NOTICE JEDEC standards and publications contain material that has been prepared, reviewed, and approved through the JEDEC Board of Directors level and subsequently reviewed and approved by the JEDEC legal counsel. Upon module probing I am expecting the JEDEC ID of the device as 0x20BA19. Autonomie 66 / 32 Trays. [PATCH 1/2] mtd: m25p80: Rework probing/JEDEC code From: Anton Vorontsov Date: Tue Aug 18 2009 - 17:46:29 EST Next message: Anton Vorontsov: "[PATCH 2/2] mtd: m25p80: Add support for CAT25xxx serial EEPROMs" Previous message: Marcel Holtmann: "Re: [PATCH 3/3] Drop platform sysfs support" In reply to: Anton Vorontsov: "Re: [PATCH 2/6] mtd: m25p80: Convert to device table matching" Data_out OUT:8 Data output. However, before Skylake, this field was only two bits wide and did not support this command. Instead they reply to a new dedicated command Read ID Multiple I/O (0xaf). Ask Question Asked 2 years, 9 months ago. Thanks, Quyen. The dataflow in this bus protocol is controlled with four multi-plexed I/O signals, a chip enable (CE#), and serial clock (SCK). Is there a way to read JEDEC ID for a given NAND/NOR flash device from user space? Re: [PATCH v2 2/4] m25p80: Improve command handling for Jedec commands, Cédric Le Goater, 2020/07/21. 235A Page 1 HIGH BANDWIDTH MEMORY (HBM) DRAM (From JEDEC Board Ballot JCB-15-54, formulated under the cognizance of the JC-42.3 Subcommittee on DRAM Memories, under item number 1797.99F, Rev. CS is native, no extra GPIO are used. Here's the description of this field from the Lynx Point chipset datasheet: 2:1 | FLASH Cycle (FCYCLE)—R/W. Sigh.

Table 2. 1Scope The HBM DRAM is tightly coupled to the host compute die with a distributed interface. [2/3] m25p80: Improve command handling for Jedec and unsupported commands. My suggestion is NOT to reduce the frequency in the HDF (leave it to 200MHz) BUT to increase the divider in the prescalar. m25p80 driver while probing always returns 0 for JEDEC ID response command (0x9e/0x9f). JEDEC SOLID STATE TECHNOLOGY ASSOCIATION SEPTEMBER 2012 JEDEC STANDARD DDR4 SDRAM JESD79-4. Just an update for those … (Original link) Spansion - App Note - CFI Spec, 2008.

[PULL 08/11] m25p80: Improve command handling for Jedec commands: Date: Tue, 17 Mar 2020 11:40:36 +0000 : From: Guenter Roeck When requesting JEDEC data using the JEDEC_READ command, the Linux kernel always requests 6 bytes. This patch is only for kernel version 3.10-ltsi. XY: 322.6 x 135.9 mm Z: 7.62 mm / 12.19 mm. No response to the command get_jedec_id.

If the Read ID (0x9f) command fails (the read ID is all 1's or all 0's), then the Read ID Multiple I/O (0xaf) is used, first with SPI 4-4-4 protocol (supported by both Micron and Macronix memories), lately with SPI-2-2-2 protocol (supported only by Micron memories). 1Scope the HBM DRAM is tightly coupled to the host compute die with distributed...
