2c 84 d8 32

October 2nd, 2019, 7:52

Hi,
anyone see a BGA152 with ID 2c 84 d8 32 ? Trying to work out a config for it, but currently not getting results. Chip has no part number on it.
Drive has a CBM2199 SOIC-24 controller.

Supposedly, this is a Micron B05A based chip.

Further to this, using closest datasheet I can find (B95A) (MT29F128G08E[B/F]EBB, MT29F128G08E[B/E]CBB MT29F512G08EMCBB), I issued following commands:

command 90 result:

Code:
2C84D832A1000000


command ec result:

command ed result:

haven't had time to go further, but as this is urgent, hoping someone has some idea on proper config.
Cheers

Ask Sergey to make a CFG in NR...

It's Intel NAND, so maybe google this datasheet:
L85C_plus_128_256_512Gb_1Tb_2Tb_Async_Sync_NAND.pdf

Page 89 explains the table..
Memory organization block on page 90 looks promising...

Unless I'm missing something..

Thanks, yes I would if I had some time, but cant get in lab to setup PC for him.

I have a Micron account, but cannot find any datasheet where the exact number matches, or ID appears in it.

That datasheet is for MLC, as far as I can tell this one is TLC.

The part number in the dump leads to the datasheet B95A_128Gb_256Gb_512Gb_Async_Sync_NAND.pdf

I'm concerned that byte 2 and 3 don't appear in it.

I would say the d8 32 is wrong, but did references to it in flash circles.

[url]B05A has already flowed out, supporting ID: 2C, 84, D8, 32, A1, 00. ID: 2C, 84, 58, 32, A1, 00 flash memory is not supported, the modification is useless, firmware problem. 2258H supports 2C, 84, 58, 32, A1, 00, absolutely f--k![/url]

The only reference to B05A flash family at Micron is a few MCP packages, but no datasheets. The above poorly translated quote, I think is referring to problems trying to interchange 2c 84 d8 32 and 2c 84 58 32.

In new release of VNR we added new function to pars ONFI and JEDEC pages. You can send me data that goes as an output from 0xEC command, we will check it.
