Hi,

Im new to the DRAMeXchange, but looking for prices of USB flash drives with the SMI controller VendorID = 090c, shipped to the UK.

Thanks

Im working on a USB flash drive that has a little physical damage on the connector, but no other visible problems. It reports to be 0MB or uninitialised and no data can be read from the OS.

Controller Vendor: SMI
Controller Part-Number: SM3267AC - ISP 160128-1AC
Flash ID code: AD3A18A3 - Hynix H27UDG8M2MTR - 2CE/Single Channel TLC-16K -> Total Capacity = 32GB

Its a double sided board with the controller and one NAND on one side, and the other NAND on the other side. They are TSSOP and QFN parts which for me makes reflow work a lot easier than BGA, so I can take them off to read them externally Id have to get a reader for that. But before Im going the hardware route, Im wondering if the SMI controller has some sort of recovery mode or raw-read mode.

There are a number of MPTools from SMI that have debug portions that allow different kinds of access to the NAND, RAM, controller settings etc. but havent spotted a raw-NAND-read option. It does get detected properly including the NAND, so thats good, but Im not sure how to safely check NAND command availability using MPTool as its obviously intended for manufacturing testing and loading of preset images. I tried the udisk creation option which is supposed to create a low-level image for mass production, but that resulted in 32GB of nulls.

There is a bad block counter thats set to 99, but 97 of those are normal reserved bad block entries, code 80, which appears to not refer to actual bad blocks.
There are two entries in the bad block list that refer to something else:

New Bad Block : 2
=== >>>>> ===================================================================================================
New Block Index: 0, Block: 82, Page: 49, ErrorCode: 3
New Block Index: 1, Block: 86, Page: 3D, ErrorCode: 3
=== <<<<< ===================================================================================================

Other than that, the PCB and none of the chips get warm, the LED does light up but doesnt blink probably because there is no normal FTL activity.

I could start with some simple voltage probing to see if maybe some traces have micro fractures, but perhaps someone here knows of other software controlled testing/reading options for the SMI controllers?
