Probleme with emmc with vccq =1,8v cant detect with supp or isp.
Hi, problem with emmc have vccq - 1.8v, can not detect, it gave me the initial emmc and failed - error: 00FF8081, when I use an external 1.8v, it tries to read the information, read cid csd successfully but error to read ecsd and failed - no data response state: I tried to measure vccq either in isp or on the emmc support , it is either absent or it is of low value -max 1.4v-.[attach]128[/attach]

[attach]130[/attach] Maybe it's your adapter problem. 1.8V is powered by U4 LDO XC6206-1.8V on EMMC adapter.[size=12px]
