Re: [PATCH v2 2/4] m25p80: Improve command handling for Jedec commands… The dataflow in this bus protocol is controlled with four multi-plexed I/O signals, a chip enable (CE#), and serial clock (SCK). 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 … This is done by changing the prescaler using an API call in standalone or by changing the device tree entry for the QSPI.

The Query addressing is always relative to the device word (largest supported) with data always presented on the lowest order byte (D7 - D0 outputs). I connected the SPI pins accordingly via CD4050 (except MISO, directly connected to the pro mini's pin12), also connected the RESET to GND.

The current implementation only returns three bytes, and interprets the remaining three bytes as new commands. This patch initializes the jedec_id in the flash data structure so that the write_ear() function will send the correct bank-select command to the device. Since the SST flash is not really CFI compliant, I have to use jedec_probe, right? Stack 18 kg Tray 950 g.

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). Table 2. My suggestion is NOT to reduce the frequency in the HDF (leave it to 200MHz) BUT to increase the divider in the prescalar.
