EMMC Samsung ISP detect bug

Hello. XGecu T56 dont detect KMQE60013M-B318 via isp connection. Other EMMC work fine. Did you check this?

I solder directly to the emmc chip. But it not detect. I tried on three single chips. I will try to pull up RST_n to high level.

Yes I applied 1.8 with external power. Pull Up RST_n dont change anything. Chip dont detect. When i add pull up resistors 22k to cmd and dat0. Chip detect, but with wrong csd and sid, and dont read and erase. I cant test it with adapter BGA221 because i cant find it to buy.

I tested many samsung and hynix chip bga221 EMMC v5.1 and all have detect problem. Only EMMC v5.1 have this problem. All lower version detect and read normal. Maybe this bug of programmer software.

Can you show your isp connection board. Maybe i do something wrong. And can you add link for buying bga221 adapter on ebay or alixpress.
