Subject: AW: (EXT) Re: [PATCH 2/2] mtd: spi-nor: micron-st: Add support for output-driver-strength
Date: Mon, 4 Oct 2021 12:10:53 +0000	[thread overview]
Message-ID: <kcEE.Dc11rDoPQ8iRcxif5TBAOA.gESl4Bi51wE@vtuxmail01.tq-net.de> (raw)

Hello,

> Does the micron flash define the SCCR SFDP map?

As far as I can tell, it only defines the Basis SPI protocol and the 4-byte Adress Instruction Table.
Dunno when the SCCR SFDP map was added, but this flash only announces JESD216B (SFDP 1.6)

Is there some tool for dumping/decoding the SFDP available?

Best regards,
Alexander
