Yes, I think we should. Reading the specification provided publicly by Macronix. For all the JEDEC IDs with the no SFDP flag in drivers/mtd/spi-nor/macronix.c All of them have a new version or a new chip with the same JEDEC ID that supports SFDP. There are 2 chips that Macronix does not provide spec. in public. I can ask Macronix technical support on these 2 chips. Erez "RDID" "Part." "Size" "Status" "SFDP status according to spec. or new chip replacing with same RDID and SFDP supported according to spec." c22012 MX25L2005(A) SZ_256K = 2Mb EOL MX25L2006E c22013 MX25L4005A SZ_512K = 4Mb EOL MX25L4006E c22533 MX25U4035 SZ_512K = 4Mb EOL MX25U4033E c22534 MX25U8035 SZ_1M = 8Mb EOL MX25U8033E c22016 MX25L3205D SZ_4M = 32Mb EOL MX25L3233F c22017 MX25L6405D SZ_8M = 64Mb EOL MX25L6406E / MX25L6433F c22018 MX25L12805D SZ_16M = 128Mb EOL MX25L12833F c22538 MX25U12835F SZ_16M = 128Mb EOL MX25U12832F c2253a MX66U51235F SZ_64M = 512Mb EOL MX25U51245G c22532 MX25U2033E SZ_256K = 2Mb EOL Have-SFDP! c22010 MX25L512E SZ_64K = 512Kb NO_REC Have-SFDP! c22015 MX25L1606E SZ_2M = 16Mb NO_REC Have-SFDP! c22536 MX25U3235F SZ_4M = 32Mb NO_REC Have-SFDP! c22816 MX25R3235F SZ_4M = 32Mb NO_REC Have-SFDP! c22537 MX25U6435F SZ_8M = 64Mb NO_REC Have-SFDP! c22019 MX25L25635E SZ_32M = 256Mb NO_REC Have-SFDP! c22539 MX25U25635F SZ_32M = 256Mb NO_REC Have-SFDP! c2201a MX66L51235F SZ_64M = 512Mb NO_REC Have-SFDP! c2253a MX25U51245G SZ_64M = 512Mb PROD Have-SFDP! c22314 MX25V8035F SZ_1M = 8Mb PROD Have-SFDP! c22815 MX25R1635F SZ_2M = 16Mb PROD Have-SFDP! c2201b MX66L1G45G SZ_128M = 1Gb PROD Have-SFDP! c2253c MX66U2G45G SZ_256M = 2Gb PROD Have-SFDP! c2261b MX66L1G55G SZ_128M = 1Gb NO_REC Spec. is not public c29e16 MX25L3255E SZ_4M = 32Mb PROD Spec. is not public EOL End of Life PROD Production NO_REC Not recommend On Wed, 10 Jul 2024 at 16:34, Esben Haabendal <esben@xxxxxxxxxx> wrote: > > Erez <erezgeva2@xxxxxxxxx> writes: > > > On Wed, 3 Jul 2024 at 09:12, Tudor Ambarus <tudor.ambarus@xxxxxxxxxx> wrote: > >> On 7/3/24 12:16 AM, Erez wrote: > >>> On Tue, 2 Jul 2024 at 07:00, Tudor Ambarus <tudor.ambarus@xxxxxxxxxx> wrote: > >>> > >>> The table below uses fixed width characters. > >>> > >>> ID Part.
