At best it is possible to have both memories working with double SPI configuration or single (QSPI0_A with quad SPI [2]). (And hence it is why I've asked Andrey for sharing his DTS files). > ______________________________________________________ > Linux MTD discussion mailing list > http://lists.infradead.org/mailman/listinfo/linux-mtd/ Note: [1] - https://elixir.bootlin.com/linux/latest/source/arch/arm/boot/dts/vf610-bk4.= dts#L235 [2] - https://elixir.bootlin.com/linux/latest/source/arch/arm/boot/dts/vf610-bk4.= dts#L491 Best regards, Lukasz Majewski -- DENX Software Engineering GmbH, Managing Director: Wolfgang Denk HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany Phone: (+49)-8142-66989-59 Fax: (+49)-8142-66989-80 Email: lukma@denx.de --Sig_/MDVXulJPWIcMdxwYi2hg6.N Content-Type: application/pgp-signature Content-Description: OpenPGP digital signature -----BEGIN PGP SIGNATURE----- iQEzBAEBCAAdFiEEgAyFJ+N6uu6+XupJAR8vZIA0zr0FAl0/awEACgkQAR8vZIA0 zr1vawf/dCZ2s8uAvQeKJ3Lwg29S8SpcyVmmQlwf3XSKgVFiLASoUWv/gkMckrPn 3VJOK28NrkokBwIxi9yCvI5fUITkPYbc/Y+00bqWGVkrPTbgqNEHnERAfO4FS3xj tA4ZW/cR2o+mN8oMKsElEzmWBznFJv/+oIMr7NfgcxS7oNWtA286brWws0ce9u3S hMa2aRlYFt+q6llx1mXn2OTOhmaJ9iQSWIKPU5DyFA7jeGATBcnva/KU4YBZHWOS +ggU7+CsfyMV+7b1MQPb9WLiMPxX1UyxngNPiyAoRvV2a98iDvGh+W6cIGHrVNn/ Z/m6TuVCFosobEMFXIwb9Z1swmLbzQ== =NZxW -----END PGP SIGNATURE----- --Sig_/MDVXulJPWIcMdxwYi2hg6.N-- --===============4562255988068053696== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline ______________________________________________________ Linux MTD discussion mailing list http://lists.infradead.org/mailman/listinfo/linux-mtd/ --===============4562255988068053696==--
