Just an update for those … What would be the best way to implement this functionality if it is not there? This allows device-independent, JEDEC ID-independent, and forward- and backward compatible software support for the specified flash device families. A command instruction configures the device to Serial Quad I/O bus protocol. Block A page is the minimum size unit for writing and reading. command is 98h, while the JEDEC ID mode access mode is 90h. After I boot petalinux , Linux doesn't boot and doesn't progress. [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. When their quad or dual I/O mode is enabled, Micron and Macronix spi-nor memories don't reply to the regular Read ID (0x9f) command. Instead they reply to a new dedicated command Read ID Multiple I/O (0xaf). 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). execute command fed to cmd_in port. Works here fine. Both are used in 16bit mode.

Nonvolatile memory devices are assumed to power up in a read-only state. No response to the command get_jedec_id.

The simple solution is to add the 16bit part as new device. * This file is part of the flashrom project. I connected the SPI pins accordingly via CD4050 (except MISO, directly connected to the pro mini's pin12), also connected the RESET to GND. Viewed 456 times 0.
