Since the SST flash is not really CFI compliant, I have to use jedec_probe, right? I am trying to use "jedec_probe.c" on our ppc based board to support two different flash types (AMD AM29VL160xT and SSTI SST39LF160). Re: [PATCH v2 2/4] m25p80: Improve command handling for Jedec commands, Cédric Le Goater, 2020/07/21. * This file is part of the flashrom project. This patch is only for kernel version 3.10-ltsi. My suggestion is NOT to reduce the frequency in the HDF (leave it to 200MHz) BUT to increase the divider in the prescalar. The interface is divided into independent channels.

Works here fine. The updated JESD216B standard from 2013 also describes how to use capacities larger than 128 Mbit in a generic way (such capacities exceed the legacy 24-bit addressing mode and can't be used with the old commands … The dataflow in this bus protocol is controlled with four multi-plexed I/O signals, a chip enable (CE#), and serial clock (SCK). JEDEC standards and publications are designed to serve the public interest … Both are used in 16bit mode. Autonomie 18 / 14 Trays. XY: 322.6 x 135.9 mm Z: 7.62 mm / 12.19 mm.
