I have a Sandisk Ultra 128GB

I see there has been some success with similar devices, but Sergey doesn't create configs for monoliths, which is why I am asking in chat. Hoping someone will have some config advice.

In this topic the device is 64GB

but I have here 128GB with same ID, and 1 bank. how is this so? I would have thought it would have to be 2 banks.

anyone have any configs I can try out please?

Thanks a lot, I will try, but mine is 128GB and 1 bank.. do I just change capacity?

Edit, Nice Michal, thank you!

I am not sure if it is right, but I changed it a little.. changed capacity and doubled the blocks:

Retry

and now abracadabra, alacazam!

Canceled.

I only read around 6GB though, so need to read the whole thing now.

I wish skip page and other parameters were explained in the manual. It might help us with monoliths recover something at least for our customers, even if we don't get it 100 right every time. I think I understand skip page, but not all of it.

Brian, it is wrong. Do not change config. I give you correct config for this chip and you make it wrong. For your device you must find second bank.

I see, sorry about that, working late at night makes mistakes! Finding second bank means more CE + RB? or use join CE?
