EMMC转接座使用:
下面三个选项在“输入芯片印字”下面输入“EMMC”即可看到:
EMMC_AUTO:速度8BIT(默认),智能识别-EMMC时就是它。
EMMC_AUTO_4BIT:4BIT,建议大多数芯片选择它,稳定。
EMMC_AUTO_1BIT:1BIT,以上两者均不能读时,可以选择它,虽速度慢但或许能挽救片内数据。
另外,芯片型号后面_1/4/8BIT@FBGA153/FBGA169等(其中1/4/8BIT表示速度不同;FBGA153和FBGA169分别表示芯片封装形式),和以上其实是一致的,只不过前面三个可以不用区分芯片型号而进行读写。


EMMC转接座读写闪迪、金士顿、东芝部分型号出现CRC错误的技改方法:
注意:
①先要确保芯片是正常的,有的芯片能读不能写,或者不能读都是不良的预兆。
②使用转接座时,VCCQ volt电压仅限使用3.3V,不可使用1.8V。
③如果转接座上的8个电阻不是100Ω[101],请先更换后不行再继续后面的操作。

EMMC选项下,点左侧的“设置”,调整VCC Adjust为2.7V再读写;
