Why do you have to insert the 221 emmc memory into the socket upside down to read it?

Question

Hello ,

1 Why do you have to insert the 221 emmc memory into the socket upside down to read it? Are there any other memories that need to be mounted backwards in the socket?

2. How to download pinout to emmc and ufs in jpg?

3. I need BGA photos of emmc/emcp and ufs memory with pinout in good quality and the entire set, for example in PDF? I will return the favor.

4. What new solutions does Z3X now offer or what are you working on to improve the box?

Regards, Michał

Answer 1

Hi Michał,

Regarding question 1, inserting the 221 eMMC upside down might be due to the socket design or pin mapping. It's always best to refer to the specific socket's manual. Other eMMC models sometimes have similar quirks based on the adapter used. You also get in on the action of explosive crashes and epic giveaways in escape road,
