Add chip W25NO1KV

[Kiwimannen]

Hello, Im trying to connect Winbond chip W25NO1KV and tried doing it manually by editing spi_nand_flash.c

SPINAND raw ID: EF AE 21 
spi-nand: spi_nand spi_nand@0: Winbond W25N01KV SPI NAND was found.
spi-nand: spi_nand spi_nand@0: 128 MiB, block size: 128 KiB, page size: 2048, OOB size: 94, ECC strength 4/512, custom ECC status.

#define _SPI_NAND_DEVICE_ID_1_W25N01KV          0xAE
#define _SPI_NAND_DEVICE_ID_2_W25N01KV          0x21

        {
                mfr_id:                                 _SPI_NAND_MANUFACTURER_ID_WINBOND,
                dev_id:                                 _SPI_NAND_DEVICE_ID_1_W25N01KV,
                dev_id_2:                               _SPI_NAND_DEVICE_ID_2_W25N01KV,
                ptr_name:                               "WINBOND W25N01KV",
                device_size:                            _SPI_NAND_CHIP_SIZE_1GBIT,
                page_size:                              _SPI_NAND_PAGE_SIZE_2KBYTE,
                oob_size:                               _SPI_NAND_OOB_SIZE_64BYTE,
                erase_size:                             _SPI_NAND_BLOCK_SIZE_128KBYTE,
                dummy_mode:                             SPI_NAND_FLASH_READ_DUMMY_BYTE_APPEND,
                read_mode:                              SPI_NAND_FLASH_READ_SPEED_MODE_DUAL,
                write_mode:                             SPI_NAND_FLASH_WRITE_SPEED_MODE_SINGLE,
                feature:                                SPI_NAND_FLASH_FEATURE_NONE,
        },

Cant set OOB_SIZE_94BYTE and I dont know why it says 128MiB since its a 1GBIT chip

recompiled, but can never connect:

well done

[Kiwimannen]

Thanks, I removed the old files and downloaded again, compiled (and checked the code to see it was there) - but it is still not able to detect the chip unfortunately.

Im looking at my equipment to see if anything is connected the wrong way, but it does not seem so ?

I will keep trying :)

Check the voltage is correct？

[Kiwimannen]

Yes, its checked. Im thinking it might have to do with that I am using a usb-c to usb-a adapter (in a laptop) to connect ?

But the same setup has worked for other chips.

Will have to install on another computer to check that.

[Kiwimannen]

Just an update - its probably the poor quality of my clip that causes problems and I cant remove the chip from the board.
Ordering a professional clip instead that probably/hopefully will work.
Again - very thankful for the add of this chip!
