interoperability. Then the SDRAM should store this data, I wish to take this data out of the DE1-SOC to a PC, for example.
