iMX6DL 目前使用 ddr test tool 2.8.0 進行檢測 PCBA 的 ddr calibration 時,出現 Error : Failed during ddr calibration 後來嘗試用 register configuration 更換 inc file 參數,還是顯是同樣的訊息。請問是什麼原因 ?
( DDR part number : MT41K128M16JT-125:K , 請參考我附件資訊 )
Hi Maco
from attached Calibration log.txt.zip log seems that memory is not working at all.
May be suggested to check memory signals with oscilloscope and recheck guidelines given in
