.. zephyr:code-sample:: jesd216 :name: JESD216 flash :relevant-api: flash_interface Use the JESD216 flash API to extract information from a compatible serial memory device. Overview ******** This sample demonstrates how to use the JESD216 flash API to extract information from a compatible serial device, and serves as utility to generate ``jedec,spi-nor`` devicetree property values for the device. Building and Running ******************** The application will build only for a target that has a devicetree entry with ``jedec,spi-nor`` as a compatible, and for which the driver supports :kconfig:option:`CONFIG_FLASH_JESD216_API`. .. zephyr-app-commands:: :zephyr-app: samples/drivers/jesd216 :board: efr32mg_sltb004a :goals: build flash :compact: Sample Output ============= .. code-block:: console MX25R8035F: SFDP v 1.6 AP ff with 3 PH PH0: ff00 rev 1.6: 16 DW @ 30 Summary of BFP content: DTR Clocking not supported Addressing: 3-Byte only 4-KiBy erase: uniform Support QSPI XIP Support 1-1-1 Support 1-1-2: instr 3Bh, 0 mode clocks, 8 waits Support 1-1-4: instr 6Bh, 0 mode clocks, 8 waits Support 1-2-2: instr BBh, 0 mode clocks, 4 waits Support 1-4-4: instr EBh, 2 mode clocks, 4 waits Flash density: 1048576 bytes ET1: instr 20h for 4096 By; typ 48 ms, max 384 ms ET2: instr 52h for 32768 By; typ 240 ms, max 1920 ms ET3: instr D8h for 65536 By; typ 480 ms, max 3840 ms Chip erase: typ 6144 ms, max 36864 ms Byte program: type 32 + 1 * B us, max 192 + 6 * B us Page program: typ 896 us, max 5376 us Page size: 256 By Suspend: B0h ; Resume: 30h DPD: Enter B9h, exit ABh ; delay 40000 ns ; poll 0x3d size = <8388608>; sfdp-bfp = [ e5 20 f1 ff ff ff 7f 00 44 eb 08 6b 08 3b 04 bb ee ff ff ff ff ff 00 ff ff ff 00 ff 0c 20 0f 52 10 d8 00 ff 23 72 f5 00 82 ed 04 b7 44 83 38 44 30 b0 30 b0 f7 c4 d5 5c 00 be 29 ff f0 d0 ff ff ]; PH1: ffc2 rev 1.0: 4 DW @ 110 sfdp-ffc2 = [ 00 36 50 16 9d f9 c0 64 fe cf ff ff ff ff ff ff ]; PH2: ff84 rev 1.0: 2 DW @ c0 sfdp-ff84 = [ 00 00 f0 ff ff ff ff ff ]; jedec-id = [c2 28 14];
