Post subject:  MicroSD 2nd Bank

as anyone seen this pinout with a 2nd bank? I assume R/B (2A) is connected internally for all banks. I tried each empty pad for usual pinout but no second bank. Device is SanDisk 128GB. With config for 64GB, one bank I can get good layout, but must be 2nd bank somehow.

Thanks in advance for any ideas

I recovered some time ago same card. Here is the model: http://www.flash-extractor.com/library/ ... 9b_92__1x2 There is two banks. I don't even make any info in my resources about second bank, because it was easy to find. In fact you have three possibility: A1, G1, D3.

Thanks. I tried each. using CE1. with A1 and G1, other banks showed FF FF FF FF, with D3 showed 00 00 00 00

one thing I did not try was CE0 and setting join CE.

I should not need to add extra R/B right?

Thanks
