Do we have NXP boards with a NAND flash, to avoid board HW modifications? |
|
Hi @butok , this is requirement from customer. RW612+W25N01 is the expected combination |

Hi @kartben |
I think it's just a GitHub limit |
OK, it means the limit is 15. |

Add device tree binding for ONFI-compatible NAND flash devices connected to NXP FlexSPI controllers. The binding extends the base FlexSPI device binding and includes soc-nv-flash.yaml to inherit the write-block-size and erase-block-size properties. Device geometry (page size, pages per block, total capacity) is probed at runtime from the ONFI parameter page. Signed-off-by: Ruijia Wang <ruijia.wang@nxp.com>

@ofirshe Hi your recent commit update the dts. However, samples/drivers/memc/boards/frdm_rw612.overlay was not updated accordingly, it still sets spi-max-frequency on &w25q512jvfiq, which now points to the soc-nv-flash child node. Since soc-nv-flash.yaml does not declare spi-max-frequency, the DTS validation fails. |

self assigned, this is NXP driver, thanks. |
Add memc_flexspi_apply_pinctrl() for configuring additional FlexSPI port pins when init is skipped due to XIP, and memc_flexspi_update_lut() for runtime LUT updates using a stack buffer to avoid XIP pointer rejection. Guard all irq_lock() calls with CONFIG_FLASH_MCUX_FLEXSPI_XIP so non-XIP systems do not incur unnecessary interrupt latency. Signed-off-by: Ruijia Wang <ruijia.wang@nxp.com>
Add a SPI-NAND flash driver for NXP FlexSPI controller. The driver probes device geometry (page size, OOB size, pages per block, total capacity) from the ONFI parameter page at runtime and supports read, write, and block erase operations. Bad-block detection and marking are exposed through the flash_ex_op interface, including the FLASH_EX_OP_IS_BAD_BLOCK and FLASH_EX_OP_MARK_BAD_BLOCK operations.

Add Winbond W25N01GV (1 Gbit SPI NAND) device node to the FRDM-RW612 common DTS on FlexSPI PortB1 (CS2), disabled by default. The node is pin-compatible with the aps6404l PSRAM footprint at U12; enable at most one via devicetree overlay. write-block-size and erase-block-size are set to match the W25N01GV page and block geometry. Add pinctrl entry for FlexSPI PortB1 PSRAM/NAND pins and document the optional board rework procedure in the board documentation. Signed-off-by: Ruijia Wang <ruijia.wang@nxp.com>
Add configuration option and implementation for using an FTL (Flash Translation Layer) block device as storage backend for the littlefs sample, enabling the sample to run on NAND flash through the Dhara FTL disk driver. Signed-off-by: Ruijia Wang <ruijia.wang@nxp.com>
Add a build-only twister scenario for the W25N01GV NAND flash on FRDM-RW612, exercising LittleFS over Dhara FTL over FlexSPI NAND. The scenario is marked build_only: true as CI does not have hardware with NAND soldered. Signed-off-by: Ruijia Wang <ruijia.wang@nxp.com>
After commit b1afb49 ("flash: nxp: align FlexSPI NOR DTS with soc-nv-flash layout"), the w25q512jvfiq label points to the soc-nv-flash child node instead of the nxp,imx-flexspi-nor controller. Setting spi-max-frequency on &w25q512jvfiq causes a devicetree validation error because soc-nv-flash.yaml does not declare this property. Fix by referencing &ext_flash_ctrl (the flash controller node) instead. Signed-off-by: Ruijia Wang <ruijia.wang@nxp.com>

Add a ONFI-compatible NAND flash driver for NXP FlexSPI controller on FRDM-RW612. Replaced the on-board PSRAM with the W25N01GV NAND.
NFTL RFC is merged #50795.
Build NAND littlefs sample with command:
west build -p always -b frdm_rw612 samples/subsys/fs/littlefs -- -DEXTRA_CONF_FILE="boards/frdm_rw612_nand.conf" -DEXTRA_DTC_OVERLAY_FILE="boards/frdm_rw612_nand.overlay"
